The synthesis method and catalyst for methylchloride to light olefins

摘要

The invention chloromethane (methylchloride, CH ₃ Cl) a silico-alumino-phosphate (SAPO) minutes The manufacturing method of light olefins (light olefins) which comprises contacting with itself and relates to a catalyst used therein, the catalyst is silica to alumina (Si / Al) molar ratio is 0.01 ~ 0.7, and surface-treated by silica, and a silico-alumino-phosphate (SAPO) minutes, the characterized in that the content of 1 to 10% by weight of carbonaceous materials deposited in itself, the present invention can be manufactured in high yield and selectivity to light olefins by using chloromethane. ; Chloromethane (methylchloride), ethylene (ethylene), the propylene (propylene), MTO (Methanol to Olefins), SAPO-34
