| titleOfInvention | Spherical double-mesoporous attapulgite composite carrier and preparation method and application thereof |
| abstract | The invention relates to the field of catalysts, and discloses a spherical double-mesoporous attapulgite composite carrier, and a preparation method and application thereof. The method for preparing the spherical double-mesoporous attapulgite composite carrier comprises the following steps: (1) in the presence of a template agent, contacting a silicon source with an ammonia water solution to obtain a mesoporous material; (2) contacting water glass with an inorganic acid solution to obtain silica gel; (3) mixing the mesoporous material, the silica gel and the attapulgite, and then sequentially carrying out filtration washing, ball milling, pulping and spray drying on the mixed material, wherein the filtration washing in the step (3) is carried out in a ceramic membrane filter, and the content of sodium ions in the mixed material after filtration washing is not higher than 0.2 wt% and the content of a template agent is not higher than 1 wt% in terms of sodium element. According to the method, the ceramic membrane filter is subjected to cross-flow filtration, so that the separation is efficient and simple, the template agent is removed without calcination in the later stage, and the method is energy-saving and environment-friendly. |
