MWW TYPE ZEOLITE SUBSTANCE, PRECURSOR SUBSTANCE THEREFOR, AND PROCESS FOR PRODUCING THESE SUBSTANCES |
摘要 |
A process for easily synthesizing a zeolite substance containing an element having a large ionic radius in the framework at a high ratio. This process comprises the following first to fourth steps: First Step: a step of heating a mixture containing a template compound, a compound containing a Group 13 element of the periodic table, a silicon-containing compound and water to obtain a precursor (A); Second Step: a step of acid-treating the precursor ( A) obtained in the first step; Third Step: a step of heating the acid-treated precursor (A) obtained in the second step together with a mixture containing a template compound and water to obtain a precursor (B); andFourth Step: a ste p of calcining the precursor (B) obtained in the third step to obtain a zeolit e substance. |
