PURPOSE: To obtain a catalyst carrying inorg. porous body freed from impurities to maintain catalysis by drying a swelling layer compd. into which an inorg. pillar material is inserted between the layers of the swollen compd.
CONSTITUTION: A swelling layer compd. as the main material is mixed with a solvent such as water or further kneaded, as required, to incorporate the solvent between layers. An inorg. pillar is mixed with the compd. and inserted between the layers. The mixed soln. thus obtained is subjected to solid-liq. separation such as centrifugation, and a catalyst is deposited on the obtained precipitate and then dried. Consequently, impurities are not infiltrated in synthesis, and the catalyst is effectively used. The cleaning stage to remove impurities is also minimized.
