Abstract
A
cracking catalyst for the production of light olefins
comprises 0-70% (based on the weight of the catalyst)
of clay, 5-99% of inorganic oxides, and 1-50% of zeolite.
The zeolite in the catalyst is a mixture of 0-25wt% of
REY or high silica Y zeolite and 75-100 wt% of phosphorus
and rare earth containing high silica zeolite having a
structure of pentasil. The catalyst exhibits higher hydrothermal
activity-stability, conversion level, and C2-C4
olefin yields in cracking reaction, comparing with the
catalyst using HZSM-5 zeolite as active component.
