Book excerpt: The research reported in this progress report describes the continuation of coal-resid coprocessing reactions which were begun last quarter (October to December 1993). During, last quarter, Maya and FHC-623 resid were evaluated as whole resids and as the hexane soluble fraction in noncatalytic and catalytic reactions at 400°C. During this current quarter, reactions were performed using Pittsburgh No. 8 bituminous coal and several different solvents including Maya and FHC-623 resids. In order to evaluate the role of the different components in resids, the resids were separated into hexane soluble materials and hexane insoluble materials. The hexane solubles, which should contain the naphthene present in the resid, and the untreated whole resids were reacted with coal at the same liquefaction conditions as when the resids were reacted individually. In the catalytic reactions, a Mo naphthenate precursor was used in the presence of sulfur. The catalyst generated in situ was MoS2 . The effect of different reaction conditions on the resid was monitored by gas chromatography in which the retention times of the eluting peaks were determined. The amount of eluent present at different retention times was determined and compared. The effect of the reaction system on coal behavior during liquefaction was determined by coal conversion to THF solubles and solvent fractionation of the reaction products.
