Abstract

This program combines a research study on Catalytic Expanded Bed Hydroprocessing of Coal Extracts and the operation of an Integrated Two-Stage Liquefaction Process Development Unit. The integrated operation with Indiana V coal was completed with the conclusion of LC-Fining Run 3LCF7. The first of three 29-day diffusional study runs, PDU Run 4LCF-2, was completed on Shell 324 NiMo 1/32-inch extruded catalyst. The run was made in a new LC-Fining PDU that has three reactors in series and is capable of providing interstage samples between the reactors. Some catalyst deactivation for conversion was detected, but no decline was observed for denitrogenation. Both percent conversion and percent denitrogenation increased with decreasing 850/sup 0/F+ concentration in the feed. LC-Fining Run 3LCF-7 was completed with a final catalyst life of 1070 pounds of 850/sup 0/F+ feed per pound of catalyst. Conversion activity held constant for the entire run while denitrogenation activity declined. The increase of nitrogen in the product was found to be principally in the unconverted 850/sup 0/F+. Approximately 70% of the SCT paste solvent consisted of LC-Fining heavy oil product, including unconverted 850/sup 0/F+. This solvent continued to provide almost all the hydrogen for liquefaction of the Indiana V coal. The hydrogen-transfermore »« less

Technical Report Schindler, H; Chen, J; Potts, J

This program combines a research study on Catalytic Expanded Bed Hydro-processing of Coal Extracts and the operation of an Integrated Two-Stage Liquefaction Process Development Unit. The integrated operation with Illinois No. 6 coal was started and the recycle solvent was brought to equilibrium composition during the course of a 54-day LC-Fining run. The integrated process development unit began operation with the second coal of this program, Illinois No. 6, Burning Star Mine. The severity of the SCT reaction was reduced by lowering the outlet temperature from 865/sup 0/F to 830/sup 0/F, and reducing pressure from 2450 psig to 2000 psig.more »« less
Integrated two stage liquefaction: extract recycle to first stage. Quarterly technical progress report, January 1-March 31, 1981

Technical Report Schindler, H; Chen, J; Potts, J

This program combines a research study on Catalytic Expanded Bed Hydroprocessing of Coal Extracts (Task 1) and the operation of an Integrated Two-Stage Liquefaction process development unit (Task 2). The Task 1 baseline run closely reproduced earlier results obtained with New Brunswick process development units, when operated at similar reaction conditions. However, a two-to three-fold increase in the internal recycle rate increased extract conversion by as much as 20%. The integrated operation of Task 2 continued with equilibrated solvent. Three Short Contact Time (SCT) runs resulted in conversions of 89.7 to 93.8 percent of the moisture, ash-free (MAF) coal feed.more »« less
Integrated two-stage liquefaction. Steady state Illinois No. 6 program. Topical technical progress report, April 1-July 6, 1982

Technical Report Schindler, H; Chen, J; Potts, J

An LC-Fining PDU run indicated that 1/16-inch extruded catalyst has higher activity for 850/sup 0/F+ conversion and denitrogenation than the 1/32-inch extruded catalyst that has been the standard for all LC-Fining work on ITSL. A run with 1/64-inch catalyst was unsuccessful because of high pressure drop through the reactors. The integrated PDU operating with Illinois No. 6 coal and equilibrated solvent was started. LC-Fining activities followed the same trend as reported in the previous Topical Report for Run 3LCF8. The high initial activity for conversion declined and then levelled off at a catalyst age of 300 to 400 pounds ofmore »« less
Integrated two-stage liquefaction. Quarterly technical progress report, October 1, 1980-December 31, 1980: parametric study

Technical Report Schindler, H; Chen, J; Potts, J

This program combines a research study on Catalytic Expanded Bed Hydroprocessing of coal extracts and the operation of an integrated Two-Stage Liquefaction process development unit. Equilibration of the recycle paste solvent was achieved early in this period. Three short contact time (SCT) runs wre made with equilibrium solvent. Conversions ranged from 88 to 95 percent at hydrogen consumptions of 0.41 to 2.40 percent of moisture, ash-free coal. Elemental balances strongly suggest that considerable hydrogen is being transferred from the solvent to the coal. The recycle solvent contained 23 to 48 percent 850/sup 0/F+. The LC-Fining bottoms constitute about 70 percentmore »« less
Integrated two-stage liquefaction: start up of integrated PDU. Quarterly technical progress report, April 1, 1980-June 30, 1980

Technical Report Schindler, H; Chen, J; Potts, J

This program combines a research study on Catalytic Expanded Bed Hydroprocessing of Coal Extracts (Task 1) and the operation of an Integrated Two-Stage Liquefaction Process Development Unit (Task 2). The two tasks are to run con-currently. Two runs of the Parametric study of Task 1 were completed. All units of the Integrated PDU started up with the first stage, the short-contact time reactor, using foreign pasting solvent in this quarter. The parametric Study was interrupted for about one month to replace feed lines, transfer lines and check valves that had become corroded. All Task 2 units were in operation inmore »« less
