AN ALKALI-MODIFIED CATALYST FOR DEHYDROGENATION AND DEHYDROISOMERIZATION OF N-BUTANE AND A METHOD FOR PRODUCING A MIXTURE OF N-BUTENE, 1,3-BUTADIENE AND ISO-BUTENE WITH CONTROLLED RATIO OF ISOBUTENE TO N-BUTENE USING THE SAME

摘要

The present invention relates to a catalyst for dehydrogenation and dehydroisomerization of n-butane modified by alkali metal addition and a method for manufacturing a mixture of n-butene, 1,3-butadiene and isobutene in which a production ratio of isobutene to n-butene is controlled in the dehydrogenation and dehydroisomerization of n-butane using the same and, more specifically, to a catalyst modified by adding alkali metal in which an addition ratio as compared with platinum is controlled to a chloridized catalyst in which alumina carriers are impregnated with platinum and tin, and to a method for manufacturing a high-yield mixture of n-butene, 1,3-butadiene and isobutene in which a production ratio of isobutene to n-butene is controlled in the dehydrogenation and dehydroisomerization of n-butane using the same.
