Application of kaolin in the synthesis of Y zeolite and dimethyl ether

Abstract

高岭土是一种以高岭石和埃洛石为主要成分的粘土类集合体矿物原料,应用范围涉及工业部门的许多领域,在催化中也有着广泛的应用。通过TEM、SEM、XRD和IR等表征手段,分析结果表明,龙岩高岭土产品主要成分为高岭石,埃洛石次之,不同种类的产品还有不同量的水云母、石英等。 高岭土在催化中最重要也是最普遍的应用是作为FCC(FluidCatalyticCracking)催化剂的原料。原位晶化合成的分子筛裂化催化剂因其优异的催化性能广泛应用于石油炼制领域。本文以龙岩高岭土为原料,采用原位晶化法合成用于FCC催化剂的Y型分子筛。通过高岭土原料的选择、高岭土微粒前处理温度的控制、初始投料比例和晶化时间的调节...Kaolin is a kind of mineral clay mainly composed of kaolinite and halloysite. Its application involves a lot of industrial areas. Catalysis industry is one of them. By use of TEM、SEM、XRD and IR, we found that the main component in Longyan Kaolin was kaolinite; halloysite took the second place. There were still some quartaz and hydromica in Longyan kaolin. One of the most important applications...学位:理学硕士院系专业:化学化工学院化学系_物理化学(含化学物理)学号:20012507
