SINGLE STAGE PROCESS FOR CONVERTING OXYGENATES TO GASOLINE AND DISTILLATE IN THE PRESENCE OF UNIDIMENSIONAL TEN MEMBER RING ZEOLITE

摘要

A process for selectively converting a feed comprising oxygenate to normally liquid boiling range C5+ hydrocarbons in a single step is provided which comprises a) contacting the feed under oxygenate conversion conditions with a catalyst comprising a unidimensional 10-ring zeolite, e.g., one selected from the group consisting of ZSM-22, ZSM-23, ZSM-35, ZSM-48, ZSM-57, and ferrierite, at temperatures below 350 DEG C and oxygenate pressures above 40 psia (276 kPa); and b) recovering a normally liquid boiling range C5+ hydrocarbons-rich product stream, e.g., gasoline and distillate boiling range hydrocarbons or C4 to C12 olefins.
