Abstract
Paraffinic hydrocarbons are dehydrogenated in contact with a catalytic composite comprising from about 0.01 to about 2.0 wt. % Group VIII metal and from about 0.01 to about 0.1 wt. % lithium impregnated on an alumina support, said alumina having been hydrothermally treated in steam at a temperature of from about 800.degree. to about 1200.degree. C.
Claims11
A process for dehydrogenating a paraffinic hydrocarbon which comprises contacting said hydrocarbon at dehydrogenation reaction conditions including a temperature of from about 400.degree. to about 700.degree. C. with a catalytic composite of from about 0.01 to about 2.0 wt. % Group VIII metal component and from about 0.01 to about 0.1 wt. % of an alkali metal or alkaline earth metal component with a precalcined alumina support which has been hydrothermally treated with steam at a temperature of from about 800.degree. to about 1200.degree. C. after its calcination and prior to the compositing of said metal components therewith.
