  • Patent number: 5707598
    Abstract: 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.

  • Patent number: 5382558
    Abstract: A heat resistant layered porous silica having a honeycomb porous structure comprises a plurality of waved or bent sheet layers of crystalline layered silicate superposed one after another, and the neighboring sheets are partially bonded by siloxane bonding. The spacing between the neighboring sheet layers is narrowed toward the bonded portions and expanded at other portions to thereby form fine pores. The layered porous silica contains alkali metal ions in an amount of 0.2% by weight or less and has a specific surface area of 1,000 m.sup.2 /g or more.The layered porous silica has a large specific surface area, and exhibits an excellent heat resistance and adsorption of organic substances such as fuel.
