Method for modifying the porosity of aluminosilicates and silicas, and mesoporous compositions obtained thereof.

摘要

Process of modifying the porosity of an aluminosilicate or silica whose porosity is not affected by an acid extraction. The process involves reacting said aluminosilicate or silica aluminate alkaline extraction followed MATERIAL TREATED aluminate extractive agent to form the aluminosilicate or silica Porosity AMENDED. THE PROCESS IS APPLICABLE TO THOSE Zeolites do not react ACIDA extraction conditions, eg Ferrierite, AND it IS APPLICABLE TO THOSE ARE zeolites structurally unstable ACIDA EXTRACTION CONDITIONS AS THE MINERAL BIKITAITO. ONES DESCRIBED MESOPOROUS compositions, including a mesoporous zeolite ferrierite and mesoporous DCM-3.
