Abstract

1499332 Destructive hydrogenation GULF OIL CORP 25 June 1974 [4 March 1974] 28160/74 Heading C5E Deashed solid and liquid fuels are made from coal by contacting the coal (10) with hydrogen (40) and an incompletely hydrogenated hydroaromatic solvent (14) to form a slurry (16) in contact with hydrogen, passing the slurry through a preheater (18) that has a ratio of length to diameter of at least 100, so as to inhibit backmixing, for a residence time between 0À01 and 0À25 hours and so that the relative viscosity, which first rises to at least 20, then falls below 10 and finally begins to rise again, has not yet risen the second time beyond 10, to an outlet temperature of 400 to 525‹ C., cooling the slurry by at least 10‹ C., e.g. by adding cool makeup hydrogen at 12, to prevent a further rise in relative viscosity, passing the slurry to a dissolver (24) and holding it there, with mixing, for a time longer than in the preheater, but at a lower temperature between 350‹ C. and 475‹ C., removing the slurry from the dissolver, separating it into a gaseous fraction (30), a liquid fuel product (42) and a deashed solid fuel product (46), and recycling the hydrogen and part of the liquid fuel. A mixture of carbonic oxide and steam may be used in place of hydrogen. The ash precursors in the raw coal act as catalysts; no other catalyst is added.
