在18 wt. %的NiO/α-Al 2 O 3催化剂在1巴下在300-700 ℃的温度范围内存在。实验是在扩散限制条件和远离平衡条件的活塞流反应器中进行的。在gPROMS model builder 4.1.0（R）平台上开发了催化填充床反应器的一维非均相数学模型，并对SMR过程的数学模型进行了模拟，通过与实验值的比较验证了模型的正确性。模拟结果与实验结果吻合良好。考察了温度、压力、水蒸汽比等操作参数对燃料和水转化率（%）、H-2产率（wt. %）、反应温度和反应时间的影响。%的CH 4）和H-2纯度进行建模，并与平衡值进行比较。(C)2016作者由Elsevier Ltd代表Hydrogen Energy Publications LLC出版。
Kinetic rate data for steam methane reforming (SMR) coupled with water gas shift (WGS) over an 18 wt. % NiO/alpha-Al2O3 catalyst are presented in the temperature range of 300-700 degrees C at 1 bar. The experiments were performed in a plug flow reactor under the conditions of diffusion limitations and away from the equilibrium conditions. The kinetic model was implemented in a one-dimensional heterogeneous mathematical model of catalytic packed bed reactor, developed on gPROMS model builder 4.1.0((R)) The mathematical model of SMR process was simulated, and the model was validated by comparing the results with the experimental values. The simulation results were in excellent agreement with the experimental results. The effect of various operating parameters such as temperature, pressure and steam to carbon ratio on fuel and water conversion (%), H-2 yield (wt. % of CH4) and H-2 purity was modelled and compared with the equilibrium values.
