| titleOfInvention | A kind of preparation method of shell type Al-MCM-48 catalyst |
| abstract | The invention relates to a preparation method of a shell-type Al-MCM-48 catalyst, which specifically comprises the following steps: preparing a sodium hydroxide solution, transferring it to a water bath at 35° C., and slowly adding the sodium hydroxide solution to the sodium hydroxide solution after 5-10 min. Add aluminum sulfate octadecyl hydrate and hexadecyl trimethyl ammonium bromide, dissolve them respectively, after dropping to room temperature, slowly add ethyl orthosilicate dropwise and stir, the molar ratio of the above-mentioned reactant raw materials is 1.0TEOS:0.65 CTAB: 0.5NaOH: 62H 2 O: 0.01Al 2 (SO 4 ) 3 • 18H 2 O, the obtained mixture gel; the mixed gel was put into a stainless steel reactor and crystallized; the crystallization product was filtered by low pressure suction, Wash and dry to obtain Al-MCM-48 original powder; the original powder is calcined at constant temperature to obtain a shell-type Al-MCM-48 catalyst. The catalyst prepared by the invention has larger specific surface area and pore size, and the acidity is enhanced. |
