摘要：The present invention relates to a catalyst for catalytic cracking fluidized-bed, and the technical problems to be primarily solved by the present invention are high reaction temperature, low cryogenic activity of catalysts and worse selectivity during the preparation of ethylene-propylene by catalytically cracking naphtha. The present invention uses the composition having the chemical formula (on the basis of the atom ratio): AaBbPcOx, so as to magnificently solve said problems. The present invention therefore can be industrially used to produce ethylene and propylene by catalytically cracking naphtha.
