Abstract
Abstract PCT No. PCT/JP91/01226 Sec. 371 Date Sep. 30, 1992 Sec. 102(e) Date Sep. 30, 1992 PCT Filed Sep. 13, 1991 PCT Pub. No. WO92/12104 PCT Pub. Date Jul. 23, 1992.A plastic or moldable composition of zeolite is obtained by adding 0.1-20 parts by weight of a beta -1.3-glucan, 1:1 layer-type clay mineral and 2:1 layer-type clay mineral together with an adequate amount of water to 100 parts by weight of zeolite powder, and then kneading the resultant mixture. The composition may be, for example, extrusion-molded to a honeycomb structure, and calcined, to provide a calcined article of honeycomb structure of zeolite which has a high dimensional accuracy and strength, and hence is useful as a drying agent, a catalyst or a carrier material therefor. The calcined article of zeolite has an excellent mechanical strength.
