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.

4. Packaging, storage and transportation
LYB-B protective agent for sulfur tolerant shift catalyst is packed in the fiber cans with inner plastic bags (or as per customers). It should avoid rolling, impacting and strenuous vibrating for no crushing. The final packed products should be put into the dry storehouses without contacting with other chemicals to keep from pollution, moisture and breaking.
