Dehydrogenation with a catalytic composite containing platinum rhenium,a group vi transition metal and an alkali or alkaline earth metal
Abstract
Abstract DEHYDROGENATABLE HYDROCARBONS ARE DEHYDROGENATED BY CONTACTING THEM AT DEHYDROGENATION CONDITIONS WITH A CATALYTIC COMPOSITE COMPRISING A COMBINATION OF CATALYTICALLY EFFECTIVE AMOUNTS OF A PLATINUM GROUP COMPONENT, A RHENIUM COMPONENT, A GROUP VI TRANSITION METAL COMPONENT AND AN ALKALI OR ALKALINE EARTH METAL COMPONENT WITH A POROUS CARRIER MATERIAL. A SPECIFIC EXAMPLE OF THE CATALYTIC COMPOSITE DISCLOSED HEREIN IS A COMBINATION OF PLA;TINUM, RHENIUM, TUNGSTEN AND ALKALI OR ALKALINE EARTH METAL WITH A GAMMA-ALUMINA CARRIER MATERIALIN AMOUNTS SUFFICIENT TO RESULT IN THE COMPOSITE CONTAINING, ON AN ELEMENTAL BASIS, ABOUT 0.05 TO 1 WT. PERCENT PLATINUM, ABOUT 0.05 TO 1 WT. PERCENT RHENIUM, ABOUT 0.01 TO 1 WT. PERCENT TUNGSTEN AND ABOUT 0.1 TO 5 WT. PERCENT OF THE ALKALI OR ALKALINE EARTH METAL.
