| Technology | Advantages | Disadvantages |
| Steam reforming | Most extensive industrial experience Oxygen not required Lowest process temperature Best H2/CO ratio for H2 production | Highest air emission |
| Auto-thermal | Lower process temperature than POX Low methane slip | Limited commercial experience Requires air or oxygen |
| Partial oxidation | Decreased desulfurization requirement No catalyst required Low methane slip | Low H2/CO ratio Very high processing temperatures Soot formation/handling adds process complexity |
