| titleOfInvention | Ce-based composite catalyst suitable for hydrogen sulfide catalytic reduction desulfurization and denitrification process and preparation method thereof |
| abstract | The invention discloses a Ce-based composite catalyst suitable for a hydrogen sulfide catalytic reduction desulfurization and denitrification process and a preparation method thereof. The composite catalyst is Al 2 O 3 ‑TiO 2 Is a composite carrier and is loaded with an active component CeO 2 And (3) the product is obtained. Simultaneously, the preparation method of the Ce-based composite catalyst suitable for the hydrogen sulfide catalytic reduction desulfurization and denitrification process is also disclosed, and comprises the following steps: 1) firstly preparing composite carrier Al 2 O 3 ‑TiO 2 (ii) a 2) Post-preparation of composite catalyst CeO 2 /Al 2 O 3 ‑TiO 2 . The catalyst prepared by the method has a relatively simple process, is convenient for industrial large-scale production, can be synchronously removed at the common industrial catalytic temperature range of 200-400 ℃, and generates a byproduct NH 3 The amount of (a) is also smaller. Therefore, the method has higher economic value and popularization value, and can realize higher conversion rate of the nitrogen oxide and the sulfide through modifying the catalyst and reaction conditions in the later period. |
