- Steam methane reforming is a process that produces hydrogen gas from methane and steam. The reaction can be described by the following equations123:
- CH 4 + H 2 O (+ heat) → CO + 3H 2
- CH₄ (g) + 2H₂O (g) ⇌ CO₂ (g) + 4H₂ (g)
- 2 CH 4 + O 2 + CO 2 → 3 H 2 + 3 CO + H 2 O
- 4 CH 4 + O 2 + 2 H 2 O → 10 H 2 + 4 CO

Reforming for combustion engines is based on steam reforming, where non-methane hydrocarbons of low quality gases are converted to synthesis gas (H 2 + CO) and finally to methane (CH 4), carbon dioxide (CO 2) and hydrogen (H 2) - thereby improving the fuel gas quality (methane number). See more
