Abstract
A method of extending the useful life of a catalyst employed in the endothermic catalytic reforming of gaseous hydrocarbons in which a substantial portion of the sulfur contained in such gaseous hydrocarbons is removed by contacting them with an aqueous solution of a water soluble metallic salt having a free metallic ion which forms an insoluble precipitate with sulfur. A preferred salt is zinc chromate.
