Patent number: 10625238Abstract: Provided is a water-resistant sulfur compound adsorbent having a crushing strength that is less likely to be reduced even when used in a process including moisture. A certain amount of cellulose derivative is contained in the sulfur compound adsorbent containing a copper component for adsorbing a sulfur compound. This imparts water resistance to the adsorbent. As a result, it is possible to obtain the water-resistant sulfur compound adsorbent having the crushing strength that is less likely to be reduced even when used in the process including moisture.Type: GrantFiled: May 31, 2018Date of Patent: April 21, 2020Assignee: JGC CATALYSTS AND CHEMICALS LTD.Inventors: Chihiro Kojima, Takahiro Yashima, Kaoru Takahashi, Atsushi Okita, Kazunori Honda
