Abstract:
A process for hydroisomerizing the slurry hydrocarbon liquid produced in a slurry hydrocarbon synthesis reactor in said reactor while it is producing said liquid from a synthesis gas and wherein said slurry in said synthesis reactor is a slurry body comprising gas bubbles and catalyst particles in said liquid, said process comprising:(a) contacting a portion of said slurry from said slurry body with means for removing gas bubbles, to produce a gas bubble reduced slurry; (b) passing a hydrogen treat gas and said gas bubble reduced slurry into and up through a hydroisomerization zone in one or more lift reactors in said synthesis reactor which are at least partially immersed in said slurry body therein, with each said lift reactor containing a hydroisomerization catalyst therein which defines a hydroisomerization zone; (c) reacting said gas bubble reduced slurry and hydrogen in the presence of said hydroisomerization catalyst, at reaction conditions effective to hydroisomerize at least a portion of said liquid and produce a hydroisomerized liquid, and (d) passing all or a portion of said hydroisomerized hydrocarbon liquid back into said slurry body.
