Title:
HYDROGENATED TIO2 DENITRATION CATALYST, PREPARATION METHOD THEREFOR AND APPLICATION THEREOF
Document Type and Number:
WIPO Patent Application WO/2021/088277
Kind Code:
A1
Abstract:
The present invention relates to the technical field of flue gas denitration catalysts. Disclosed are a hydrogenated TiO2 denitration catalyst, a preparation method therefor, and application thereof. The hydrogenated TiO2 denitration catalyst has a crystal form of anatase, has oxygen vacancies and surface hydroxyl groups. The hydrogenated TiO2 denitration catalyst contains TiO2, SO3, and P2O5; and based on the total weight of the hydrogenated TiO2 denitration catalyst, the content of TiO2 is 98-99.8% by weight, the content of SO3 is 0.2-1% by weight, and the content of P2O5 is 0.1-0.2% by weight. The hydrogenated TiO2 denitration catalyst has a high denitration activity at 300-400°C and a high selectivity of N2 of over 85%, and is applicable to NH3-SCR denitration.
