“…The CH 4 /CO 2 reforming reaction and its reverse CO/H 2 methanation reaction have ever been considered as the foregoers of thermochemical heat pipe applications in the storage and transmission of solar energy [29]. Solar reforming of methane with CO 2 has been investigated for more than 20 years [32][33][34][35]. The reactor is operated under the temperatures of 973-1133 K with a pressure of 0.35 MPa.…”

“…Methane reforming with carbon dioxide is a high temperature and highly endothermic process for solar thermochemical storage [1][2], and the product syngas as a mixture of CO and H 2 can be used as fuel for gas turbine power generator [3] and chemical raw materials. Tubular packed reactor is widely used for CH 4 /CO 2 reforming as well as many other reaction processes.…”

High temperature heat transfer and energy storage characteristics of methane reforming in tubular packed reactor are investigated under different operating temperature and inlet conditions. Experimental results show that the methane reforming in tubular packed reactor can efficiently storage high temperature thermal energy, and the thermochemical storage, sensible heat increment and heat loss are all very important. As the operating temperature increases, the thermochemical storage efficiency first increases for methane conservation rising and then decreases for heat loss rising. When the operating temperate is 800 o C, the methane conservation is about 80%, and the thermochemical storage efficiency and total energy efficiency can be higher than 45% and 70%. The methane reforming process is further simulated using the laminar finite-rate model and Arrhenius expression, and the simulated temperature distribution, methane conversion and energy storage efficiency totally have good agreements with experimental data.

“…The conversion of concentrated solar heat to chemical fuels has the advantage of producing energy carriers for storing and transporting solar energy. The direct thermochemical conversion of solar radiation energy is characterized by ideal high efficiency; its thermodynamic limit for the enthalpy storing is close to 100% [1,2]. Solar reforming of natural gas has been investigated as solar thermochemical processes by some worldwide research groups for more than two decades [3,4].…”
