[Abstract]:Three different catalytic reaction mechanisms of methanol steam reforming for hydrogen production over Cu based catalyst were summarized, and the reaction temperature and methanol conversion were summarized. The effects of hydrogen selective CO selectivity and hydrogen yield on the deactivation of Cu-based catalysts were summarized. The main causes of deactivation of Cu-based catalysts were thermodynamic sintering, carbon deposition sintering, etc. The effects of different supports on the structure and thermal stability of catalysts were discussed.
