Process for syngas conversions to liquid hydrocarbon products utilizing zeolite Beta

Claim 1

Aprocess for converting synthesis gas to liquid hydrocarbons having a boiling range within that of gasoline and distillate comprising the steps of: (a) charging said synthesis gas to a Fischer-Tropsch synthesis conversion zone comprising a catalyst providing CO reducing characteristics in a single form or a combination of catalyst particles in direct contact with a suspending liquid medium; (b) separating at least a fraction of said suspending liquid medium containing dissolved heavier hydrocarbons from said catalyst particles; (c) contacting said separated suspending medium containing heavier hydrocarbons in a cracking zone with a cracking and isomerization catalyst comprising zeolite Beta under conditions effective to crack and isomerize at least a portion of said heavier hydrocarbons to lighter hydrocarbons; (d) separating the resultant product stream of (c) into two streams; (e) removing an effluent stream from said conversion zone of (a) to a second reaction zone containing a crystalline zeolite catalyst; (f) returning one of said streams of (d) to said effluent stream from zone (a); (g) returning the remaining stream of (d) to said conversion zone of (a); and (h) contacting said effluent stream from said conversion zone of (a) with a crystalline zeolite to convert the product of said Fischer-Tropsch synthesis gas conversion to hydrocarbons boiling within the range of distillate and gasoline.
