Solvent refined coal process |
| abstract |
A slurry composed of coal and a solvent containing donatable hydrogen, together with hydrogen, is subjected to catalyst-free hydrogenation conditions in a first hydrogenation zone to form an intermediate coal-solvent slurry. After removing ash from the intermediate coal-solvent slurry to form a coal-solvent solution, the coal-solvent solution is subjected 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 DEG to about 375 DEG C., (b) a second liquid fraction boiling above said first liquid fraction at a temperature in the range of about 200 DEG to about 525 DEG C. and (c) a solid and/or semi-solid material. Following the separation, at least a portion of the second liquid fraction is recycled to the first hydrogenation zone. |
