WebDec 12, 2016 · Cat cracking produces a full range of hydrocarbons, from methane to residue. The feed to the cat cracker is typically gas oil or naphtha. The trend in the design of modern cracking units is the ability to include the residuum as a part of the cracker feed. The residue produced by the catalytic cracker is recycled back into the feed stream.
