Abstract
A process for refining coke-forming hydrocarbon distillates comprises contacting a stream of the distillate together with added hydrogen at superatmospheric pressure and a temperature of at least 150 DEG C., and less than 260 DEG C., with a hydrorefining catalyst in a first zone, the effluent from the first zone is heated to a higher temperature and contacted with a hydrorefining catalyst at superatmospheric pressure and a temperature of not more than 427 DEG C., and above 260 DEG C., and the effluent from the second zone is separated into a gaseous stream and a liquid product stream, characterized in that the charge stream prior to its reaction in the first zone is commingled with a portion of the liquid product stream in an amount of from 1 to 5 vols. of liquid product per vol. of fresh charge, and the catalyst in each zone comprises at least one metal from Group VIa and VIII of the Periodic Table supported on a non-acidic refractory inorganic oxide carrier material, for example alumina. The catalyst is preferably molybdenum together with iron, cobalt, or nickel, in the form of their oxides or sulphides. Hydrogen-rich gas separated from the effluent of the second zone may be recycled to the first zone, and fresh hydrogen supplied for make-up, preferably to the effluent from the first zone. Specification 826,305 is referred to.
