Abstract:
1. Process for catalytic cracking of hydrocarbons for production of light olefins, characterized in that it comprises contacting a feed comprising saturated hydrocarbons, with molecular size in the range from 4 to 6 carbon atoms, and a catalyst comprising a zeolite of type ZSM-5 modified with nickel, having a concentration by weight of nickel, expressed in the form of oxide, of from 0.4% to 1.0% relative to the weight of zeolites, under conditions for cracking at a temperature from 400° C. to 600° C., feed partial pressure from 0.1 to 1.0 MPa, and contact time from 0.01 to 0.5 seconds, catalyst/feed ratio less than 2.0, recovering a product enriched in olefins, with degree of selectivity C2 = /C3 = from 0.25 to 2.00.
