The results of a series of runs, with a laboratory-scale stirred batch reactor system, and a laboratory-scale continuous flow reactor system, designed to approximate the behavior of a two-step coal hydroliquefaction process, are presented. The results of detailed chemical and physical characterization of the products obtained with a slurry of coal and catalytically hydrogenated tar oil (representing recycle oil), using either a vitrified ceramic, alpha-alumina, or silica for a nominally non-catalytic first-step reactor packing, are presented. Detailed characterization of the products obtained by catalytic hydrogenation of the filtered first-step product in a second-step reactor revealed the effects of the significantly different products obtained from each of the first-step reactor packings. These effects of the product differences on the activity of the second-step catalyst are described. Possible mechanisms for the function of the first-step packings are discussed, as well as the effect of the first-step product on the activity of the cobalt molybdate catalyst in the second-step.
