  • Publication number: 20070298958
    Abstract: There is provided a method for manufacturing a silicon carbide based honeycomb structure, the method using, as a part of a starting material, a recycled raw material recycled from a recovered material generated in a process for manufacturing the silicon carbide based honeycomb structure and derived from a starting material for a silicon carbide based honeycomb structure; wherein the recycled raw material is pulverized to have an average particle size of 10 to 300 ?m. According to the present invention, structure defects such as voids or coarse particles, which have been problems upon manufacturing a silicon carbide based honeycomb structure, are hardly formed, and a silicon carbide based honeycomb structure having excellent strength and uniform heat conductivity can be obtained. In addition, since a once kneaded material is used as a part of a starting material, the time for kneading can be shortened.

  • Publication number: 20070004591
    Abstract: An adsorbent comprising zeolite exhibiting a moisture adsorption of at least 28 wt. % at 25° C. under a partial pressure of water vapor of 5 Torr, and exhibiting a moisture adsorption difference of 15-25 wt. % between a moisture adsorption at 25° C. under a partial pressure of water vapor of 5 Torr and a moisture adsorption at 100° C. under a partial pressure of water vapor of 15 Torr. This adsorbent is produced by ion-exchanging an exchangeable cation in a zeolite, and then, heat-treating the cation-exchanged zeolite in an air or nitrogen stream, or with steam. The adsorbent exhibits a large moisture adsorption at ordinary temperature under a relatively low partial pressure of water vapor and a small moisture adsorption at a relatively low regeneration temperature, and thus, has an enhanced effective moisture adsorption, and is used for a zeolite-water heat pump system and an open cycle moisture adsorption-desorption system.
