Abstract
The application belongs to the field of catalysis technology and discloses a high-density long-chain alkane dehydrogenation catalyst and a preparation method thereof.The high-density long-chain alkane dehydrogenation catalyst is a combination of Pt, Sn, Ni, Fe and alkali metals or oxides supported on a mesoporous and microporous alumina carrier.The catalyst is mainly used in the reaction process of dehydrogenation of long-chain normal alkane (C10-C13) to prepare mono-olefins, the catalyst uses a high-density carrier in the form of a rolling ball, the preparation process is more safe and environmentally friendly, and the catalyst dehydrogenation life is more improved, and the dehydrogenation stability is improved by 15-30%.
