ABSTRACT:
In the thermal cracking of a hydrocarbon feed oil to produce a product including ethylene, the feed oil is passed together with entrained hot solids through a high temperature cracking zone. Coke-laden hot solids are recovered and passed to a burner zone together with crushed oil shale as supplementary fuel. An acidic material, such as HF catalyst from an alkylation unit, can also be employed as supplementary fuel. The acidic material will react with alkaline components in the oil shale to form stable neutral salts which circulate as heat carrier solids.
