The role of the resid solvent in coprocessing with finely divided catalysts. Quarterly report, July--September, 1994
This progress report describes the continuation of coal-resid coprocessing reactions which have been performed during the last two quarters. During the past two quarters, Maya and FHC-623 resids were evaluated as whole resids and as the hexane soluble fractions in noncatalytic and catalytic reactions at 400 C with Pittsburgh No. 8 bituminous coal and Blind Canyon bituminous coal. During this current quarter, reactions have been performed with the saturate fraction of these resids. In order to evaluate the role of the different components in resids, the hexane fractions of the resids were separated into saturate and aromatic fractions. The saturate fraction should contain the majority of the naphthenes present in the resid. The saturate fractions were reacted with coal at the same liquefaction conditions as the whole resids and the hexane soluble fractions of the resid. In the catalytic reactions, a Mo naphthenate precursor was used in the presence of sulfur. The catalyst generate din situ was MoS{sub 2}. 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 resid solvent system and catalytic treatment on coal behavior during liquefaction was determined by the amount of coal conversion to THF solubles and solvent fractionation of the reaction products.
