Claims Analysis
Total Claims: 12
Claim 1
Independent Claim
20 words
The process of claim 1 in which the pressure in the partial combustion zone is between 200 and 500 psig.
Claim 2
Dependent Claim
15 words
The process of claim 1 in which the hydrocarbon liquid boils in the naphtha range.
Claim 3
Dependent Claim
20 words
The process of claim 1 in which the temperature in the partial combustion zone is between 2,000* and 2,500* F.
Claim 4
Dependent Claim
14 words
The process of claim 1 in which the cooled product is contacted with N-methYl-pyrrolidone.
Claim 5
Dependent Claim
14 words
The process of claim 1 in which the cooled product is contacted with ethanolamine.
Claim 6
Dependent Claim
14 words
The process of claim 1 in which the cooled product is contacted with methanol.
Claim 7
Dependent Claim
22 words
The process of claim 1 in which the hydrocarbon to air ratio is 0.15 and the hydrocarbon to steam ratio is 6.67.
Claim 8
Dependent Claim
28 words
The process of claim 1 in which the first gas generation zone, the second gas generation zone and the cooling zone are maintained at substantially the same pressure.
Claim 9
Dependent Claim
45 words
The process of claim 1 in which a hydrocarbon oil is fractionated into a light fraction and a heavy fraction and the heavy fraction is used as a scrubbing medium to remove entrained solid particles from the gaseous product of the second gas generation zone.
Claim 10
Dependent Claim
20 words
The process of claim 10 in which the light fraction is introduced as feed to the first gas generation zone.
Claim 11
Dependent Claim
17 words
The process of claim 10 in which the light fraction is injected into the effluent gas stream.
Claim 12
Dependent Claim
21 words
The process of claim 10 in which the heavy fraction-carbon mixture is introduced as feed to the first gas generation zone.
