Zeolite is generally used in the form of beads or pellets in various industrial fields. These types of use, however, have some serious disadvantages such as a pressure loss in the reaction tower or a powdering of the zeolite through beads rubbing against each other. Therefore, in this study, the zeolite sheets were prepared by using a papermaking technique intending the manufacture of the honeycomb structure which improved these defects to a great extent. Typical composites of sheetmaking stuffs were pulp (9%), zeolite (61.5%), kaolin (18%) and glass fiber (11.5%). When 0.5% polydiallyldimethylammonium chloride (cationic retention aid) and 0.5%–1.0% anionic polyacrylamide (anionic retention aid) with high molecular weight (4.0 × 106) on these solids were added, the retention of inorganic compounds was higher than 90%. The drainage time was adequately short. These results suggest that the method can be applied to the industrial production.
