摘要: 沸石分子筛广泛应用于石油化工以及精细化学品生产的过程中,它们一般都是通过水热合成路线制备的,该路线使用了大量的水作为溶剂,有时还需加入有机模板剂,从而导致了大量的废水与废气的排放.为了解决这些问题,我们发展了沸石的绿色合成路线,包括无有机模板的沸石晶种导向合成、无溶剂沸石合成、低成本有机模板合成、无锗合成等,这为将来沸石分子筛的可持续工业生产提供了可能,其中无有机模板合成富铝的Beta沸石已经成功地在BASF公司工业化生产.

Abstract: Zeolites as highly efficient catalysts have been widely applied in conversion of oils and production of chemicals, which are normally prepared from hydrothermal routes. Because a large amount of water solvent is employed for the hydrothermal synthesis of zeolites in the presence of organic templates, it is usually formed a large amount of wastes such as polluted water and gases. To solve these issues, we have developed green routes for synthesis of zeolites, including zeolite organotemplate-free synthesis, solvent-free synthesis, use of low-cost templates, and Ge-free synthesis. These approaches offer a good opportunity for sustainable production of zeolites at an industrial scale. Among them, organotemplate-free synthesis of Al-rich Beta zeolite has been commercialized in BASF.
