| titleOfInvention | Propane dehydrogenation catalyst, preparation method thereof and method for preparing propylene by propane dehydrogenation |
| abstract | The invention relates to the field of catalysts, and discloses a propane dehydrogenation catalyst, a preparation method thereof and a method for preparing propylene by propane dehydrogenation. The propane dehydrogenation catalyst comprises a carrier and a Pt component, a Sn component and a Na component which are loaded on the carrier, wherein the carrier is a three-hole spherical sepiolite mesoporous molecular sieve silica gel composite material, the three-hole spherical sepiolite mesoporous molecular sieve silica gel composite material contains sepiolite, a mesoporous molecular sieve material with a two-dimensional hexagonal pore structure and silica gel, the average particle size of the three-hole spherical sepiolite mesoporous molecular sieve silica gel composite material is 10-60 mu m, and the specific surface area of the three-hole spherical sepiolite mesoporous molecular sieve silica gel composite material is 100-300m 2 The pore volume is 0.7-1.3mL/g, the pore diameter is in trimodal distribution, and the first most probable pore diameter, the second most probable pore diameter and the third most probable pore diameter corresponding to the trimodal distribution are 1-5nm, 5-15nm and 10-40nm respectively. The propane dehydrogenation catalyst shows good catalytic performance when used for preparing propylene by propane dehydrogenation. |
