Abstract: A process for producing a crystalline microporous body under mild conditions using simple equipment in a highly safe state, which process is suited for producing various crystalline microporous bodies usable as adsorbents, catalysts and separating materials. The process is characterized by the use of a crystallization regulator comprising a cationic compound or an amine and the starting material containing a silicate having an ideal compositional formula of NaHSi2O5 or silicon dioxide or the use of the starting material containing silicon dioxide and an aluminum salt, and comprises the step of mixing the reactants, the step of conducting solid-liquid separation of the fine particles thus formed, and the step of crystallizing the solid component thus separted. As compared with the conventional hydrothermal synthesis process requiring such severe conditions as high temperature, pressure and alkalinity, this process is improved in safety and economy, serves to control the pore diameters arbitrarily, and gives a molded body retaining a high content of the porous structure.

Abstract: A method of manufacturing crystalline microporous material suitable for manufacturing a variety of crystalline microporous material under mild reaction conditions and under safe working environmental conditions by using simple installation. The crystalline microporous materials obtained by the present invention may be used as adsorbent agent, catalyst or separating material. According to the characterizing features of the manufacturing method of the present invention, there are provided a method of using cation compound or amine as crystallizing modifier and using, in combination, raw material including canemite or silicon dioxide and a further method using raw material including silicon dioxide and aluminum salt. The method includes a step of mixing these components, a solid-liquid separating step for separating produced fine particles, and a crystallizing step for crystallizing the separated solid component. The invention achieves improvement in safety, economy and so on, in comparison with the coventionally practiced hydrothermal synthesis method which requires severe reaction conditions of high-temperature, high-pressure and strong alkaline. Further, the method allows freedom in adjustment of the pore diameter and allows a higher proportion of porous structure to be maitained in a product when the material is formed into a molded product.

Abstract: A process for the production of alumina includes a method for controlling the specific surface area of alumina. Control of specific surface area is performed by controlling the porous structure of alumina. In the process, an aluminium alkoxide is subjected to hydrolysis for forming an alumina gel. Before hydrolysis a polyether is used as an organic solvent in order to control the porous structure of produced alumina.
