Catalytic hydrodenitrogenation of organic compounds

Claim 2

A process for the catalytic hydrodenitrogenation of an organic nitrogen compound comprising the step of contacting said organic nitrogen compound under suitable hydrodenitrogenation conditions with a catalyst composition consisting essentially of platinum, titanium and a of high purity gamma alumina support.

Claim 3

A process in accordance with claim 1 wherein said organic nitrogen compound is selected from the group consisting of amines, diamines, pyridines, quinolines, porphyrins and benzoquinolines.

Claim 4

A process in accordance with claim 1 wherein the total concentration of platinum in said catalyst composition is in the range of about 0.1 to about 10 weight percent based on the weight of said catalyst composition and wherein the concentration of titanium in said catalyst composition, expressed as titanium dioxide, is in the range of about 0.1 weight percent to about 30 weight percent based on the weight of said catalyst composition.

Claim 5

A process in accordance with claim 1 wherein the concentration of platinum in said catalyst composition is in the range of about 0.5 to about 4 weight percent based on the weight of said catalyst composition and wherein the concentration of titanium in said catalyst composition is in the range of about 2 to about 20 weight percent based on the weight of said catalyst composition.

Claim 6

A process in accordance with claim 1 wherein said organic nitrogen compound is contained in a fluid feed stream.

Claim 7

A process in accordance with claim 5 wherein said suitable hydrodenitrogenation conditions comprise a temperature in the range of about 205° C. to about 538° C., a total system pressure in the range of about 200 psig to about 3000 psig, a hydrogen flow rate in the range of about 100 to about 10,000 SCF/bbl and a residence time for said fluid stream in the presence of said catalyst composition in the range of about 0.1 to about 20 liquid volumes of said fluid feed stream per volume of said catalyst composition per hour.

Claim 8

A process in accordance with claim 5 wherein said suitable hydrodenitrogenation conditions comprise a temperature in the range of about 315° C. to about 427° C., a total system pressure in the range from about 500 psig to about 2000 psig, a hydrogen flow rate in the range of about 500 to about 3000 SCF/bbl. and a residence time for said fluid feed stream in the presence of said catalyst composition in the range from about 0.5 to about 5 liquid volumes of said fluid feed stream per volume of said catalyst composition per hour.
