US3661543A - Fluid coking process incorporating ...

A heavy carbonaceous material such as petroleum residuum (1,050* F.+) is converted completely to distillate and gaseous products by an integrated process consisting of a conventional fluid coking reactor, a circulating coke heater, and a gasifier in which the coke formed in the reactor is converted to an H2 and CO rich gas by reaction with steam and an oxygen-containing gas.

The Roles of Coal and Coke in Steelmaking

The gases that are produced in the coking process are sent off to a by-product plant, where they are collected for reuse. It is for this reason that the process is called "by-product" coke making. After the coke has cooled, it is ready to go to the blast furnace or it can be stored and shipped to steel mills.
