Abstract Catalytic cracking of C12-C32 hydrocarbons as model compounds was performed using hierarchical zeolite-containing mesoporous silica and silica-alumina. Curie point pyrolyzer (CPP) was used as a new evaluation method of catalytic cracking. The activity and product selectivity using hierarchical catalysts were compared with those of zeolite-kaolin mixed catalyst. The conversion and gasoline yield were improved with increasing the number of carbon in raw materials, and alkene showed higher reactivity than alkane compared with the same carbon number. It was thought that the hierarchical catalysts, which had the larger amounts of mesopores, would show the higher gasoline yield and conversion than kaolin mixed catalysts. Regardless of the type of zeolite, the gasoline yield increased linearly with increasing the conversion. In contrast to this, Y-zeolite-containing catalysts exhibited the higher ratios of branched hydrocarbons probably because of the presence of its larger micropores.

使用居里点热解仪通过含β-和Y-沸石的分级介孔二氧化硅和二氧化硅-氧化铝催化裂化C12-C32烃

摘要 使用含沸石的分级介孔二氧化硅和二氧化硅-氧化铝对作为模型化合物的 C12-C32 烃进行催化裂化。居里点热解器（CPP）作为一种新的催化裂化评价方法。将分级催化剂的活性和产物选择性与沸石-高岭土混合催化剂的活性和产物选择性进行了比较。随着原料中碳数的增加，转化率和汽油收率得到提高，与相同碳数相比，烯烃表现出比烷烃更高的反应活性。据认为，具有较大量中孔的分级催化剂将显示出比高岭土混合催化剂更高的汽油产率和转化率。不管沸石的类型如何，汽油收率随着转化率的增加而线性增加。与此相反，
