<p>PURPOSE:To obtain a gas adsorbing filter having adsorbing power in a high temp. region as well as in a low and ordinary temp. region by sticking fine powder obtd. by grinding the leaves, stemps, barks, roots, flowers and fruits of dried plants to the surface of a spongy substrate having a network structure with an adhesive. CONSTITUTION:Fine powder of 1-150mu particle size obtd. by grinding the leaves, stemps, barks, roots, flowers and fruits of dried plants is stuck to the surface of a spongy substrate having a network structure with an adhesive to form a gas adsorbing filter. The fine powder is stuck to the surface of a carrier having a granular structure composed of activated carbon granules, resin balls, etc., of 0.5-20mm diameter with an adhesive to form a gas adsorbing material. Since adsorbing power is ensured in a high temp. region as well as in a low and ordinary temp. region, gas adsorbed on the gas adsorbing filter or material is hardly desorbed or released even when air contg. the gas is heated to a high temp.</p> |
