1, performance characteristics
LYB-A sulfur tolerant shift catalyst is a kind of special carrier and cobaltmolybdenum carbon monoxide containing new additives of sulfur tolerant shift catalyst. Apply to the coal, heavy oil and residual oil as raw material to produce thetransformation process flow of gas and city gas medium voltage (1 ~ 5.0MPa),especially suitable for using coal as raw material in ammonia plant usingsuppression.
The catalyst has high mechanical strength, good low temperature activity, easysulfidation and regeneration, alkali erosion rate is low, the advantages of simple preparation process. The service life of the catalyst and the conditions of use, LYB-A is expected service life is 3 ~ 8 years. The fresh catalyst active component ofcobalt, molybdenum in cobalt oxide, molybdenum oxide form, use first vulcanization,metal oxide into sulfide, sulfur vulcanization process gas can be used alone, can also be used curing agents curing. LYB-A sulfur tolerant shift catalyst composition is simple, does not contain harmful substances, the equipment and human bodyduring curing, water only generate a small and with the process gas discharge, noharm to equipment.
The physicochemical properties of 2, catalyst

4, packaging, storage and transportation
Catalyst for cardboard packaging, lined with plastic bag (or according to userrequirements packaging). Avoid scrolling should catalyst in the process of transportation, collision and vibration, so as to avoid crushing. , good packaging products should be stored in dry warehouse, can not be in contact with other chemicals, to prevent pollution, damp and broken.
