| 简介 |
The invention relates to a method for dehydrogenating a hydrocarbonated load in presence of a catalyst containing a noble metal M selected from the group including platinum, palladium, rhodium and iridium, at least one promoter X1 selected in the group comprising tin, germanium, lead, and optionally a promoter X2 selected from the group comprising gallium, indium and thallium, an alkaline or alkaline-earth compound and a porous substrate, wherein the atomic ratio X1/M and optionally the atomic ratio X2/M is in a range of 0.3 to 8, the ratio Hir/M as measured by hydrogen adsorption is higher than 0.40, and the bimetallic index IBM as measured by hydrogen/oxygen titration is higher than 108. |
