Methanation of synthesis gas in a solar chemical heat pipe
The reversible reaction CH4 + CO2 = 2H2 + 2CO is under investigation as a chemical heat pipe for storage and transport of solar energy. In this paper, the study of the back exothermic reaction, the methanation of CO-rich synthesis gas, is reported. Three different methanators were constructed and operated in a closed-loop, with the reforming products from the reaction carried out in the solar furnace. The best performance was obtained with a six-stage adiabatic methanator. The experimental results are compared with computer calculations, assuming equilibrium at each stage. The agreement between experimental and calculated results is satisfactory. Scale-up work on a 400 kW unit is in progress.
