Abstract
A process for selectively reducing nitrile contaminants in fluids such as water, methanol or hydrocarbon streams containing mono olefins and which contain minor amounts of contaminants comprising nitriles in the presence of hydrogen and a supported cobalt catalyst. In the olefin stream the nitrile contaminants are substantially reduced without substantial reduction of the mono olefins.
Claims16
A process for the treatment of olefin containing hydrocarbon streams comprises feeding a hydrocarbon stream consisting essentially of a light naphtha cut containing mono olefins and minor amounts of contaminants comprising nitriles, in the presence of hydrogen and a cobalt catalyst at a temperature in the range of 30.degree. to 200 .degree. C. and a pressure in the range of 50 to 300 psig to reduce the contaminants without substantial reduction of the mono olefins.
