Fundamental Reaction Pathways During Coprocessing

Description: The objective of this research was to investigate the fundamental reaction pathways in coal petroleum residuum coprocessing. Once the reaction pathways are defined, further efforts can be directed at improving those aspects of the chemistry of coprocessing that are responsible for the desired results such as high oil yields, low dihydrogen consumption, and mild reaction conditions. We decided to carry out this investigation by looking at four basic aspects of coprocessing: (1) the effect of fos… more

Bench-scale co-processing. Quarterly report No. 11, October 1, 1990--December 31, 1990

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

Bench-scale co-processing. Technical progress report No. 23, January 1, 1994--March 31, 1994

Description: UOP`s second co-processing contract, DE-AC22-87PC79818, began in April 1988. The major objective of this contract is to establish a database for the optimization of the co-processing concept by improving the effectiveness of the co-processing catalyst system. Two major mechanisms for improving the catalyst system are to be investigated: employment of more effective catalysts and utilization of improved catalytic environments. These two mechanisms are defined in the contract Statement of Work. W… more

Bench-scale co-processing. Quarterly report No. 13, April 1, 1991--September 31, 1991

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

Bench-scale co-processing. Quarterly report No. 16, April 1, 1992--June 30, 1992

Description: The high-severity co-processing long-term operability test and the detailed product analyses from the operability test have been completed. Operational data and detailed product analyses have been used to characterize the high-severity co-processing operation. Using the process characterizations, yield estimate for a commercial-sized high-severity co-processing unit has been performed using operational data and detailed product analysis from the long-term operability study. The estimate is base… more

Bench-Scale Co-Processing

Description: This topical report is the first for the UOP Bench-Scale Co-processing contract. The objective of this contract is to extend and optimize the UOP single-stage, slurry-catalyzed co-processing scheme. UOP co-processing uses a single-stage, slurry-catalyzed scheme in which petroleum vacuum resid and coal are simultaneously upgraded to a high-quality synthetic oil. A highly active, well-dispersed catalyst permits operations at moderate- and high-severity reaction conditions with minimum detrimental… more

Bench-scale co-processing. Quarterly report No. 9, March 1, 1990--June 31, 1990

Description: This is the ninth quarterly report. Objective is to extend and optimize UOP`s single-stage slurry-catalyzed co-processing scheme. Emphasis is given to defining and improving catalyst utilization and costs, evaluating alternative and disposable slurry-catalyst systems, and improving catalyst recycle and recovery. During this quarter, a temperature survey was completed with the reference V catalyst and liquid recycle. Objective of this study was to determine whether the improved high-severity per… more

Bench-scale co-processing, Technical progress report No. 21, July 1, 1993--September 30, 1993

Description: Objective is to establish a database for optimizing the co-processing concept by improving the effectiveness of the co-processing catalyst system. Two major mechanisms for improving the catalyst system are to be investigated: more effective catalysts (subtask 3.2.1) and improved catalytic environments (3.2.2). During this period, work on 3.2.2 was carried out and the bench-scale co-processing pilot plant was operated in the counter-current mode. The counter-current process in presence and absen… more
