Claims Analysis
Total Claims: 19
Claim 1
Independent Claim
64 words
A process for reducing the metal, sulfur and nitrogen content of hydrocarbon feedstock which comprises contacting a mixture of hydrocarbon feedstock and hydrogen donor solvent in the absence of added hydrogen and under liquid phase reaction conditions with a catalyst composition comprising a naturally occurring porous metal ore selected from the group consisting of manganese nodules, bog iron, bog manganese, nickel laterites and bauxite.
Claim 2
Dependent Claim
64 words
A process for reducing the metal, sulfur and nitrogen content of hydrocarbon feedstock which comprises contacting a mixture of hydrocarbon feedstock and hydrogen donor solvent in the absence of added hydrogen and under liquid phase reaction conditions with a catalyst composition comprising a naturally occurring porous metal ore selected from the group consisting of manganese nodules, bog iron, bog manganese, nickel laterites and bauxite.
Claim 3
Dependent Claim
98 words
A catalytic process for reducing the metal, sulfur, nitrogen and Conradson Carbon Residue content of a heavy hydrocarbon feedstock which comprises (1) admixing a heavy hydrocarbon oil with a hydrogen donor solvent in a weight ratio between about 0.2-10 of hydrogen donor solvent to hydrocarbon oil, and (2) contacting the liquid admixture with a catalyst composition at a temperature between about 600°-1000° F. for a period between about 0.1-3 hours, wherein the said catalyst composition comprises a naturally occurring porous metal ore selected from the group consisting of manganese nodules, bog iron, bog manganese, nickel laterites and bauxite.
Claim 4
Dependent Claim
98 words
A catalytic process for reducing the metal, sulfur, nitrogen and Conradson Carbon Residue content of a heavy hydrocarbon feedstock which comprises (1) admixing a heavy hydrocarbon oil with a hydrogen donor solvent in a weight ratio between about 0.2-10 of hydrogen donor solvent to hydrocarbon oil, and (2) contacting the liquid admixture with a catalyst composition at a temperature between about 600°-1000° F. for a period between about 0.1-3 hours, wherein the said catalyst composition comprises a naturally occurring porous metal ore selected from the group consisting of manganese nodules, bog iron, bog manganese, nickel laterites and bauxite.
