Bench-scale co-processing

Description: The objective of this contract is to extend and optimize UOP's single-stage, slurry-catalyzed co-processing scheme. The particular emphasis is one evaluating alternative and disposable slurry-catalyst systems. During the current quarter, Lloydminster vacuum resid was processed without the presence of coal. The objective of this study was to evaluate the manner in which the resid is upgraded at high-severity conditions to help understand the function of the resid during co-processing. This repor… more

Fluidized-bed copper oxide process

Description: The fluidized-bed copper oxide process was developed to simultaneously remove sulfur dioxide and nitrogen oxide contaminants from the flue gas of coal-fired utility boilers. This dry and regenerable process uses a copper oxide sorbent in a fluidized-bed reactor. Contaminants are removed without generating waste material. (VC)

Bench-scale co-processing

Description: The objective of this contract is to extend and optimize UOP's single-stage, slurry-catalyzed co-processing scheme. The current task is to complete a long-term operability run using a 0.05 wt-% Mo-based catalyst at approximately 460{degrees}C. The objectives of this run are to demonstrate that high-severity conditions can be run for an extended period of time (at least one month) and to collect enough product sample to do a complete Hempel fractionation and detailed characterization of the indi… more

Development of a stable cobalt-ruthenium Fischer-Tropsch catalyst

Description: The work performed in the program suggests that cobalt catalytic performance is a complex function of crystallite size, crystallite composition, and cobalt-support interaction. These properties are determined by the nature of support, the bimetallic component, the promoters, and the method of preparation. Results so far indicate that the lowest methane selectivity occurs on support No. 8, and the highest activity is obtained on support No. 10. Also, promoters 2 and 3 may help lower the formatio… more

Development of a stable cobalt-ruthenium Fischer-Tropsch catalyst. Technical progress report No. 13, October 1, 1992--December 31, 1992

Description: Four new catalysts (No. 6531-194, -196, -202, and -204) were prepared using steamed, acid-washed Y-zeolite as support. Two batches of support were used, each prepared by extensive acid-washing of the steamed Y-zeolite. X-ray analysis (Table 2) of the acid-washed supports suggests that crystallinity of the steamed Y-zeolite is destroyed during the acid washing. These supports can be best described as amorphous silica. Three of the four catalysts (No. 6531-196,- 202, and -204) contained ruthenium… more

[Oxygenated octane enhancers: Syngas to isobutylene]. Technical progress report No. 8, January 1, 1993--March 31, 1993

Description: The goal of this program is to develop a catalyst and a process for the conversion of syngas to isobutylene. However, due to the low conversion and selectivity generally experienced by the industry in direct conversion of syngas to isobutylene, indirect conversion via branched C{sub 4} alcohol intermediates is being explored. The objectives of the current program are to develop a catalyst and process for the conversion of syngas to isobutanol and to evaluate the commercial potential of the new … more

Development of a catalyst for conversion of syngas-derived materials to isobutylene. Technical progress report No. 6, July 1, 1992--September 30, 1992

Description: Goal is to develop a catalyst and technology that will produce iC{sub 4}{double_bond} directly from coal-derived syngas and that is capable of using a lower H{sub 2}/CO ratio (0.5 to 1.0). This report covers the testing of various zirconia (ZrO{sub 2}) based catalyst systems designed to examine effects of catalyst preparation and process variables, especially feed additives. Testing sol-gel ZrO{sub 2} catalysts calcined at 475 C instead of 500 C increases the isobutene yield. Supporting zirconi… more
