FLUIDIZED BED CATALYST FOR CATALYTIC PYROLYZING

摘要

Fluidized bed catalyst for catalytic pyrolyzing, which substantially solve the problem of higher reaction temperature, low catalyst activity at low temperature and low selectivity of catalyst during catalytic pyrolyzing naphtha to prepare ethylene and propylene. The present invention preferably solve the said problem by using the subject matter of catalyst which comprise a combination whose formula calculated in atomic ratio is as follows: AaBbPcOx., the catalyst of the invention can be used in the industrial production of catalytic pyrolyzing naphtha to prepare ethylene and propylene.
