DESULFURIZATION ZEOLITE ADSORBENT AND MANUFACTURING METHOD OF THE SAME, DESULFURIZATION METHOD, DESULFURIZATION EQUIPMENT, AND FUEL CELL SYSTEM

摘要

PPROBLEM TO BE SOLVED: To provide a desulfurization zeolite adsorbent effective for removing sulfur compounds and a manufacturing method of the same, a desulfurization method, desulfurization equipment, and a fuel cell system. PSOLUTION: The desulfurization zeolite adsorbent containing Y-zeolite where Ag ion is exchanged of crystallinity of Y-zeolite where Ag ion is exchanged of 45 to 98%, if the crystallinity of Y-zeolite where Ag ion is not exchanged is assumed as 100 and the manufacturing method of the same, desulfurization method, desulfurization equipment, and fuel cell system are provided. The desulfurization zeolite adsorbent, even if a small amount of Ag is contained, has a significantly excellent sulfur compound adsorption performance because it has a higher crystallinity than that of a conventional one. Therefore, cheaper and more excellent desulfurization equipment can be configured if the sulfur compounds in fuel gas are removed by using the desulfurization zeolite adsorbent.
