FAQ

Frequently Asked Questions

Traditional steam reforming of fossil fuels is not considered green as it produces CO2. 'Green' status depends on using biogas or coupling it with carbon capture and storage (CCS).

Steam reforming uses only steam and external heat, while autothermal reforming combines steam with some internal combustion (oxidation) of the feedstock to provide the necessary heat.

Yes, the process can be applied to other hydrocarbons like naphtha, liquefied petroleum gas (LPG), or even biofuels, though methane from natural gas is the most common feedstock.

It is the dominant, most economical method for producing the vast quantities of hydrogen used in fertiliser manufacture, petroleum refining, and as a potential energy carrier.

A chemical process for producing hydrogen and carbon monoxide from hydrocarbons like methane, using steam.

Steam reforming is usually technical/scientific in register.

Steam reforming: in British English it is pronounced /stiːm rɪˈfɔːmɪŋ/, and in American English it is pronounced /stim rɪˈfɔrmɪŋ/. Tap the audio buttons above to hear it.

Learning

Memory Aids

Mnemonic

Think of STEAM cleaning a fossil fuel (REFORMing it) to break it into cleaner gases like hydrogen.

Conceptual Metaphor

REFORMING as transformative processing (like political reform changes a system, steam reforming changes a molecule).
