摘要 以堇青石蜂窝陶瓷载体为基体,拟薄水铝石为过渡涂层,Pt-Pd双元贵金属为活性组分,采用不同助剂配比及制备工艺得到系列蜂窝陶瓷基结构化催化剂。通过催化剂的XRD和SEM结构表征,以及甲苯为模型化合物的催化氧化活性评价结果,确定了活性组分负载方法、贵金属负载量、助剂质量比及负载量和煅烧条件。最终以贫氧条件下的费-托合成脱碳塔尾气为研究对象,考察了催化剂的催化氧化活性,结果表明,制得的催化剂在贫氧条件下对脱碳塔尾气中的烃类转化率大于95%,达到环保排放要求。

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.
Key words:  cordierite honeycomb ceramics    Pt-Pd    tail gas from decarbonizing tower    lean oxygen
