Abstract
Abstract 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 process can also be operated by yield a net product of good quality coke.

Claims Analysis
Total Claims: 9
Claim 1
Independent Claim
27 words
A process according to claim 1 wherein the pressure in said fluid coking zone, said heating zone and said gasifying zone is less than about 3.0 atmospheres.
Claim 2
Dependent Claim
17 words
A process according to claim 1 wherein said gasifying zone comprises a separate bed of fluidized particles.
Claim 3
Dependent Claim
45 words
A process according to claim 3 wherein said gaseous stream leaving said gasifying zone passes through a distributing zone before entering said heating zone to provide for more even gas flow in said heating zone, as well as, better fluidizing of said heating zone bed.
Claim 4
Dependent Claim
30 words
A process according to claim 4 wherein additional oxygen-containing gases are mixed with said gaseous stream and said mixture passed through said distributing zone and then into said heating zone.
Claim 5
Dependent Claim
47 words
A process according to claim 1 wherein said coke produced in said fluid coking zone is passed through a stripping zone and contacted with a stripping gas to remove a major portion of said adhering light hydrocarbon material before said coke is heated in said heating zone.
Claim 6
Dependent Claim
12 words
A process according to claim 6 wherein said stripping gas is steam.
Claim 7
Dependent Claim
19 words
A process according to claim 1 wherein said metal-rich ash is recovered from said heating zone by cyclone means.
Claim 8
Dependent Claim
19 words
A process according to claim 5 wherein a portion of said metal-rich ash is recovered from said gasifying zone.
Claim 9
Dependent Claim
25 words
A process according to claim 1 wherein a portion of said steam treated, heated coke in said gasifying zone is removed from said gasifying zone.
