Steam Reforming Catalyst For Producing Hydrogen

AM-2-412Q/AM-2-413Q steam reforming catalyst is suitable for the steam reforming process of producing hydrogen,methanol synthesis gas and ammonia synthesis gas from natural gas.

AM-2-412Q is installed in the upper half of the reformer tube, AM-2-413Q is installed in the lower half of the reformer tube.

AM-2-412Q/AM-2-413Q steam reforming catalyst has the characteristics of large geometric surface, low bulk density, good heat transfer effect, high catalyst activity, low bed resistance and high operating flexibility.

How to choose steam reforming catalyst?

Steam reforming process:

Application: Main industrial hydrogen production process, used in ammonia synthesis, methanol synthesis, iron ore reduction and hydrorefining of petroleum

Features: The reaction is strongly endothermic and limited by chemical equilibrium

Requirements: In order to achieve high conversion or yield, high temperature (700-1000°C) is required

Problem: The biggest problem with nickel at this temperature is sintering deactivation

But activity is not a problem because kinetic velocity at high temperature is sufficient

Because the positive reaction is strongly endothermic, heat transfer control is required

①　Use thin reaction tubes (10-20 cm) to ensure sufficient heat transfer area, while requiring sufficient length to ensure proper space velocity (>10000 hr-1)

②　Lower pressure drop with larger particles

③　Small pipe diameter, there are flow distribution problems, pipe diameter / particle size > 5-10

④　When the temperature is high, the speed is fast, and the effective selection factor is small

⑤　Selection of annular shape: not only ensures the void ratio of the bed, but also reduces the effective radius

⑥　Weighing some other factors, particle size = about 2 cm is appropriate

Because the forward reaction temperature is high, the steam reforming catalyst needs to have good thermal stability

①　Requires particles to maintain their physicochemical properties under reaction conditions

②　To avoid phase changes and fragmentation

③　Appropriate high melting point materials are required as carriers, such as MgAl2O4, CaAl2O4
