Heat treatment is performed for 0 minutes to obtain an adsorbent. The odorous gas purification rates of the honeycomb-shaped adsorbents of the above-mentioned Examples and Comparative Examples were measured by the following method. A heat-resistant glass reaction tube having an inner diameter of 30 mm was filled with 3.2 cc of the honeycomb adsorbent having a lattice shape of 200 cells / inch 2 obtained above, and air containing 10 ppm of hydrogen sulfide as a malodorous component was used at a space velocity of 300.
It was introduced into the reaction tube at a flow rate of 00 h −1 and the hydrogen sulfide purification capacity after 3 hours was determined.

の悪臭成分は減少することがわかる。From the above results, when comparing the hydrogen sulfide purification performance of the honeycomb-shaped adsorbent of Example 3 and the honeycomb-shaped adsorbent of the comparative example after 3 hours, the purification performance of the honeycomb-shaped adsorbent of the comparative example is shown in Example 3. It is lower than that of the honeycomb-shaped adsorbent. From this, it can be seen that the honeycomb-shaped adsorbent has a significantly reduced adsorption capacity when exposed to a high temperature higher than the heat resistant temperature of the adsorbent. Further, when the concentrations of hydrogen sulfide during heating of the honeycomb-shaped adsorbents of Examples 1 and 2, 3 and 4, 5, and 6, and 7 and 8 are respectively compared, the ones carrying platinum and palladium show low concentrations. This shows that the catalytic action reduces the malodorous components during desorption.
