Process for cracking paraffins to olefins

摘要

This invention is a process for the catalytic cracking of parafins to produce olefins in high yield while minimizing production of aromatics. The catalyst used is a zeolite in combination with an alkali(ne earth) metal compound wherein the sum of the amount of the alkali(ne earth) metal in the compound plus any metal cation exchanged into the zeolite is in excess of that required to provide a fully metal cation-exchanged zeolite.
