Abstract
A crystalline inorganic porous material having two different types of pores which are macropores having a diameter in the micrometer range and micropores having a diameter in the 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.
