Abstract
The present invention relates to the use of a non-aqueous liquid such as phenols, glycols, aromatic hydrocarbons, diesel fuel, kerosene, and mixtures thereof as a moistening agent in a packed bed process, wherein the packed bed contains a composition for removing sulfur compounds from fluid streams, the composition containing a carrier composition, an iron oxide composition, and a non-aqueous liquid moistening agent. The non-aqueous liquid moistening agent is used in place of water and thus avoids the problems associated with using water as a moistening agent.
