There is provided macrostructures of porous inorganic material which can have
controlled size, shape, and/or porosity and a process for preparing the macrostructures.
The macrostructures comprise a three-dimension network of particles of porous inorganic
materials. The process for preparing the macrostructures involves forming an admixture
containing a porous organic ion exchanger and a synthesis mixture capable of forming
a porous inorganic material and then converting the synthesis mixture to a solid
porous inorganic material. After formation of the composite material, the porous
organic ion exchanger can be removed from the composite material to obtain the
macrostructures, either before or after the porous inorganic material is hydrothermally
treated with a structure directing agent to convert at least a portion of such
porous inorganic material to a crystalline molecular sieve composition. The resulting
macrostructure is composed of particles of the crystalline molecular sieve composition.
