A 2 mm square lattice channel monolith with a 0.98 mm wall thickness and an overall diameter of 20 mm has been prepared from 5A zeolite powder and Na-bentonite (as a binder) by the unit operations of paste preparation, extrusion, drying and firing. The manufactured monolith, which shows good strength, retains the crystal structure and micropore size of the source 5A zeolite powder, and adsorption measurements made by the constant volume method confirm that the monolith exhibits an equilibrium performance equal to that of commercial 5A zeolite pellets. In addition, the monolith possesses a higher macroporosity than the commercial pellets, a feature which is expected to be of benefit in pressure swing adsorption air separation processes.
