Abstract
The invention relates to a process for dehydrogenation of a hydrocarbon feedstock in the presence of a catalyst that comprises a noble metal M that is selected from the group that consists of platinum, palladium, rhodium, and iridium, at least one promoter X1 that is selected from the group that consists of tin, germanium, and lead, and optionally a promoter X2 that is selected from the group that consists of gallium, indium and thallium, an alkaline or alkaline-earth compound and a porous substrate, in which the atomic ratio X1/M and optionally X2/M is between 0.3 and 8, the H/M ratio that is measured by hydrogen adsorption is greater than 0.40, and the bimetallicity index BMI that is measured by hydrogen/oxygen titration is greater than 108.
