| titleOfInvention | Catalyst for preparing propylene by propane dehydrogenation and preparation method and application thereof |
| abstract | A catalyst for preparing propylene by propane dehydrogenation and a preparation method and application thereof belong to the field of catalysts for preparing propylene by propane dehydrogenation. The method is characterized in that: the catalyst comprises an active component and a carrier, wherein the active component accounts for the following components in percentage by mass: 0.25-0.45%, Sn: 0.05-0.2%, K: 0.5-1.1%; the carrier is an Al-Si-C-O composite carrier, and the Al-Si-C-O composite carrier is a spherical carrier with the diameter of 1.6-2.0 mm. The preparation method can effectively combine the carriers of aluminum, silicon and carbon to form a unified whole. The support is modified by special methods, on the one hand, to have a higher strength and, on the other hand, to have a larger pore volume. In addition, the catalyst has good heat conductivity and mechanical property, can avoid the occurrence of hot spots in the reaction process, has good abrasion resistance, and greatly prolongs the service life of the catalyst. |
