Abstract

Abstract Hydrorefining of petroleum stocks containing asphaltenes, sulfur and nitrogen with an extruded refractory inorganic oxide catalyst support wherein said support is prepared by admixing a peptizing agent, a surfactant, and a water-insoluble particulate organic polymer having a particle size of from about 1 to about 200 microns with a powdered refractory inorganic oxide and extruding the resulting mixture.

Claims Analysis

Total Claims: 10
Claim 1
Independent Claim 145 words
A process for hydrorefining an asphaltenic hydrocarbonaceous charge stock containing at least one contaminant from the group of sulfurous compounds, and nitrogenous compounds, which process comprises reacting said charge stock with hydrogen at hydrorefining conditions including a pressure above about 1000 psig. and a temperature selected to convert sulfurous and nitrogenous compounds into hydrogen sulfide, ammonia and hydrocarbons, and at least a portion of said charge stock into lower-boiling liquid hydrocarbons, and in contact with a catalyst having a carrier material prepared by a method which comprises: (a) admixing a peptizing agent, a surfactant and a water-insoluble, particulate organic polymer with a powdered refractory inorganic oxide, said organic polymer being characterized by a particle size of from about 1 to about 200 microns; (b) extruding the resulting mixture; and, (c) drying and calcining the extrudate product at a temperature effective to decompose said organic polymer.
Claim 2
Dependent Claim 145 words
A process for hydrorefining an asphaltenic hydrocarbonaceous charge stock containing at least one contaminant from the group of sulfurous compounds, and nitrogenous compounds, which process comprises reacting said charge stock with hydrogen at hydrorefining conditions including a pressure above about 1000 psig. and a temperature selected to convert sulfurous and nitrogenous compounds into hydrogen sulfide, ammonia and hydrocarbons, and at least a portion of said charge stock into lower-boiling liquid hydrocarbons, and in contact with a catalyst having a carrier material prepared by a method which comprises: (a) admixing a peptizing agent, a surfactant and a water-insoluble, particulate organic polymer with a powdered refractory inorganic oxide, said organic polymer being characterized by a particle size of from about 1 to about 200 microns; (b) extruding the resulting mixture; and, (c) drying and calcining the extrudate product at a temperature effective to decompose said organic polymer.
Claim 3
Dependent Claim 40 words
The process of claim 1 further characterized with respect to step (a) in that said surfactant is employed in an amount equivalent to at least about 0.1 wt. % based on the weight of the refractory inorganic oxide employed therein.
Claim 4
Dependent Claim 42 words
The process of claim 1 further characterized with respect to step (a) in that said surfactant is employed in an amount equivalent to from about 0.1 to about 10 wt. % based on the weight of the refractory inorganic oxide employed therein.
Claim 5
Dependent Claim 43 words
The process of claim 1 further characterized with respect to step (a) in that said organic polymer is employed in an amount equivalent to from about 0.5 to about 5 wt. % based on the weight of the refractory inorganic oxide employed therein.
Claim 6
Dependent Claim 21 words
The process of claim 1 further characterized with respect to step (a) in that said refractory inorganic oxide is an alumina.
Claim 7
Dependent Claim 22 words
The process of claim 1 further characterized with respect to step (a) in that said surfactant is a linear primary alcohol polyether.
Claim 8
Dependent Claim 31 words
The process of claim 1 further characterized with respect to step (a) in that said organic polymer is a cellulose with a molecular weight of from about 30,000 to about 50,000.
Claim 9
Dependent Claim 22 words
The process of claim 1 further characterized with respect to step (a) in that said organic polymer is a substantially pure cellulose.
Claim 10
Dependent Claim 32 words
The process of claim 1 further characterized with respect to step (c) in that said extrudate product is dried and calcined at a temperature of from about 325° to about 850° C.
