Abstract
The combined CaCO3-calcination and CH4-reforming process is investigated using concentrated solar energy as the source of high-temperature process heal. The thermodynamic equilibrium composition indicates the coproduction of time and syngas (H-2/CO molar ratio = 1) at above 1200 K and I bar. Exploratory experimental runs were carried Out with a 5 kW solar chemical reactor comprised of a windowed cavity-receiver containing it flow of CH4 with suspended CaCO3 particles and directly exposed to high-flux solar radiation. At an optimal reactor configuration, CaCO3 and CH4 conversions or 83% and 38%, respectively, were achieved during 11 min of irradiation at a solar concentration ratio of 1884 suns and a normal temperature Of 1223 K. Effecting Simultaneously both reactions in a single solar-driven reactor eliminates CO2 emissions derived from the separate fossil-fuel-based production of these two energy-intensive material commodities.
