CATALYTIC CONVERSION OF C 2-6 PARAFFINIC HYDROCARBONS TO AROMATIC HYDROCARBONS

摘要

This invention relates to a process for converting a C2-C6 paraffin feedstock to aromatics over a gallium loaded zeolite catalyst. The feature of the invention is to bring the ethane in the feed with a fresh or freshly regenerated catalyst first and thereafter to bring the residual catalyst from this step into contact with the remainder of the C3-C6 feedstock. The present process has the advantage of maximizing the yields of aromatics from a mixed feedstock using a single reactor and a single charge of catalyst.
