Engineering Research Equipment Grant/UHV Thermogravimetric Analyzer

这笔赠款是提供资金购买卡恩TG 121 扩散研究中使用的热重系统， 柱撑粘土中有机大分子的吸附。 柱撑粘土 是由非常规则的多孔结构组成的催化材料 用于例如瓦斯油裂化、甲醇转化为 烯烃和甲苯乙基化。 该设备将用于研究各种有机物的扩散率 分子在柱撑粘土中的低压吸附实验， Perkin-Elmer TGS-2超高真空热重系统。 该程序将 包括将少量细磨的柱撑粘土置于 石英微量天平，将气体引入装置中，然后 测量摄取量。 没有其他热重系统， 南加州大学化学工程系，这将是伟大的 有利于PI在制备新的Pillard材料方面的研究工作 并用于改善柱撑的催化和筛分性能， 粘土已经存在。 他已经让 在这一领域的贡献，这一设备将大大有利于他的 实验的努力。

This grant is to provide funds for the purchase of a Cahn TG 121 thermogravimetric system to be utilized in studies of diffusion and sorption of large organic molecules in pillared clays. Pillared clays are catalytic materials consisting of very regular porous structures with uses in for example, gas oil cracking, methanol conversion to olefins and toluene ethylation. The equipment will be used to study the diffusivity of various organic molecules in pillared clays by low pressure sorption experiments in a Perkin-Elmer TGS-2 UHV thermogravimetric system. The procedure will consist of placing small amounts of finely ground pillared clay in the quartz microbalance, introducing gas into the apparatus and then measuring the uptake. There are no other thermogravimetric systems in the Chemical Engineering Department at USC and this will be of great benefit to the PI's research effort in preparing new pillard materials and for improving the catalytic and sieving properties of pillared clays already in existence. He has already made valuable contributions in this area and this equipment will greatly benefit his experimental efforts.
