Title:
接触分解によるエチレンおよびプロピレン製造のための流動層触媒
Document Type and Number:
Japanese Patent JP5465822
Kind Code:
B2
Abstract:
A method for preparation of ethylene and propylene by catalytic cracking using a fluid-bed catalyst. 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 fluid-bed catalyst is a composition of the chemical formula Mo1.0VaAbBcCdOx based on stoichiometric ratio. The method using the fluid-bed catalyst has satisfactorily solved the above-mentioned problems, and is useful in the industrial production of ethylene and propylene by catalytically cracking naphtha.
