CATALYST FOR REMOVING HYDROCARBON AND HYDROCARBON REMOVAL METHOD

摘要

PROBLEM TO BE SOLVED: To provide an oxidizing catalyst with excellent oxidization performance and economic property capable of clearing even a gas containing sulfur oxide of a lower saturated hydrocarbon having two or more carbon atoms (particularly ethane and propane) by efficient oxidization with high catalytic activity.;SOLUTION: The catalyst is formed by carrying a zirconia carrier with platinum. In the catalyst, a ratio of platinum may be approximately 0.5-20 wt. prts. based on 100 wt. prts. of zirconia. The catalytic activity of the catalyst by containing the sulfur component. Therefore, the catalyst is may be further treated with sulfur oxide. The lower saturated hydrocarbon having two or more carbon atoms can be efficiently oxidized/removed with high catalytic activity by bringing the gas to be treated containing at least oxygen and the lower saturated hydrocarbon having two or more carbon atoms (ethane, propane, etc.) in contact with such a catalyst.;COPYRIGHT: (C)2005,JPO&NCIPI
