| titleOfInvention | Olefin epoxidation catalyst as well as preparation method and application thereof |
| abstract | The invention discloses an olefin epoxidation catalyst as well as a preparation method and an application thereof. The catalysts comprises 0.01wt%-0.1wt% of gold, 0.01wt%-0.1wt% of rhodium and 99.8wt%-99.98wt% of a supporter on the basis of the total weight of the catalyst, wherein the supporter is a Ti-SBA-15 molecular sieve modified by gallium, boron and alkali metal together. The catalyst is used for catalyzing propylene epoxidation with TBHP (tert-butyl hydroperoxide) used as an oxidizing agent for generation of epoxy propane, and the catalyst has the good stability. The effective selectivity of the epoxy propane ranges from 90% to 92%, and the conversion rate of propylene is up to 3.5%. |
