A method for the preparation of an adsorbent honeycomb body is formed from active silica gel, can be used in an atmosphere with 100 relative humidity.

摘要

PURPOSE:To obtain an adsorbent having high adsorption efficiency and small permeation resistance by dipping a honeycomb layered body of specified properties in a water glass soln., and then dipping in acid so that active silica gel of specified pore diameter is coupled with the inorg. fiber paper in the layered body. CONSTITUTION:A honeycomb layered body used is formed by winding and laminating wavy paper body having waves on one surface with 2.5-45 mm wavelength and 1.3-2.5mm wave height, and this paper body consists of an inorg. fiber paper of 0. 3-0. 6 apparent density, 30-180g/m2 basis weight and 0. 1-0. 3 mm thickness. This layered body is impregnated with a water glass soln., dried, and then dipped in acid. By the chemical reaction of water glass and acid, active silica gel having pores of 20-40Angstrom diameter distribution range and 300-600m2/gr surface area is chemically synthesized and coupled among fibers of the inorg. fiber paper and on the surface of the honeycomb layered body. The obtd. adsorbent has large efficiency of gas adsorption and small permeation resistance for gas in the micropores.
