SULFUR COMPOUND ADSORBENT AND SULFUR COMPOUND REMOVING METHOD

摘要

PROBLEM TO BE SOLVED: To effectively remove the sulfur compd. in an atmosphere where an oxygen concn. is low for a long period by incorporating zeolite contg. any of faujasite type zeolite,βtype zeolite and L type zeolite and an inorg. binder into an adsorbent. SOLUTION: This adsorbent comprises the zeolite contg. any of the faujasite type zeolite designated as X type or Y type, theβtype zeolite and the L type zeolite and the binder, such as silica sol. The adsorbent preferably contains such zeolite at 50 to 90 wt.%. The sufficient adsorption capability is not obtainable at <=50 wt.%. The amt. of the binder decreases and the degradation in the strength as a molding and the degradation in the adhesion property when the adsorbent is formed as a film are significant at >=90 wt.%. The sulfur compd. may thus be adsorbed away by the zeolite even in the atmosphere where the oxygen concn. is low. In addition, the regeneration by heating is possible.
