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.
