Results of process development units have demonstrated that the integrated two stage liquefaction process is capable of achieving both greater yields of distillate products and higher product quality than other direct liquefaction processes. Illinois No. 6 and Indiana V exhibited minor differences in reactivity in the short contact time reaction (SCT) while Illinois No. 6 is a more reactive feed to the LC-Finer. The effect of the recycle solvent on the SCT reaction and hydrogen consumption efficiency for the overall process have been confirmed from material and elemental balances around each unit. The recycle solvent contributes to the SCT reaction by donating hydrogen which is replenished in the LC-Finding stage. Hydroliquefaction of coal by the efficient transfer of hydrogen enables the SCT reaction to be run at relatively mild conditions, minimizing external gas consumption and the yield of undesirable thermal products. By shifting nearly all of the distillate production to a lower temperature, catalytic LC-Fining reaction, overall gas yields are minimized and distillate yields are maximized, resulting in a hydrogen utilization efficiency which is close to the theoretical maximum. 9 figures, 16 tables.
