This book was released on 1994 with total page 23 pages. Available in PDF, EPUB and Kindle. Book excerpt: The goal of this project is to develop a cost-effective low temperature deNOx catalyst to be used in the Research Triangle Institute-Waterloo SO2/NOx process for boiler retrofit applications. The performance goal of the catalyst is to convert over 80% of the NO in the flue gas at a temperature as low as 150°C in the presence of 4% O2, and 10% water. Based on the results obtained in the previous quarter, which showed a La-Cu-ZrO2 catalyst to be a promising low temperature catalyst in the presence of 2% H2O in the reduction of NO to N2 with isobutanol, research was conducted to investigate the variations in feed conditions on the performance of the catalyst. Specifically, the effect of increased H2O concentration and the effect of NO2 in the feed were investigated. Although the activity of the catalyst declined when the H2O concentration was increased from 2 to 10%, the decline was relatively mild compared with that when the water content was changed from 0 to 2%. The effect of NO2 was investigated because oxidation of NO to NO2, a thermodynamically favorable process, proceeds at a finite rate even in the absence of a catalyst. It was found that, under the low temperature reaction conditions, replacement of NO2 with NO did not affect the catalytic performance of the La-Cu-ZrO2 catalyst. Besides studying the La-Cu-ZrO2 catalyst, effort has continued in screening other potential catalysts. A promising 5%Cu-2%Ag catalyst supported on active carbon was found that catalyzes NO reduction by acetone. At 150°C, 35% NO conversion was obtained in the presence of 4% O2 and 8% H2O at a space velocity of 3000 h−1 after 5 h on stream.

Book excerpt: The goal of this project is to develop a cost-effective low temperature deNOx catalyst to be used in the Research Triangle Institute-Waterloo SOx/NOx process for boiler retrofit applications. The performance goal of the catalyst is to convert over 80% of the NO in the flue gas at a temperature as low as 150°C in the presence of 4% O2 and 10% water. Based on the results obtained in the first quarter, which showed that modification of a Cu-ZrO2 catalyst with Nd increased the conversion of NO to N2, especially at higher partial pressures of oxygen, and that ethanol was a more effective reductant than propene in the presence of water vapor, research was conducted in this quarter to investigate the use of other modifiers and other alcohols as reductants. It was found that modification of Cu-ZrO2 by La was more effective than by Nd or Gd. It decreased the hydrocarbon combustion activity of the catalyst while increasing the NO conversion. A Cu-Ga2O3 catalyst was also tested. It was superior to Cu-ZrO2 at temperatures higher than 250°C, but inferior at lower temperatures. On the La-Cu-ZrO2 catalyst, isobutanol was a very effective reductant for NO, being more effective than ethanol. In the presence of 4% O2, 2% water, and with a space velocity of 3000 h−1, an NO conversion to N2 of 83% was obtained using 1200 ppM isobutanol at 200°C. This is believed to be the highest conversion reported to data without using NH3 as the reductant. Other catalysts not containing copper were also tested, but their performance was inferior to this La-Cu-ZrO2 catalyst.

This book was released on 1993 with total page 24 pages. Available in PDF, EPUB and Kindle. Book excerpt: The goal of this research is to develop a low temperature deNOx catalyst with activity high enough for boiler retrofit applications. Cu-ZrO2 is a promising low temperature catalyst for the selective reduction of No by propene. At NO = 1000 ppm, propene (C3H6) = 1000 ppm and 02 = 1% and a space velocity of 13,000 h−1, the NO conversion to N2 is 64% at 265°C. The performance of the catalyst, however, does not fulfill the requirement when used for flue gas clean up where the feed is composed of 4% O2 and 10% H2O, and the temperature is 150°C. Methods to improve the performance of the catalyst are being sought. These include modification of the preparation method such as varying the aging time of the gel after precipitation, and addition of promoters like Pd and Nd to increase the catalytic activity at lower temperatures and higher 02 concentrations. Using ethanol (C2H5OH) instead of C3H6 as a reductant improves the performance of the catalyst when H2O is present. Interestingly, methanol is not an effective reductant. Some modified carbon catalysts are also tested. Results on Cu impregnated ASC whetlerite carbon catalyst show 100% N2 selectivity and 35 % NO conversion at 200°C. However, the catalyst is unstable and deactivates rapidly. Work planned for the next quarter is to continue to investigate methods to improve the catalytic activity.

