摘要

Methane steam reforming coupling high-temperature exhaust gas as heat source for hydrogen production in an integrated reactor composed of the reforming channel and exhaust gas channel was studied with Computational Fluid Dynamics simulation. In this paper, the reactor performance, such as methane conversion rate, hydrogen yield, temperature, thermal efficiency, and reaction rate distribution were obtained with the optimization of inlet parameters and fluid flow in both channels. Results showed that the inlet temperature and velocity of the exhaust gas had an important effect on the reactor performance. However, its performance was not significantly affected by fluid flow modes and inlet feed reactant temperature. The reaction rate and heat flux were the highest at the reactor inlet, and then decreased along the flow direction. Simulation results could be used in the design and optimization of methane reforming reactors coupling waste heat utilization for hydrogen production.
