Abstract
Abstract A process for the gasification of oil containing finely dispersed solids, e.g., oil from tar sands, by partial combustion in a hollow reactor is disclosed in which process the gaseous oxidant is introduced into the reactor under flow conditions characterized by a relatively large axial velocity component as compared with the tangential flow component resulting in a relatively long flame.

Claims Analysis
Total Claims: 8
Claim 1
Independent Claim
101 words
In the process for the partial combustion of a liquid hydrocarbon fuel containing finely dispersed solids in a substantially void reactor wherein the fuel is mixed with or finely dispersed in an oxygen-containing gas and passed as a gaseous jet through at least one supply opening in the reactor and wherein said oxygen-containing gas is introduced into said reactor with a tangential as well as axial velocity component, the improvement wherein the ratio of the axial velocity component (V ax ) of the oxygen-containing gas as compared to the tangential velocity component (V tan ) of the oxygen-containing gas exceeds 3.0.
Claim 2
Dependent Claim
101 words
In the process for the partial combustion of a liquid hydrocarbon fuel containing finely dispersed solids in a substantially void reactor wherein the fuel is mixed with or finely dispersed in an oxygen-containing gas and passed as a gaseous jet through at least one supply opening in the reactor and wherein said oxygen-containing gas is introduced into said reactor with a tangential as well as axial velocity component, the improvement wherein the ratio of the axial velocity component (V ax ) of the oxygen-containing gas as compared to the tangential velocity component (V tan ) of the oxygen-containing gas exceeds 3.0.
Claim 3
Dependent Claim
21 words
A process according to claim 1 wherein the weight percent of finely dispersed solids in said liquid hydrocarbon fuel exceeds 0.1%.
Claim 4
Dependent Claim
22 words
A process according to claim 2 wherein said liquid hydrocarbon fuel is a petroleum fraction obtained from the processing of tar sands.
Claim 5
Dependent Claim
26 words
A process according to claim 3 wherein the weight percent of finely dispersed solids in said liquid hydrocarbon fuel is between about 0.5 and 5.0% weight.
Claim 6
Dependent Claim
22 words
A process according to claim 4 wherein the ratio of V ax to V tan is between about 4.0 and about 5.0.
Claim 7
Dependent Claim
22 words
A process according to claim 1 wherein the ratio of V ax to V tan is between about 4.0 and about 5.0.
Claim 8
Dependent Claim
13 words
A process according to claim 1 wherein steam is injected into said reactor.