Quarterly Technical Progress Report No. 13, March 1, 1994--May 31, 1994 written by and published by . This book was released on 1994 with total page 43 pages. Available in PDF, EPUB and Kindle. Book excerpt: The NOXSO process is a dry, post-combustion flue gas treatment technology which uses a regenerable sorbent to simultaneously adsorb sulfur dioxide (SO2) and nitrogen oxides (NO3 from the flue gas of a coal-fired utility boiler. In the process, the SO2 is converted to a sulfur by-product and the NO3 is converted to nitrogen and oxygen. It is predicted that the process can economically remove 90% of the acid rain precursor gases from the flue gas stream in a retrofit or new facility. The objective of the NOXSO Demonstration Project is to design, construct, and operate a flue gas treatment system utilizing the NOXSO process. The effectiveness of the process will be demonstrated by achieving significant reductions in emissions of sulfur and nitrogen oxides. In addition, sufficient operating data will be obtained to confirm the process economics and provide a basis to guarantee performance on a commercial scale. The project is presently in the project definition and preliminary design phase. Data obtained during pilot plant testing which was completed on July 30, 1993 is being incorporated in the design of the commercial size plant. A suitable host site to demonstrate the NOXSO process on a commercial scale is presently being sought. Preliminary engineering activities involved evaluating various design options for the major process vessels with the principal focus being on the sorbent heater vessel, which is operated at the highest temperature. Additionally, the impact of the NOXSO system on power plant particulate emissions and opacity was estimated. It is predicted that particulate emissions will decrease slightly while opacity will increase slightly. Neither change will be significant enough to have an impact on emissions compliance. Advertised performance of the proposed adsorber separator is being verified by laboratory testing. Process studies activities included POC equipment inspection and materials evaluations.

Book excerpt: The goal of this project is to develop a cost-effective low temperature deNOx process. NOx removal at temperatures between 120C--150C was investigated using the approaches of (1) selective reduction of NOx by alcohol or acetone (2) adsorption of NOx with an effective sorbent. The chief problem encountered in low temperature reduction of NO was catalyst deactivation due to coke formation. In this quarter, a possible solution explored was increasing the loading of precious metals (Pd and Ag) on oxide supports, as precious metals are known to be effective in the oxidation of hydrocarbons at low temperatures. However, no improvement was observed. Another solution was the replacement of NO by NO2 in the feed for the carbon-based catalyst tested, as NO2 was observed to slow down the deactivation rate over Cu-ZrO2 catalyst. However, rapid reduction of NO2 to NO by the carbon support occurred, making this approach impractical. As part of this approach, search for better NO oxidation catalysts continued this quarter. It was found that on different carbon catalysts at 30C and a W/F of 0.01g.min/cc, NO conversion to NO2 between 82--90% can be achieved. This activity, however, decreased with increasing temperature. SO2 also poisoned the oxidation activity of the activated carbon. Au dispersed on lanthanum oxide was another catalyst tested and had an NO conversion to NO2 of 17% at 250C. The catalytic performance of this catalyst could be improved by increasing its surface area. Finally, the adsorption capacity of NOx of a carbon sample provided by ISGS and an inorganic sorbent were tested. The capacity of the inorganic sorbent was found to be much higher.

