Abstract
The present invention relates to an integrated fluid coking/hydrogen production process. The fluid coking unit is comprised of a fluid coker reactor, a heater, and a gasifier. Solids from the fluidized beds are recycled between the coking zone and the heater and between the heater and the gasifier. A separate stream of hot solids from the gasifier is passed to the scrubbing zone of the reactor. Methane and steam are introduced into the stream of hot solids passing from the gasifier to the scrubbing zone. The hot particles act to catalyze the conversion of methane to carbon monoxide and hydrogen in the presence of steam.
