摘要： A catalyst composition comprising palladium, silver and a support material (preferably alumina) is contacted at a relatively low temperature (of up to about 60.degree. C.) with a liquid composition comprising an effective reducing agent (preferably an alkali metal borohydride, hydrazine, formaldehyde, formic acid, ascorbic acid, dextrose, aluminum powder). Preferably, at least one alkali metal compound (more preferably KOH, RbOH, CsOH, KF) is also present in the liquid composition. An improved process for selectively hydrogenating acetylene (to ethylene) employs this wet-reduced catalyst composition.

摘要： An improved process for removing metals from heavy oils and other hydrocarbon feed streams is disclosed. The process includes adding phosphorus sulfide to the hydrocarbon feed stream under suitable demetallizing conditions. It is believed that phosphorus sulfide reacts with the metals contained in the hydrocarbon containing feed stream to form oil insoluble compounds that can be removed from the hydrocarbon containing feed stream by any conventional method, such as filtration, centrifugation, or decantation.
