中文摘要：

根据盐在载体上自发单层分散的理论,通过样品的XRD检测分析,研究了不同担载方法、担载量和焙烧温度对氯化钙在10X分子筛上单层分散的影响.在担载量同为0.6 g/g时,乙醇溶液浸渍样品在500℃下焙烧,氯化钙即能达到完全单层分散;水溶液浸渍样品须在550℃的焙烧温度下氯化钙才能达到完全单层分散,并且出现了明显的离子交换.干混法样品的氯化钙单层分散量显著低于乙醇溶液浸渍法和水溶液浸渍法,在600℃下其氯化钙担载量既使从0.6 g/g降低至0.4 g/g,仍然有显著的氯化钙晶相峰存在.当焙烧温度各自升到一定程度时,三种担载方法制得的样品都出现了新的衍射峰,说明出现了体相反应.乙醇溶液浸渍方法更适合氯化钙在10X分子筛上的热分散;水溶液浸渍方法次之;干混法不适合用于氯化钙在10X分子筛上的热分散.

英文摘要：

According to the theory of spontaneous monolayer dispersion of salt onto carrier, the effects of different load methods, load capacities and calcination temperatures on the monolayer dispersion of Catl2 onto 10X zeolite were studied by using XRD. The CaCl2（0.6 g CaCl2/g 10X） will be dispersed completely when the sample impregnated in ethanol solution is calcined at 500 ℃ or the sample impregnated in aqueous solution is calcined at 550 ℃, and but obvious ion exchange appears for the latter. The monolayer dispersion capacity of samples by dry mixture is remarkably smaller than the one of samples impregnated in ethanol solution and aqueous solution, and the peaks of crystal CaCl2 still exist when the load capacities of CaCl2 are reduced from 0.6 g/g to 0.4 g/g and the samples are calcined at 600 ℃. The solid reaction appears for all samples prepared by three different methods when the calcination temperature rise up to certain extent respectively. The method of impregnation in ethanol solution is suitable, the method of impregnation in aqueous solution is not as good as the method of impregnation in ethanol solution and the method of dry mixture is unsuitable for thermal dispersion of CaCl2 onto 10X zeolite.
