Supported catalyst for direct dehydrogenation of n-butane and preparing method of butenes from n-butane using the same

摘要

The present invention is by direct dehydrogenation of n with a specific supported catalyst - prepared from a butane -butene relates to a method of . By being supported catalyst of the present invention is an alumina carrier of platinum, palladium , or platinum and palladium in the primary catalyst and a copper co-catalyst is supported thereon , the n- to be used in the reaction for producing a butene directly to dehydrogenate butane cracking and by-product produced by the isomerization reaction , carbon deposition , and effectively suppress the deactivation of the catalyst , n - has the effect of significantly improving the conversion rate and selectivity to butane -butene ;
