The Penex process is a continuous catalytic process used in the refining of crude oil. It isomerizes light naphtha (C 5 /C 6 ) into higher-octane, branched C 5 /C 6 molecules. It also reduces the concentration of benzene in the gasoline pool. It was first used commercially in 1958. Ideally, the isomerization catalyst converts normal pentane (nC5) to isopentane (iC5) and normal hexane (nC6) to 2,2- and 2,3-dimethylbutane. The thermodynamic equilibrium is more favorable at low temperature.
