Cesium promoted Co3O4 catalyst deposited on ceramic foam support for nitrous oxide decomposition

Popis výsledku v původním jazyce

The preparation of Co3O4 De-N2O catalyst on ceramic foam structured support by organic-assisted impregnation is investigated. Acetic acid, citric acid, glycerol, glycine and urea are tested as organic impregnation agents. The catalysts are characterized by AAS, BET, SEM, TPR-H2 and XRD. Using glycerol as the organic impregnation agent leads to the highest improvement of the catalyst De-N2O activity. Preparation of the catalyst by glycerol-assisted impregnation is further optimized. The optimal glycerol-to-cobalt molar ratio of the impregnation solution is found to be 1:1. The optimized glycerol-assisted impregnation method is used for preparation of Cs-doped Co3O4 catalysts on ceramic foams. Based on De-N2O catalytic tests in simulated nitric acid plant tail-gas (N2O, O2, H2O, NO, N2) the optimal Cs loading is found to be between 1.5 and 1.9 wt. % of CO3O4.
