ABSTRACT
Zeolitic materials are used as sorbents and catalysts in a variety of processes within the chemical, petroleum, petrochemical, and food industries. Zeolite crystals are incorporated into binders (such as amorphous aluminosilicate) and perhaps a diluent (typically a clay mineral), and used in the form of powder (in fluidized beds) or pellets (in fixed beds). Alternatively, zeolite crystals are coated onto a porous membrane support and used in (catalytic) membrane permeation devices.
