Abstract: In a coupled coal solvent liquefaction-gasification system wherein a recycle mineral residue-containing slurry is mixed with the raw coal feed slurry for the liquefaction zone, the resulting feed slurry is under a pumpability total solids level constraint. Where a coupled system is operating under such a total solids level contraint for the feed slurry, any increase in the mineral residue recycle rate relative to the coal feed rate advantageously provides a catalytic activity and selectivity advantage in favor of liquid coal product at the expense of higher and lower boiling products. It is shown herein that this activity and selectivity effect is enhanced with decreasing liquefaction zone residence times. In accordance with the present invention, the ratio of recycle mineral residue to feed coal is enhanced by recycling a second mineral residue-containing slurry to the liquefaction zone independently of the raw coal feed slurry.

Abstract: This invention relates to a combination coal liquefaction-gasification process wherein hydrocarbonaceous mineral residue-containing slurry from the liquefaction zone is recycled to the liquefaction zone and all non-recycled hydrocarbonaceous mineral residue-containing slurry is passed to a gasification zone for conversion to synthesis gas to supply hydrogen for the liquefaction zone. It has now been discovered that in this process a surprisingly high reaction selectivity in favor of the desired distillate oil product is achieved by combining low liquefaction zone residence times and relatively high rates of recycle of mineral residue-containing slurry compared to feed coal rate. Under these conditions the yield of the desired distillate oil product can be increased to an unexpectedly high level while the yields of both higher and lower boiling products are each being decreased and while hydrogen consumption is being reduced.
