摘要： The present invention relates to a fluid-bed catalyst for the preparation of ethylene and propylene by catalytic cracking. The main technical problems to be solved are a relatively high reaction temperature, and low activities and poor selectivities of the catalyst at a low temperature, during the reaction for preparing ethylene and propylene by catalytically cracking naphtha. The technical solution of the catalyst is a composition of the chemical formula Mo1.0VaAbBcCdOX based on stoichiometric ratio. It has satisfactorily solved the above-mentioned problems, and is useful in the industrial production of ethylene and propylene by catalytically cracking naphtha.
