Summary: | The invention discloses a synthesis method of nano BaKL zeolite applied to low-carbon alkane aromatization, and relates to the technical field of zeolite preparation. The method mainly comprises the following steps: mixing a barium source, an alkali source, an aluminum source, a silicon source and water according to a molar ratio to prepare sol, and crystallizing under a certain condition to obtain nano-scale BaKL zeolite. According to the invention, the BaKL zeolite with nanoscale, high crystallinity and hierarchical pore structure can be synthesized under the conditions of low silica-alumina ratio feeding and no addition of a template agent or a structure-directing agent. When the BaKL zeolite provided by the invention is used in a low-carbon alkane aromatization reaction, the yield of aromatic hydrocarbons, especially the yield of C8 aromatic hydrocarbons, can be obviously improved. Compared with a traditional method, the disclosed method is simple in preparation process, high in raw material utilization r |
