Abstract: 1316737 Making coke from oil STANDARD OIL CO 17 Sept 1971 [2 Oct 1970] 43464/71 Heading C5E Coker feedstock containing from 0À01 to 1% b.w. solid spent catalyst is coked in a delayed coking process after the catalyst content has been reduced to not more than 0À005% b.w., e.g. by centrifuging or filtration. The feedstock may be decanted oil from a cracking process containing spent silica-alumina cracking catalyst, and the oil may be seeded with particulate colloidal graphite just before being coked. Catalyst fines removed from the oil may be regenerated and recycled to the cracker, and the coke may be calcined, mixed with coal tar pitch, extruded and baked, before being graphitized.
