WebbThe primary reformer is a typical steam methane reformer, and the secondary reformer is an autothermal reformer. Both reforming routes are governed by the steam reforming and water-gas shift reactions shown in Eqs. (1) and (2). The primary reformer operates at 40 bar and three discrete temperatures (800 °C, 850 °C, and 900 °C).
