Reduction operation parameters for hydrogen production catalysts using natural gas as a feedstock
Thread Content
We have here a hydrogen production facility that produces 400 cubic meters per hour, using natural gas as the raw material. I’m not quite understanding the process of catalyst reduction; if any of you know about this, please give me some guidance
Reply 1# *ouluo88: Generally, nickel-based catalysts are used, with alumina as the carrier. Natural gas and water vapor undergo catalytic conversion at high temperature and pressure to produce a mixture of hydrogen, carbon dioxide, and carbon monoxide; hydrogen is then obtained through purification. Among foreign manufacturers of catalysts, ICI is a notable example; in China, the Southwest Chemical Engineering Design Institute is involved in this field. The specific process parameters depend on the different brands of catalysts used.
It is about reducing nickel in its oxidized state back to nickel, as the oxidized form does not have catalytic properties.
