ABSTRACT:
A process for the conversion of heavy hydrocarbon feedstocks which are characterized by high molecular weight, low reactivity and high metal contents comprising feeding the feedstock to a hydrodemetallization zone where the feedstock is contacted with hydrogen and a catalyst capable of demetallizing organometallic complexes of high molecular weight and cracking resistance, thereafter removing the effluent from the demetallization zone and feeding same to the thermal cracking zone where the effluent is contacted with hydrogen and thereafter feeding the product from the cracking zone to a hydrocarbon conversion zone where the product is contacted with hydrogen and a catalyst capable of cracking molecules of high cracking resistance.
