POST-TREATMENT OF DEBORONATED ZEOLITE BETA |
摘要 |
<p>A process for the post-treatment of a zeolitic material having a BEA framework structure, the process comprising (i) providing a zeolitic material having a BEA framework structure, wherein the framework structure of the zeolitic material comprises X2O3 and YO2, wherein Y is a tetravalent element and X is a trivalent element and wherein the molar ratio X2O3: YO2 is greater than 0.02 : 1; (ii) treating the zeolitic material provided in (i) with a liquid solvent system thereby obtaining a zeolitic material having a molar ratio X2O3 : YO2 of at most 0.02 : 1, and at least partially separating the zeolitic material from the liquid solvent system; (iii) treating the zeolitic material obtained from (ii) with a liquid aqueous system having a pH in the range of 5.5 to 8 and a temperature of at least 75 °C.</p> |
