PROCESS FOR CONVERTING ALIPHATICS TO AROMATICS OVER A GALLIUM-CONTAINING ZEOLITE

摘要

A catalytic process is provided for converting a feedstock containing C3 to C12 aliphatic hydrocarbons to aromatics by contacting the feedstock under conversion conditions with a catalyst prepared by loading with gallium a zeolite having a Constraint Index within the approximate range of 1 to 12 and a silica/alumina molar ratio of about 25:1 to 1000:1, and subsequently calcining the catalyst at a temperature of at least about 700 DEG C.