Book excerpt: Carbon adsorbents have been shown to remove sulfur oxides from flue gas, and also serve as a catalyst for reduction of nitrogen oxides at temperatures between 80 and 150°C. The overall objective of this project is to determine whether Illinois coal is a suitable feedstock for the production of activated char which could be used as a catalyst for combined SO2/NO3 removal, and to evaluate the potential application of the products in flue gas cleanup. Key production variables will be identified to help design and engineer activated char with the proper pore structure and surface chemistry to enable the development of an effective SO2/NO3 removal catalyst. The ISGS agreed to provide 500 pounds of activated char to STEAG for tests in a demonstration unit to clean flue gas from a U.S. waste incinerator. The STEAG process requires an activated char with a N2 BET surface area

This book was released on 1995 with total page 17 pages. Available in PDF, EPUB and Kindle. Book excerpt: The goal of this project is to develop a cost-effective low temperature deNOx process. Work done in previous quarters suggested that the best approach for NOx removal between 120 C and 150 C was the catalytic oxidation of NO to NO2, followed by adsorption of NO2 with an effective sorbent. The effort this quarter was concentrated on further evaluation of catalysts for NO oxidation. This included more detailed studies of Co/Al2O3 and searching for other active and stable catalysts. The initial increase and subsequent decline in NO oxidation activity of Co/Al2O3 in the presence of SO2 in the feed was investigated by measuring the dependence of NO oxidation activity on the time of pretreatment in a stream of 0.1% SO2, 4% O2 and 10% H2O. The results suggests that NO oxidation might be effected by SO3 that was formed by the oxidation of SO2, and the subsequent decline in activity might be due to the formation of stable inorganic sulfate. Au/Al2O3 was ineffective for NO oxidation. However, a 5 wt.% Au/Co3O4 catalyst (prepared by co-precipitation with Na2CO3 as the precipitating agent) showed high activity. At a W/F of 0.0071 g-min/cc, and a feed composition of 400 ppm NO and 4% O2, a NO conversion of 45% to NO2 at 200 C was obtained, but no activity was observed at 150 C. When H2O and SO2 were included in the feed, NO conversions between 48%--50% were observed between 120 and 150 C. The enhancement of NO oxidation activity by the presence of SO2 is of particular interest in view of the high sulfur content of the Illinois coal. Furthermore, this activity was stable for the 15 h duration that the catalyst was tested.

The impact of water desorption in the sorbent heater and water adsorption in the sorbent cooler has been quantified and incorporated into the NOXSO process simulator. NOXSO process economics has been updated based on the present design. Capital cost for a 500 MW plant designed to remove 98% of the SO2 and 85% of the NO3 is estimated at $247/kW.

This book was released on 1994 with total page 23 pages. Available in PDF, EPUB and Kindle. Book excerpt: Simultaneous removal of SO2 and NOx using a regenerable solid sorbent will constitute an important improvement over the use of separate processes for the removal of these two pollutants from stack gases and possibly eliminate several shortcomings of the individual SO2 and NOx removal operations. This process will allow simple and reliable cleanup of large volumes of stack gases at a competitive cost; produce a concentrated stream of SO2 which an easily be converted into valuable by-products; be compatible with existing power generation plants; and essentially eliminate the waste materials generated in some other sulfur removal processes. Department of Energys̀ Pittsburgh Energy Technology Center (PETC) and UOP/Shell have developed processes which both employ copper oxide-based sorbents in different reactor configurations, namely, former uses a regenerative fluidized bed while the latter employs a cyclic fixed bed contactor. More recent studies at PETC considered cerium oxide as an alternate sorbent to CuO{sup (1,2)}. Ceria improves the resistance of the alumina support to thermal sintering and produces a regeneration off-gas stream that can be easily converted to elemental sulfur. It has potentially higher sulfur capture capacity than copper. The objective of this research is to determine the effects of ammonia on the sulfation of the sorbent; to determine the effects of fly ash on the sulfation and regeneration of the sorbent; to obtain a rate expression for the regeneration of alumina-supported CeO2 sorbents; to model reactor configurations for a commercial scale combined CeO2/Al2O3 sorbent; and to study alternative designs, effects of design variables on the performance of the facility, and the economics of the process using the developed model.

