Hydrogenation of organic compounds
Abstract
Abstract NOVEL SULFIDED HYDROGENATION CATALYSTS ARE FORMED BY IMPREGNATING A SUITABLE SUPPORT MATERIAL WITH AN AQUEOUS SOLUTION OF A SALT OF A TRANSITION METAL: HEAT-TREATING THE IMPREGNATED SUPPORT AT A TEMPERATURE ABOVE 500*F. TO FORM CHEMICAL COMPLEXES ON THE SURFACE OF THE SUPPORT AND TO DRIVE OFF MOISTURE AND ABSORBED OXYGEN: CONTACTING THE SUPPORTED METAL COMPLEX WITH HYDROGEN SULFIDE; ACTIVATING THE SURFACE COMPELX BY CONTACTING THE SUPPORTED METAL SULFIDE COMPLEX WITH A SOLUBLE ORGANOMETALLIC COMPOUND WHEREIN THE METAL CONSTITUENT IS SELECTED FROM GROUPS I, II AND III OF THE PERIODIC CHART OF THE ELEMENTS, AND THEREAFTER TREATING THE ACTIVATED SUPPORT MATERIAL IN THE PRESENCE OF A GASEOUS STREAM CONTAINING HYDROGEN AT A TEMPERATURE OF AT LEAST 300*F. TO FORM A HIGHLY STABLE HETEROGENEOUS SULFIDED CATALYST. THE NOVEL SUPPORTED CATALYSTS OF THE INSTANT INVENTION HAVE BEEN FOUND TO HIGHLY ACTIVE FOR THE HYDROGENATION OF ORGANIC FEEDSTOCKS CONTAINING SULFUR UNDER EXTREMELY MILD CONDITIONS.
