Title: Developmental research program for clean industrial and transportation fuels from coal

Abstract

The integrated coal liquefaction facility was operated to first demonstrate solvent self-sufficiency on equilibrium paste solvent. A coal paste consisting of 70 weight percent hydrogenated start-up paste oil and 30 weight percent coal was used to generate an initial solvent inventory. This paste oil pool was then used for all subsequent operations. Solvent self-sufficiency on equilibrium solvent as monitored by a combination of elemental analyses, physical properties, analytical distillations, and spectrophotometric measurements was demonstrated. With equilibrium paste solvent available, a catalyst life study was initiated and completed. Operations on catalyst life testing were concluded at the request of DOE at a coal throughput of 1,567 pounds of coal per pound of catalysts. The sulfur, nitrogen, and ash results for operations at a throughput of just over 1200 pounds of coal per pound of catalyst are listed. When employing a catalyst replacement mode of operation, the projected results indicate that a nitrogen level of 0.5 weight percent would permit the processing of 1,653 pounds of coal per pound of catalyst equivalent to a catalyst consumption of 1.21 pounds of catalyst per ton of coal. Nitrogen levels are controlling, since a sulfur level of 0.3 weight percent (with catalyst replacement) would permitmore » a throughput of 6,010 pounds of coal per pound of catalyst - a catalyst consumption of 0.33 pounds per ton of coal. Confirming the anticipated benefits of operating the hydroliquefaction reactors in a manner approaching plug flow, the hydrogen consumptions during the catalyst life study period ranged from 2.3 to 3.1 weight percent on coal for the yield structures reported herein.« less
