Description

technical field

[0001] The invention relates to the technical field of catalyst preparation, in particular to a composite functional reforming hydrogen production catalyst and its preparation method and application. Background technique

[0002] The steam reforming hydrogen production technology is mature and low cost, and has an absolute advantage in industrial hydrogen production. The general steam reforming hydrogen production process includes several units: raw material pretreatment unit, steam reforming unit, high temperature and low temperature water gas conversion unit, CO removal 2 Purification unit and waste heat recovery unit, etc. However, since the steam reforming hydrogen production reaction is a reversible reaction with strong endothermicity, its reaction conditions are harsh, it is a production process with high energy consumption, and the overall reaction efficiency is low, and the purity of hydrogen produced is not high. The subsequent hydrogen purificatio...
