Abstract

An improved fluidized bed coking process wherein a residuum feedstock is introduced into a first stage comprised of a short vapor contact time reactor containing a horizontal moving bed of fluidized hot particles. Carbonaceous material is deposited onto the hot particles on contact with the hot particles, and a vapor product is produced. The hot particles, containing the carbonaceous deposits, are fed to a second stage fluidized bed coking process.
