本研究以碳化硅为载体,Pt为活性组分,通过浸渍法制备了一系列的Pt/SiC催化剂,并考察了焙烧温度、空速、Pt负载量以及助剂对Pt/SiC催化剂的活性的影响。结果表明:
催化剂的催化活性随着Pt的负载量呈现出先升高后降低的趋势,Pt的最佳负载量为3%,其最适宜的焙烧温度为500℃,催化剂具有较宽的空速操作范围。加入过渡金属助剂可以显著提高催化剂的催化活性,其中Fe对催化剂活性提高更为显著。

In this study, SiC as a carrier, Pt reactive component, Prepared by impregnating a series of Pt/SiC catalyst and influence of temperature, space velocity, Pt loading and auxiliaries Pt/SiC catalyst for the activity. The results show : the catalytic activity with Pt loading showing first and then falling trend, Pt the best load of 3%, the most suitable baking temperature of 500 ° C, catalyst space velocity with a wide operating range. To the transition metal additives can significantly enhance the catalytic activity, on the catalytic activity of Fe raise more notable.
