  • This is the chemical reacting via various methods of mainly Lighter Hydrocarbons (Most often Methane , but Butane and Propane (And thus potentially LPG ? have been shown to work as well etc) (add citations from other tabs) ) to produce Syngas
  • If combined with the Water Gas Shift Reaction it can produce mostly Hydrogen as well


Steam Reforming

  • One of the most common methods
  • The reaction is typically conducted with a high pressure mixture of steam and methane are put into contact with a nickel catalyst
  • Can also be called "steam methane reforming" and thus abbreviated as SMR (not to be confused with Small Modular Reactor)

Carbon Dioxide Reforming

  • Also known as "Dry Reforming" (similar to "Dry Ice" meaning solid co2 )
  • Is challenging as the hydrogen that is produced tends to react with the carbon dioxide
  • Uses noble metal catalysts and/or nickel
  • More sources needed on this; much less straigforeward than steam reforming

Partial Oxidation

  • Abbreviated as POX
  • Uses a lean air mix to produce syngas
  • Can be thermal where it is essentially just a standard lean flame (TPOX), or catalytic (CPOX)where the temperature is lowered via catalysts
  • Has issues with soot and water vapor buildup suppsoedly (dump sources here)

Autothermal reforming

  • Autothermal reforming (ATR) uses both oxygen, and carbon dioxide or steam in a reaction with methane to form syngas
  • Thus can be varied:
    • The required H2/CO ratio is provided by manipulating the carbon dioxide or steam
