摘要： A process for producing an inorganic porous material, comprising the steps of preparing an aqueous medium solution containing water-glass as a silica source, a water-soluble polymer and an acid, causing phase separation and gelation in the solution at the same time to form a wet gel, and washing and drying the gel.According to the present invention, use of water-glass which is easily acquired as a silica source makes it possible to produce porous silica having mutually continuous through holes with macro-pores. According to the present invention, the diameter of each macro-pore can be controlled to a desired value.

摘要： A crystalline inorganic porous material having two different types of pores which are macropores having a diameter of a micrometer range and micropores having a diameter of an angstrom range, at least part of the skeleton thereof having a zeolite structure. The crystalline inorganic porous material of the present invention has macropores and micropores and enables the effective transport of a substance by the macropores, thereby improving the effectiveness of the micropores of zeolite. Since a molded product can be obtained without using a binder, the selectivity of a reaction of interest can be improved in an acidic catalytic reaction or precision separation in adsorption/separation becomes possible.
