摘要 在流化床反应器中进行甲烷临氧CO2重整制合成气反应。通过计算分析了催化剂颗粒在床层内的流化特性。对比实验表明,流化床反应器在催化剂活性、稳定性、自热过程以及催化剂积炭等方面均体现出比固定床反应器的优越性。在流化床反应器中进行的甲烷自热重整反应,甲烷的转化率接近热力学平衡值,床层温度梯度小于10℃,反应20 h后,催化剂表面无积炭。 Methane reforming with CO2 in the presence of oxygen was studied in a fluidized bed reactor. Fluidization behaviors of the catalyst particles in the reactor were investigated by calculating minimum fluidization velocity and terminal fluidization velocity. Comparative study between fluidized bed and fixed bed reactors showed that fluidized bed reactor was superior to fixed bed reactor especially in activity and stability of the catalyst, autothermal process and coke formation, with CH4 conversion approaching hermodynamict equilibrium, bed temperature gradient less than 10 ℃ and no coke formation after reaction for 20 h.
