<p>PROBLEM TO BE SOLVED: To provide a highly durable sulfur compd. adsorbent capable of efficiently adsorbing and removing sulfur compds. from a gas contg. relatively small amts. of such malodorous sulfur compds. as hydrogen sulfide, mercaptanes and sulfides and the balance hydrocarbons or further from a gas such as air contg. the malodorous sulfur compds. SOLUTION: This sulfur compd. adsorbent is formed by depositing at least one kind of element selected from a group consisting of Ti, Zr, Fe, Cu, Ce and La and at least one kind of element selected from a group consisting of Pt, Au and Pd on the manganese oxide having 250m<2> /g specific surface and 37±1 deg. angle (2θ) of diffraction at the diffraction peak as the maximum intensity in X-ray diffraction.</p> |
