For the production of hydrogen, process gas is mixed with superheated steam at elevated temperatures of up to 1000°C (1832°F) in the presence of a catalyst. Excess process heat recovered is used to generate high-pressure superheated steam in a waste heat boiler system. There are very high requirements put on this system.

· Syngas is a group of fuel gases produced at high temperatures. Gases including hydrogen, methane, carbon monoxide, and carbon dioxide fall under this category. The main stages of gasification include dehydration (at temperatures of 100–200 °C), pyrolysis (at temperatures of 200–500 °C), combustion, and reduction.
