Abstract
Abstract A process for denitrogenation of high nitrogen content hydrocarbon feeds comprising contacting the feed with hydrogen under denitrogenation conditions in the presence of a catalyst comprising an active metallic component comprising at least one metal having hydrogenation activity and at least one oxygenated phosphorus component and a support component comprising at least one non-zeolitic, porous refractory inorganic oxide matrix component and at least one crystalline molecular sieve zeolite component.

Claims Analysis
Total Claims: 12
Claim 1
Independent Claim
116 words
A process for denitrogenation of high nitrogen content hydrocarbon feeds comprising contacting the feed with hydrogen under denitrogenation conditions in the presence of a catalyst comprising an active metallic component comprising at least one metal having hydrogenation activity and at least one oxygenated phosphorus component, and a support component consisting essentially of at least one nonzeolitic, porous refractory inorganic oxide matrix component selected from the group consisting of alumina, silica, zirconia, titania, magnesia and combinations thereof and at least one crystalline molecular sieve zeolite component, wherein the high nitrogen content feed is a whole petroleum or synthetic crude oil, coal, shale or biomass liquid, or a fraction thereof containing at least about 0.4 wt % nitrogen.
Claim 2
Dependent Claim
116 words
A process for denitrogenation of high nitrogen content hydrocarbon feeds comprising contacting the feed with hydrogen under denitrogenation conditions in the presence of a catalyst comprising an active metallic component comprising at least one metal having hydrogenation activity and at least one oxygenated phosphorus component, and a support component consisting essentially of at least one nonzeolitic, porous refractory inorganic oxide matrix component selected from the group consisting of alumina, silica, zirconia, titania, magnesia and combinations thereof and at least one crystalline molecular sieve zeolite component, wherein the high nitrogen content feed is a whole petroleum or synthetic crude oil, coal, shale or biomass liquid, or a fraction thereof containing at least about 0.4 wt % nitrogen.
