Can AVANT High-Temperature Shift Catalyst Revolutionize Hydrogen Production Efficiency?

The carbon monoxide conversion reaction refers to the reaction where carbon monoxide reacts with water vapor to produce carbon dioxide and hydrogen gas. The reaction is represented as follows:

CO＋HO H＋CO+41.19kJ/mol

This equation depicts a typical gas-solid phase reaction, widely applied in industries such as ammonia synthesis, methanol synthesis, hydrogen production, carbonyl synthesis gas, and urban gas production.

The carbon monoxide conversion reaction is an exothermic reversible reaction that proceeds very slowly under normal conditions, far from meeting industrial production needs. However, with the action of conversion catalysts, the reaction rate can be significantly increased, and side reactions can be prevented or reduced.

According to the principle of chemical equilibrium, the higher the reaction temperature, the lower the equilibrium conversion rate of the conversion reaction. In adiabatic conversion reactors, to achieve a higher CO conversion rate, it is necessary to lower the temperature at the inlet of the catalyst bed as much as possible, so that the outlet temperature of the bed is as low as possible. This requires the catalyst to have excellent low-temperature activity.

To ensure that the conversion catalyst is not overly reduced, the operation must be carried out at a gas-to-vapor ratio exceeding the stoichiometric ratio. The higher the catalyst usage temperature, the higher the required gas-to-vapor ratio. If a catalyst with good low-temperature activity is used, the entire catalyst bed can be operated at a lower temperature, reducing the gas-to-vapor ratio required for the operation of the conversion system and saving steam consumption.

Integrating the AVANT high-temperature shift catalyst enhances the efficiency of convective steam reforming in hydrogen production. This catalyst facilitates the conversion of carbon monoxide to carbon dioxide and hydrogen, pivotal steps in hydrogen production. Leveraging its superior performance and thermal stability, the AVANT catalyst expedites reaction kinetics, resulting in increased hydrogen yield and diminished carbon monoxide emissions. By integrating the AVANT catalyst into steam reforming units, clients can achieve higher conversion rates and optimize overall hydrogen production efficiency.
