First Claim
Patent Images
1. A method of removing sulfur compounds comprising at least one member selected from the group consisting of thiophenes, sulfides and mercaptans from a fuel gas containing the sulfur compounds, comprising the steps of:
- depositing silver in an amount of 13-21 wt % on a Na—
Y zeolite having a SiO2/Al2O3 molar ratio of from 4.8-6.0 by ion exchange and passing the fuel gas through an absorbent comprising the silver-deposited zeolite to remove the sulfur compounds therefrom.

Abstract
An adsorbent for removing sulfur compounds from sulfur compounds-containing fuel gas contains a zeolite ion-exchanged with Ag and has an excellent performance when used to remove sulfur compounds from the fuel gas, irrespective of the moisture concentration in the fuel gas, and a method for removing sulfur compounds from sulfur compounds-containing fuel gas by use of an adsorbent of the above-mentioned type. The zeolite is a Na—Y type zeolite.
