METHOD FOR JOINTLY PRODUCING PROPYLENE AND PETROL FROM A RELATIVELY HEAVY CHARGE

摘要

A method for converting a hydrocarbonated charge comprising a relatively heavy charge having a boiling temperature of more than 350 DEG C, and a secondary charge which is relatively light having a boiling temperature of less than 320 DEG C, wherein the main charge is cracked, representing more than 50 % of the weight of the hydrocarbonated charge, in a fluidized bed reactor in the presence of a cracking catalyst; the secondary charge is cracked in a fluidized bed with the same cracking catalyst, either separately or in a mixture with the main charge, said secondary charge comprising oligomers having at least 8 atoms of carbon from light olefins having 4 and/or 5 carbon atoms.
