Description

ABSTRACT Novel fuel compositions comprising: (A) a solid and/or semi-solid material formed by a process for upgrading coal which comprises the steps of: (1) subjecting a slurry composed of coal and a solvent containing donatable hydrogen, together with hydro- gen, to catalyst-free hydrogenation conditions in a first hydro- genation zone to form an intermediate coal-solvent slurry (2) deashing said intermediate coal-solvent slurry to first a coal- solvent solution; (3) subjecting said coal-solvent solution to catalytic hydrogenation conditions in a second hydrogenation zone to obtain a product that can be separated at ambient pressure into (a) a first liquid fraction boiling at a temperature in the range of about 100 to about 375°C, (b) a second liquid fraction boiling above said first liquid fraction at a temperature in the range of about 200 to about 525°C and (c) said solid and/or semi-solid material; and then (4) recycling at least a portion of said second liquid fraction to said first hydrogenation zone, and (B) a light- boiling hydrocarbon stock boiling at a temperature in the range of about 100 to about 375°C at ambient pressure; wherein the weight ratio of said solid and/or semi-solid material to said light-boiling hydrocarbon stock is about 20:1 to about 1.5:1.
