摘要：
In this paper, thermochemical storage performance of methane steam reforming in tube reactor with true concentrated radiation from focused solar simulator was experimentally studied, and the effects of heat flux density and reactant flow rate on methane conversion and energy storage performance were analyzed. The results showed that methane conversion increased with the increasing of heat flux density, while chemical storage efficiency increased first and then decreased. In addition, methane conversion of the thermochemical energy storage system decreased with the increasing of the reactant flow rate, and the chemical storage efficiency increased first and then decreases with a peak. As central heat flux rises from 172.7 kW/m2 to 565.8 kW/m2 with flow rate of 10 L/min, methane conversion rises from 7.5% to 34.4%, and chemical storage efficiency first rises and then decreases with a peak of 12.3% at 285.6 kW/m2. © 2021, Solar Energy Periodical Office Co., Ltd.
