工业上广泛使用作为吸附剂、催化剂的颗粒状分子筛,是由沸石分子筛的微细晶体添加一定量的粘结剂制得的。此法生产分子筛工艺繁杂,而且某些性能和强度不能满足工业应用的要求。为此,我们进行了“一步合成颗粒状A型分子筛”的研究工作。分子筛吸附性能和机械性能的改进工作,国内外已进行了多年研究,主要有改进粘结剂、添加改性剂和补强剂、改变制造分子筛的生产工艺和增加对产品的后处理工序等方法。西德曾研究过在四氯乙烯和邻二氯苯混合介质中,进行分子筛成型的工艺,获得了 Widely used in industry as a sorbent, the catalyst of the granular zeolite, zeolite zeolite from the fine crystals added a certain amount of binder obtained. This method produces complex molecular sieve process, and some properties and strength can not meet the requirements of industrial applications. To this end, we conducted a “one-step synthesis of granular A-type molecular sieve,” the research work. Molecular sieve adsorption and mechanical properties of the improvement work, both at home and abroad have been studied for many years, mainly to improve the binder, add modifier and reinforcing agent, change the manufacturing process of molecular sieve and increase the post-processing procedures and other methods . West Germany has studied in the tetrachlorethylene and o-dichlorobenzene mixed medium, molecular sieve molding process, obtained
