| titleOfInvention | Catalyst for selective oxidation of hydrogen sulfide and preparation method thereof |
| abstract | The invention belongs to the technical field of sulfur recovery, and particularly relates to a hydrogen sulfide selective oxidation catalyst and a preparation method thereof. The carrier raw materials comprise metatitanic acid, silicon dioxide powder and calcium silicate, and iron oxide and calcium oxide are used as active components; the specific surface area of the silicon dioxide powder is 40-60m 2 A fumed silica powder per gram. The carrier ensures that the catalyst has a proper pore structure, avoids the Claus reverse reaction of the catalyst in a selective oxidation section, and reduces the sensitivity of the catalyst to the content of water vapor and oxygen; the catalyst of the invention has high activity, is not sensitive to the influence of the steam and oxygen in the process gas, has high side pressure strength, and has H 2 High S conversion rate. The catalyst has hydrogen sulfide conversion rate up to 95%, sulfur yield up to 90% and side pressure strength up to 120N/cm, and thus has high sulfur recovering rate and obvious economic and social benefits. |
