  • Patent number: 9234139
    Abstract: A combined Direct Coal Liquefaction (DCL)/Fischer Tropsch (F-T) process and system for producing high Cetane diesel fuel by converting at least 70% of the feed coal by DCL operating at 50 to 70% conversion and gasifying the bottoms and between 0 and 30% of the feed coal to produce H2 for supply to the DCL and to upgrading and syngas for being converted to diesel by F-T. Diesel blendstocks produced by the DCL and the F-T in a ratio of 3 to 1 to 14 to 1 are blended to produce diesel fuel having a Cetane Number of at least 51 and a specific gravity of 0.845 or less.

  • Patent number: 4465584
    Abstract: Coal, petroleum residuum and similar carbonaceous feed materials are subjected to hydroconversion in the presence of molecular hydrogen to produce a hydroconversion effluent which is then subjected to one or more separation steps to remove lower molecular weight liquids and produce a heavy bottoms stream containing high molecular weight liquids and unconverted carbonaceous material. The viscosity of the bottoms streams produced in the separation step or steps is prevented from increasing by treating the feed to the separation step or steps with hydrogen sulfide gas prior to or during the separation step or steps. The viscosity of the heavy bottoms stream produced in the final separation step is also controlled by treating these bottoms with hydrogen sulfide gas.
