Abstract

A novel composition comprising zinc oxide, zinc phosphate and, optionally, alumina is described which can effectively be used to remove sulfur compounds from a fluid stream by contacting said fluid stream under suitable absorption conditions with the novel composition. A novel method of producing an absorption composition is described where the steps include the formation of a composition comprising zinc oxide, zinc phosphate and, optionally, alumina.
