交链蒙托土是近年来引人瞩目的新型催化材料,但有关其孔结构和烃类分子的吸附与扩散研究的报导甚少.我们采用低温氮吸附容量法研究了中国黑山蒙托土(钙型原土)及Ni,Al,Zr交链蒙托土(Ni-CLB,Al-CLB,Zr-CLB)的孔结构;以石英弹簧作为吸附量探测器的静态重量吸附装置,测定了正辛烷、正癸烷、1,3,5-三甲苯在这些样品上的扩散速率.获得了了解交链蒙托土的孔特性与催化动力学行为的有意义信息.
The cross-linked montmorillonite is a new type of catalysis material attracting attention in recent years, but few reports on the adsorption and diffusion of its pore structure and hydrocarbon molecules.We used low-temperature nitrogen adsorption capacity method to study the characteristics of Montenegro Calcium original soil) and Ni, Al, Zr intercalated montmorillonite (Ni-CLB, Al-CLB, Zr-CLB) pore structure; Quartz spring as the adsorption capacity detector static weight adsorption device, was measured positive Octane, n-decane, and 1,3,5-trimethylbenzene on these samples obtained interesting information on the pore properties and catalytic kinetic behavior of the cross-linked montmorillonite.