This book was released on 1993 with total page 11 pages. Available in PDF, EPUB and Kindle. Book excerpt: The objective of the proposed research is to design and implement a novel scheme for the combined removal of SO2 and NO(subscript x) using a dielectric-barrier discharge in conjunction with UV irradiation. This investigation requires the design of a dielectric-barrier reactor and testing the proposed scheme under different conditions. The testing of the uniformity of the discharge with UV irradiation has been very successful. The details are provide-din this report and has been submitted to the Applied Physics Letter. In this reporting period both experimental and simulation work were carried out on the removal of SO2 and NO(subscript x). With the improved reactor, we have achieved a removal of SO2 up to 85%. The simulation studies indicate that complete removal of NO(subscript x) is possible at reduced electric fields (E/N) of above 100 Td.

This book was released on 1994 with total page 12 pages. Available in PDF, EPUB and Kindle. Book excerpt: The objective of this work is to develop a novel system for regenerable SO2 and NO(subscript x) scrubbing of flue gas that focuses on (a) a novel method for regeneration of spent SO2 scrubbing liquor and (b) novel chemistry for reversible absorption of NO(subscript x). In addition, high efficiency hollow fiber contactors (HFC) are proposed as the devices for scrubbing the SO2 and NO(subscript x) from the flue gas. The system will be designed to remove more than 95% of the SO(subscript x) and more than 75% of the NO(subscript x) from flue gases typical of pulverized coal-fired power plants at a cost that is at least 20% less than combined wet limestone scrubbing of SO(subscript x) and selective catalytic reduction of NO(subscript x). In addition, the process will make only marketable byproducts, if any (no waste streams). The major cost item in existing technology is capital investment. Therefore, our approach is to reduce the capital cost by using high efficiency hollow fiber devices for absorbing and desorbing the SO2 and NO(subscript x). We will also introduce new process chemistry to minimize traditionally well-known problems with SO2 and NO(subscript x) absorption and desorption. For example, we will extract the SO2 from the aqueous scrubbing liquor into an oligomer of dimethylaniline to avoid the problem of organic liquid losses in the regeneration of the organic liquid.

This book was released on 1993 with total page 46 pages. Available in PDF, EPUB and Kindle. Book excerpt: The objective of this project is to demonstrate the preliminary technical and economic feasibility of a novel carbon-based process for removal of at least 95 % SO2, and at least 75 % NO(subscript x) from coal combustion flue gas. In the process, flue gas leaving the electrostatic precipitator (ESP) is passed through a trickle bed of activated carbon catalyst employing a periodic flush of low strength sulfuric acid. The SO2 is oxidized to SO3 and removed as medium strength sulfuric acid. The SO2-free flue gas is then mixed with NH3, and the NO(subscript x) in the gas is subjected to selective catalytic reduction (SCR) to N2 over a fixed bed of activated carbon catalyst. In the previous six quarters, detailed project plans were prepared and experimental systems were commissioned. The SO2 removal factorial experiments with BPL carbon at 21°C are well underway at Waterloo. A modified carbon catalyst (MCCI) showed up to 99% SO2 removal in the presence of NO(subscript x) over 10 multiple cycles at 80--130°C and 1400 scc/cc/h. Several catalysts were evaluated for NO(subscript x) removal also. Promising modified carbon catalysts (MCCI, II and III) were tested. Some of these catalysts showed the potentialfor over 80% NO(subscript x) removal at space velocities as high as 3000 scc/cc/h. Poisoning of NO(subscript x) removal efficiency with SO2 in the feed was also studied. With over 100 ppm SO2 in feed, NO(subscript x)removal efficiency remained steady for several hours. It declined from 79% removal to 66% removal over 24 hours. NO(subscript x) removal experiments were performed with 5 different materials and the SO2 removalactivity of 2 catalysts was tested.
