Hydrogen is produced in the steam reforming of propane: CH«(g) + 3 H;O(v)– 3 CO(g) + 7 H:(g) The water-gas shift reaction also takes place in the reactor, leading to the formation of additional hydrogen: CO(g) + H;O(v) → CO:(2) + H;(g) The reaction is carried out over a nickel catalyst in the tubes of a shell-and-tube reactor. The feed to the reactor contains steam and propane in a 6:1 molar ratio at 125°C, and the products emerge at 800°C. The excess steam in the feed assures essentially complete consumption of the propane. Heat is added to the reaction mixture by passing a hot gas over the outside of the tubes that contain the catalyst. The gas is fed at 4.94 m³/mol C3Hs, entering the unit at 1400°C and 1 atm and leaving at 900'C. The unit may be considered adiabatic.
