The invention relates to a method for preparing ethylene and propylene form oxides, which mainly solves the problems in the prior art, such as low selectivity and low yield of ethylene and propylene. The invention uses oxides as materials, the materials pass through a catalyst bed layer to generate an effluent containing ethylene and propylene, the catalyst uses a carrier selected from at least one of SiO2, AL2O3, molecular sieve or compound molecular sieve, and contains a composition Mo1.0VaAbBcCdOx based on the atom ratio. In this way, the invention solves the problems well, and is useful in industrial production of ethylene and propylene from oxide catalyst schizolysis.
Description
Process for producing ethylene and propylene from oxygenated compounds technical field The invention relates to a method for producing ethylene and propylene from oxygen-containing compounds, in particular to a method for producing ethylene and propylene through the catalytic conversion of oxygen-containing compounds such as methanol or / and dimethyl ether. Background technique Petrochemical industry is an important pillar industry in the national economy. It provides a large amount of chemical raw materials for industry, agriculture, transportation and national defense. It is one of the most relevant and leading industrial sectors in the national economy. Propylene and ethylene are the two most important basic raw materials for modern petrochemical industry. The bulk downstream products of ethylene mainly include polyethylene, ethylene oxide, ethylene glycol, polyvinyl chloride, styrene, vinyl acetate, etc. The size of ethylene production is a sign to measure the degree ...
