“…Tomishige [39] repeated the previous work and reported the same results. Khajeh et al [16,40] used a 1D model to simulate a conventional fluidizedbed trireformer (FTR). They assumed that heat and mass transfer along the radial axis are negligible.…”

Three models were developed for a conventional fluidized‐bed reactor and a cocurrent and a countercurrent membrane fluidized‐bed reactor for methane trireforming. Firstly, the effects of the operating parameters on the reactor performance were assessed. Then, a single‐objective optimization was established. Finally, a membrane was added to the reactor to improve the reactor performance. The simulated results illustrate that the reaction rates are highest near the reactor entrance due to the high volume fraction of the dispersed phase and the existence of a hot zone. Moreover, the optimization process indicates that the maximum H2 yield in the conventional fluidized‐bed reactor is obtained when the inlet temperature, inlet flow rate, and H2O/CH4 ratio, are 804 °C, 3.6 × 105 L h−1, and 2.5, respectively.
