LYB - B Protective Agent for Sulfur Tolerant Shift Catalyst


1. Performance feature
    LYB-B Protective agent for Sulfur Tolerant Shift Catalyst is supporting developed protective agent for CO sulfur tolerant shift catalyst and has the feature of high mechanical strength, fine structure stability and high deoxidizing ability to desorbe or absorb the oxygen, tar and other impurities or poisons and a protection for CO sulfur tolerant shift catalyst. And it has a conversion activity for itself for prolonging the service life of catalyst.
