TYZ412Q/TYZ413Q catalyst is a group of nickel as the active component. It is suitable for natural gas as feed, steam conversion to produce industrial hydrogen, ammonia synthesis gas, methanol synthesis gas. TYZ412Q is loaded in front part of tube. TYZ413Q is loaded in back of tube. Both are loaded in a certain proportion or adjusted according to the actual situation.   TYZ412Q/TYZ413Q catalyst has the characteristics of large geometric surface, small bulk density, good heat transferring, high activity, small pressure drop and large range of operation conditions.
