Dehydrogenation method and multicomponent catalytic composite for usetherein

Abstract

Abstract DEHYDROGENATABLE HYDROCARBONS ARE DEHYDROGENATED BY CONTACTING THEM AT DEHYDROGENATION COIDITIONS WITH A CATALYTIC COMPOSITE, COMPRISING A COMBINATION OF CATALYTICALLY EFFECTIVE AMOUNTS OF A PLATINUM GROUP COMPONENT, A TIN COMPONENT AND A GERMANIUM COMPONENT WITH A POROUS CARRIER MATERIAL. A SPECIFIC EXAMPLE OF THE CATALYTIC COMPOSITE DISCLOSED HEREIN IS A COMBINATION OF A PLATINUM GROUP COMPONENT, A TINCOMPONENT, A GERMANIUM CONPONENT AND AN ALKALI OR ALKALINEEARTH COMPONENT WITH A POROUS CARRIER MATERIAL WHEREIN SUBSTANTIALLY ALL OF THE PLATINUM GROUP COMPONENT IS PRESENT AS THE ELEMENTAL METAL AND SUBSTANTIALLY ALL OF THE GERMANIUM COMPONENT IS PRESENT IN AN OXIDATION STATE ABOVE THE ELEMENTAL METAL, WHEREIN THE COMPOSITE CONTAINS ABOUT 0.01 TO ABOUT 2 WT. PERCENT OF PLATINUM GROUP METAL, ABOUT 0.01 TO ABOUT 5 WT. PERSENT TIN, ABOUT 0.01 TO ABOUT 5 WT. PERCENT GERMANIUM AND ABOUT 0.01 TO ABOUT 5 WT. PERCENT ALKALY OR ALKALINE EARTH METAL.
