Method of removing organometallic compounds from liquid hydrocarbons

Abstract

Abstract Organometallic compounds are separated from liquid hydrocarbons containing the same by contacting the liquid hydrocarbon with an activated charcoal having hydrous ferric chloride impregnated thereon. The contacting may be accomplished at any combination of temperature and pressure at which the hydrocarbon will remain liquid and at which all components used in the process will remain stable. The contacting may be accomplished in essentially any suitable fashion; however, contacting in a fixed bed of the activated charcoal is, generally, most convenient and effective. Impregnation of the activated charcoal is accomplished by contacting a suitable activated charcoal with an aqueous solution of hydrous ferric chloride and thereafter at least partially drying the resulting mixture such that the water remaining is internally adsorbed in the activated charcoal pores. Generally, the presence of water in the impregnated activated carbon adsorbent will improve separation performance. This method of separation is particularly suited to the separation of organo lead compounds from gasoline.
