Catalytic reforming is a chemical process used to convert petroleum refinery naphthas distilled from crude oil (typically having low octane ratings) into high-octane liquid products called reformates, which are premium blending stocks for high-octane gasoline. The process converts low-octane linear hydrocarbons (paraffins) into branched alkanes (isoparaffins) and cyclic naphthenes, which ar… WebReforming (H0 = + 206 kJ/mol ) (1) 298 CO + H2O ⇔ CO2 + H2 ….. Shift (H0 = - 41 kJ/ mol ) (2) The formation of CO2 in the reforming reaction could be considered as an alternative to CO: CH4 + H2O ⇔ CO + 3 H2 (3) However, only two out of three equations are necessary to represent the overall equilibria.
