Abstract: A series of honeycomb ceramics matrix structuring catalysts are prepared by different auxiliary ratios and preparation processes,through using cordierite honeycomb ceramics supporter as substrate,pseudo-boehmite as transition coating and Pt-Pd binary noble metal as active ingredients.The as-made catalysts are characterized via XRD and SEM.The loading method for active ingredients,the loading amount of noble metals,the mass and loading amount of auxiliaries and the calcinations conditions for the catalysts are determined by their activity evaluation results in the catalytic oxidation using toluene as model compound.The catalytic oxidation activity of the catalyst is investigated through treating with the tail gas from Fischer-Tropsch synthesis decarbonizing tower under lean oxygen conditions.It is found that the conversion rate of hydrocarbon in the tail gas can exceed 95% over the as-prepared catalyst in the lean oxygen atmosphere.
