A HIGH PRODUCTIVE PROCESS FOR PRODUCTION OF LOWER OLEFINS BY CATALYTIC CONVERSION |
摘要 |
<p>A process for producing light olefins, especially ethylene, propylene,isobutylene and isoamylene, together with high octane gasoline as by-product, comprises that petroleum hydrocarbons are contacted with phosphorus and rare earth containing high silica zeolite having a structure of pentasil catalysts and catalytically converted at a temperature of 480 DEG to 680 DEG C and a pressure of 1.2x10<5> to 4.0x10<5>Pa, with a contact time of 0.1 to 6 seconds, a weight ratio of catalyst to feedstock of 4:1 to 20:1 and a weight ratio of steam to feedstock of 0.01:1 to 0.5:1.</p> |
