Abstract
PURPOSE: To recover the activity of a supported platinum group metal catalyst deactivated by being used in steam reforming or hydrogenolysis of hydrocarbons to such a degree that the catalyst can be recycled, by treating the deactivated catalyst with an aq. org. alkali soln. and further treating it with an aq. soln. of hydrazine, HCHO, etc.
