Download or read book Evaluation of Simultaneous SO2/NOX Control Technology written by Kevin R. Bruce and published by . This book was released on 1993 with total page 2 pages. Available in PDF, EPUB and Kindle. Book excerpt: The Clean Air Act Amendments of 1990 (CAAA) have led to accelerated research into novel sulfur dioxide (SO2) and nitrogen oxide (NOx) control technologies for coal-fired industrial boilers. One of these technologies combines sorbent injection and selective non-catalytic reduction for simultaneous SO2/NOx removal. The work presented herein concentrated on characterizing three process operational parameters of this technology: injection temperature, sorbent type, and reductant/pollutant stoichiometric ratio. A slurry composed of a urea-based solution (NOx OUT A or NOx OUT A+) and various calcium-(Ca-) based sorbents was injected at a range of temperatures and reactant/pollutant stoichiometries in a natural-gas-fired, pilot-scale reactor with doped pollutants. Up to 80% reduction of SO2 and NOx at reactant/pollutant stoichiometric ratios of 2 and 1.5, respectively, was achieved. SO2 emission reductions from slurry injection were enhanced moderately when compared with dry sorbent injection methods, possibly caused by sorbent fracturing to smaller, more reactive particles. Emissions from ammonia (NH3) slip (unreacted nitrogen-based reducing agent) and nitrous oxide (N2O) formation were reduced in comparison with other published results, while similar NOx reductions were obtained. increased carbon monoxide (CO) emissions, caused by the decomposition of urea, were moderate. Emissions of CO, NH3, and N2O for the enhanced urea solution (NOx OUT A+) were substantially less than the levels observed during urea (NOx OUT A) injection. The injection of the urea-based solution enhanced SO2 removal, probably because of the formation of (NH4)2CA(SO4)2 H2O. The results of this pilot-scale study have shown high reduction of both SO2 and NOx.

Download or read book Plasma-Assisted Heterogeneous Catalysis for NOx Reduction in Lean-Burn Engine Exhaust written by B. Penetrante and published by . This book was released on 1997 with total page 8 pages. Available in PDF, EPUB and Kindle. Book excerpt: Recent developments in catalytic control of NOx are revealing the significance of NO2 as an intermediary for achieving higher NOx removal efficiencies. This paper discusses the combination of the plasma with a catalyst to improve the selective reduction of NOx under lean-burn conditions. It is shown that the main effect of the plasma is to enhance the gas-phase oxidation of NO to NO2. The reduction of NOx to N2 is then accomplished by the heterogeneous reaction of NO2 with activated hydrocarbons on the catalyst surface. By using a plasma, one can take advantage of a new class of catalysts that are potentially more durable, more active, more selective and more sulfur-tolerant compared to conventional lean-NOx catalysts. The plasma-assisted catalytic reduction process can be implemented with any type of plasma reactor and does not require a specific type of electrical power supply. It can also easily accommodate any type of catalyst support structure.

