Abstract
The present invention comprises a process for producing propylene comprising the steps of contacting an olefin feed containing between about 40 and about 80 wt-% olefins and between about 20 and about 60 wt-% olefins and aromatics with a spherical catalyst to form a cracked product, the catalyst comprising about 30 to about 80 wt-% of a crystalline zeolite, the reaction conditions including a temperature from about 500° to 650° C., a hydrocarbon partial pressure of 70 to 280 kPa (10 to 40 psia), a liquid hourly space velocity in the range of 5 to 40 hr−1 and wherein propylene comprises at least 90 mol-% of the total C3 products.
