PROCESS FOR THE PRODUCTION OF PROPYLENE FROM OLEFINIC STREAMS

摘要

Process for the production of propylene starting from mixtures of hydrocarbons, prevalently olefins, the above hydrocarbons having a boiling point ranging from -15 DEG C to +80 DEG C, preferably from -12 DEG C to +60 DEG C, which comprises putting the above mixture of hydrocarbons in contact, under cracking conditions, with a large-pore zeolite having a molar ratio Silica/Alumina lower than 200, preferably ranging from 50 to 150.