Download or read book NOx Removal by LNT-SCR Dual-layer Catalysts written by Yi Liu and published by . This book was released on 2012 with total page pages. Available in PDF, EPUB and Kindle. Book excerpt: The increasingly strict emission standards have driven the progress of NOx storage and reduction (NSR) technology. NOx is stored in a lean NOx trap (LNT) catalyst during fuel-lean mode and reduced to N2 during fuel-rich mode. First, we investigated the impact of ceria on NSR in an Pt/Ce LNT catalyst. The physisorbed oxygen over the ceria-containing LNT catalyst led to a spatio-temporal temperature rise in the monolith upstream after the cyclic introduction of H2/CO to a pre-oxidized catalyst. The stored oxygen over ceria enhanced NO storage by in-situ NO2 formation, while it competed with NO2 for storage sites. During the NOx reduction over the Pt/Ceria, the Pt surface purgation was the first step and the oxygen reduction preceded the NOx reduction. Second, we studied the NSR by dual-layer catalysts consisting of a selective catalytic reduction (SCR) catalyst layer on top of a LNT catalyst. During periodic switching between lean and rich feeds, the LNT layer reduced NOx to N2 and NH3. The SCR layer trapped the latter leading to additional NOx reduction. The dual-layer catalysts exhibited high N2 selectivity and low NH3 selectivity over the temperature range of 150-400 oC. The NOx conversion was incomplete due to undesired NH3 oxidation. The dual-layer catalyst has a higher NOx conversion and N2 selectivity than the LNT catalyst when H2O and CO2 were present in the feed. Ceria was used to adjust the dual-layer catalyst performance. The ceria addition increased NOx storage capacity, promoted hydrothermal durability and mitigated CO poisoning. However, ceria decreased the high-temperature NOx conversion by promoting NH3 oxidation. Ceria zoning led to the highest NOx reduction for both low- and high- temperatures due to the beneficial interaction of ceria and H2. The impact of catalyst design and operation strategy was evaluated. The low-temperature NOx conversion of an aged dual-layer catalyst was increased by a high SCR catalyst loading. The ratio of lean to rich feed duration and the total cycle time were optimized to improve the NOx conversion. The results suggest the dual-layer catalyst could be used to reduce precious metal loading and improve the fuel economy.

Download or read book OXYGEN ENHANCED COMBUSTION FOR NOx CONTROL. written by and published by . This book was released on 2004 with total page pages. Available in PDF, EPUB and Kindle. Book excerpt: Conventional wisdom says adding oxygen to a combustion system enhances product throughput, system efficiency, and, unless special care is taken, increases NOx emissions. This increase in NOx emissions is typically due to elevated flame temperatures associated with oxygen use leading to added thermal NOx formation. Innovative low flame temperature oxy-fuel burner designs have been developed and commercialized to minimize both thermal and fuel NOx formation for gas and oil fired industrial furnaces. To be effective these systems require close to 100% oxy-fuel combustion and the cost of oxygen is paid for by fuel savings and other benefits. For applications to coal-fired utility boilers at the current cost of oxygen, however, it is not economically feasible to use 100% oxygen for NOx control. In spite of this conventional wisdom, Praxair and its team members, in partnership with the US Department of Energy National Energy Technology Laboratory, have developed a novel way to use oxygen to reduce NOx emissions without resorting to complete oxy-fuel conversion. In this concept oxygen is added to the combustion process to enhance operation of a low NOx combustion system. Only a small fraction of combustion air is replaced with oxygen in the process. By selectively adding oxygen to a low NOx combustion system it is possible to reduce NOx emissions from nitrogen-containing fuels, including pulverized coal, while improving combustion characteristics such as unburned carbon. A combination of experimental work and modeling was used to define how well oxygen enhanced combustion could reduce NOx emissions. The results of this work suggest that small amounts of oxygen replacement can reduce the NOx emissions as compared to the air-alone system. NOx emissions significantly below 0.15 lbs/MMBtu were measured. Oxygen addition was also shown to reduce carbon in ash. Comparison of the costs of using oxygen for NOx control against competing technologies, such as SCR, show that this concept offers substantial savings over SCR and is an economically attractive alternative to purchasing NOx credits or installing other conventional technologies. In conjunction with the development of oxygen based low NOx technology, Praxair also worked on developing the economically enhancing oxygen transport membrane (OTM) technology which is ideally suited for integration with combustion systems to achieve further significant cost reductions and efficiency improvements. This OTM oxygen production technology is based on ceramic mixed conductor membranes that operate at high temperatures and can be operated in a pressure driven mode to separate oxygen with infinite selectivity and high flux. An OTM material was selected and characterized. OTM elements were successfully fabricated. A single tube OTM reactor was designed and assembled. Testing of dense OTM elements was conducted with promising oxygen flux results of 100% of target flux. However, based on current natural gas prices and stand-alone air separation processes, ceramic membranes do not offer an economic advantage for this application. Under a different DOE-NETL Cooperative Agreement, Praxair is continuing to develop oxygen transport membranes for the Advanced Boiler where the economics appear more attractive.
