Process for manufacturing a silica porous material |
摘要 |
A process for manufacturing a silica porous material with high solid acidity, catalytic activity and adsorption ability as well as excellent crystallinity and heat resistance has the steps of adding a compound of metallic element such as Al to a waterglass, aging the resultant mixture, calcining the aged mixture to form a layered crystal, incorporating an organic substance between layers of the layered crystal, calcining the resultant layered crystal for crosslinking the layered crystal. By this process, a plurality of layers formed of SiO4 tetrahedral and metallic oxide constitute a silica porous material, and the gap between adjacent layers of the layered crystal is reduced at a crosslinking site, while the gap of the other portion is expanded to form a micro pore.
