  Methanol in the temperature range of 220 to 300 degrees, cracking in the copper catalyst to generate hydrogen and carbon monoxide, carbon monoxide in the same catalyst under the reaction with steam to produce carbon dioxide, carbon dioxide is removed by pressure swing adsorption process, ultimately producing hydrogen.
  The reaction is: of CH3OH = 2H2 + CO, CO + H2O = H2 + CO2, and the total reaction: of CH3OH + H2O = 3H2 + CO2.
  
  Process principles
  
  The reaction is as follows:
  The main reaction: CH3OH = CO +2 H2 -90.7KJ/mol
  CO + H2O = CO2 + H2 +41.2 KJ / mol
  The overall reaction: CH3OH + H2O = CO2 +3 H2 -49.5KJ/mol
  Side effects: 2CH3OH = CH3OCH3 + H2O +24.9 KJ / mol
  CO +3 H2 = CH4 + H2O +206.3 KJ / mol
  Reaction transforming the gas by the heat exchanger, cooling, condensing its composition
  H2 CO2 CO CH3OH H2O
  Saturation of 73 ~ 74% 23 ~ 24.5% ~ 1.0% 300ppm
  The main reaction is an endothermic reaction, the use of external heat conducting oil. Conversion of gas by the heat exchanger, cooling, condensing into the scrubber tower kettle collection not transformed after methanol and water recycling
