    摘要: A porous material composed of many SiO.sub.4 tetrahedra sheets having interlayer bridges of SiO.sub.2. It has pores having a diameter of 10 .ANG. or above, and possesses the properties of a solid acid formed by the isomorphous substitution of metal atoms for Si of SiO.sub.4 frameworks. It is made by a process including introducing an organic substance into interlayer space of crystals of layered silicates to expand the spacing between crystal layers, as well as forming bridges of SiO.sub.2 therebetween, bringing the intercalated compounds into contact with a metal salt to link metal atoms to the SiO.sub.4 frameworks, and firing the products. The material can withstand a temperature of 800.degree. C., has a pore diameter larger than that of zeolites, etc., and is useful in making an adsorbent or catalyst for molecules having a high molecular weight, such as a catalyst for the catalytic cracking of petroleum.

    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 SiO.sub.4 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.
