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.
