Quarterly Technical Progress Report Number 17, September 1, 1995--December 31, 1995 written by and published by . This book was released on 1996 with total page 25 pages. Available in PDF, EPUB and Kindle. Book excerpt: During this reporting period, there were three major thrusts in the WVU portion. First, we started a preliminary investigation on the use of a membrane reactor for HAS. Accordingly, the plug-flow reactor which had been isolated from sulfides was substituted by a membrane reactor. The tubular membrane was first characterized in terms of its permeation properties, i.e., the fluxes, permeances and selectivities of the components. After that, a BASF methanol-synthesis catalyst was tested under different conditions on the membrane reactor. The results will be compared with those from a non-permeable stainless steel tubular reactor under the same conditions. Second, we started a detailed study of one of the catalysts tested during the screening runs. Accordingly, a carbon-supported potassium-doped molybdenum-cobalt catalyst was selected to be run in the Rotoberty reactor. Finally, we have started detailed analyses of reaction products from some earlier screening runs in which non-sulfide molybdenum-based catalysts were employed and much more complicated product distributions were generally observed. These products could not hitherto be analyzed using the gas chromatograph which was then available. A Varian gas chromatograph/mass spectrometer (GC/MS) is being used to characterize these liquid products. At UCC, we completed a screening of an Engelhard support impregnated with copper and cesium. We have met or exceeded three of four catalyst development targets. Oxygenate selectivity is our main hurdle. Further, we tested the effect of replacing stainless-steel reactor preheater tubing and fittings with titanium ones. We had hoped to reduce the yield of hydrocarbons which may have been produced at high temperatures due to Fischer-Tropsch catalysis with the iron and nickel in the preheater tube walls. Results showed that total hydrocarbon space time yield was actually increased with the titanium preheater, while total alcohol space time yield was not significantly affected.

Download or read book Technology Development for Iron Fischer-Tropsch Catalysis. Quarterly Technical Progress Report No. 5, October 1, 1995--December 31, 1995 written by and published by . This book was released on 1996 with total page 39 pages. Available in PDF, EPUB and Kindle. Book excerpt: The objective of this research project is to develop the technology for the production of physically robust iron-based Fischer-Tropsch catalysts that have suitable activity, selectivity and stability to be used in the slurry phase synthesis reactor development. The catalysts that are developed shall be suitable for testing in the Advanced Fuels Development Facility at LaPorte, Texas, to produce either low- or high-alpha product distributions. Previous work by the offeror has produced a catalyst formulation that is 1.5 times as active as the ''standard-catalyst'' developed by German workers for slurry phase synthesis. The proposed work will optimize the catalyst composition and pretreatment operation for this low-alpha catalyst. In parallel, work will be conducted to design a high-alpha iron catalyst this is suitable for slurry phase synthesis. Studies will be conducted to define the chemical phases present at various stages of the pretreatment and synthesis stages and to define the course of these changes. The oxidation/reduction cycles that are anticipated to occur in large, commercial reactors will be studied at the laboratory scale. Catalyst performance will be determined for catalysts synthesized in this program for activity, selectivity and aging characteristics. The research is divided into four major topical areas: (a) catalyst preparation and characterization, (b) product characterization, (c) reactor operations, and (d) data assessment. Accomplishments to date are described.

Available in PDF, EPUB and Kindle. Book excerpt: Several new initiatives were begun in coal preparation, including a project to develop a liquid CO2 coalescence process that will produce a superclean coal containing less than 1% ash. Another new project in this area is focusing on chemical coal cleaning for the removal of harmful trace elements, such as arsenic, lead, and zinc. Milestones were reached in both of our major electron beam flue gas cleanup projects. In the area of coal-water mixtures, our major industrial contracts are now approaching critical milestones. The analysis of our in-house combustion testing of micronized coal-water mixtures in PETC's 700-horsepower oil-designed boiler has been completed. By reducing the coal particle size from 90% minus 200 mesh down to 87% minus 19 microns, the carbon conversion efficiency increased from a level of 96% to 98%. Combustion tests with a commercially available CWM showed that combustion air enriched to 23% oxygen reduced the needed air preheat temperature from 370° to 200°F. Work also got underway in the new projects selected last summer to investigate advanced direct liquefaction processes. At Kerr-McGee, three scoping runs on their 350 pound/day integrated bench-scale unit were successfully completed. The objective of these runs was to evaluate subbituminous coal process options in terms of catalyst performance, distillate yields, and generation of coke precursors. Cities Service began its project on the characterization of hydrogen donor solvents in two-stage liquefaction. 7 figures, 33 tables.

Download or read book Computational Modeling and Experimental Studies on NO(subscript X) Reduction Under Pulverized Coal Combustion Conditions. Technical Progress Report, Second Quarter, April 1, 1995--June 30, 1995 written by and published by . This book was released on 1995 with total page 25 pages. Available in PDF, EPUB and Kindle. Book excerpt: Presented in this second quarterly report are the computational results of NO reburning with (a) a combination of methane and acetylene (i) with the reaction mechanism listed in the first quarterly report and (ii) with the updated reaction mechanism (Table 1 of this report); and (b) a combination of methane and ammonia. The impact of the updated reaction scheme was not significant on the results of NO reburning with methane/acetylene; however, the reaction scheme needed changes to improve the accuracy of some reactions of crucial intermediates in methane/ammonia reburning. An extensive literature survey was made in order to update the mechanism.

This book was released on 1994 with total page 32 pages. Available in PDF, EPUB and Kindle. Book excerpt: In this quarterly technical progress report, UTSI reports on progress in developing the technology for the steam bottoming portion of the MHD Steam Combined Cycle power plant. The experimental program was effectively terminated and reoriented to preparation of reports on previous tests and maintaining the DOE facility. In this report, the results of tube corrosion studies for the samples removed after 500 hours of western coal testing are summarized. Plans for evaluating the tube samples after termination of the tests at 1,047 hours are discussed. The status of development of models to predict ash deposition on conductive heat transfer tubes and their validation with experimental data is presented. Modeling and experiments to induce agglomeration of particulate are also discussed. Significant accomplishments, findings and conclusions include: In summary, corrosion measurements on typical, commercial stainless steels and on low and intermediate chromium steels after 639 hours of LMF5 exposure in the SHTM test sections revealed corrosion that was generally acceptable in magnitude if corrosion kinetics are parabolic, but, except for the higher chromium alloys 253MA and 310, not if kinetics are linear. The production of bilayer scales, and the large amount of scale separation and fragmentation make long term parabolic kinetics unlikely, and result in a high likelihood for breakaway corrosion.

Available in PDF, EPUB and Kindle. Book excerpt: The objective of the Fuel Quality Advisor (FQA) project is to create a generalized software package capable of advising operations, purchasing, environmental, and maintenance personnel in making decisions related to the use of coal in electricity generation facilities. The specific goals for this years work include the following: develop a standardized computer shell to integrate existing and future algorithms; develop a strategy for integrating the shell with future databases and boiler models; integrate the current ash transformations and deposition algorithms into the shell; generate algorithms for coal handleability through experimentation and integrate them into the code; and enhance the current ash transformation algorithms for low-NOx and entrained gasification through laboratory experimentation and integrate available full-scale results into the code. The program is divided into three primary thrust areas: development of computerized shell and interface, development of coal handleability advisor, and enhancement of ash formation algorithms. The progress in each of these three areas over the last 6 months is described in detail.
