LF113 High Temperature Shift Catalyst
LF113 High Temperature Shift Catalyst
LF113 high temperature CO sulfur tolerant shift catalyst is produced with coprecipitation process, using ferrous nitrate as the feed, replacing the conventional ferrous sulphate process, which greatly decreases the content of bulk sulfur in the catalyst. It has the characteristics of good low temperature activity, high mechanical strength, low bulk sulfur content, wide operating temperature, high sulfur resistance, good boiling water resistance, long service life.
