A petroleum refining process, using employing catalysis, in which heat and pressure are used to cause cracking and isomerization of the hydrocarbon molecules in low-octane petroleum fractions. The reformed hydrocarbons have higher octane numbers than the original material.

chemical cracking operation of a hydrocarbon or alcohol molecule so that it can be transformed into its major components

a refining process wherein short-chain molecules in certain crude distillation products are chemically recombined (reformed) by means of heat, pressure, and, usually, catalytic reaction to form higher-value long-chain-molecule compounds.

A chemical process in which hydrogen containing fuels react with steam, oxygen, or both to produce a hydrogen-rich gas stream.

See Platinum Reforming, Steam Reforming.

Reforming is the process of producing a hydrogen-rich gas stream for eventual use in a fuel cell from a feedstock.
