Abstract
CeO2 has been shown as a prominent oxygen carrier for two-step solar thermochemical (STC) CO production owing to its thermal stability and rapid reaction kinetics. However, the current two-step CeO2-based STC system suffers from a large temperature swing, leading to large heat loss as well as inconsecutive operation. To better the above metrics, the isothermal continuous STC CO production based on CeO2 is researched within our tubular reactor. The produced CO concentration is found to increase gradually at the first hour and then remain about 550 ppm for more than 8 h. The obtained amount of CO is about 14.4 mL g–1h –1, much larger than those reported before. The effects of temperature, flow rate and partial pressure on CO2 conversion ratio (χCO2) and solar-to-fuel energy efficiency (ηsolar-to-fuel) are also studied, underscoring the advantage of continuous operation and importance of avoiding excessive CO2 input. In addition, with the correction of experiment temperature, our calculated ηsolar-to-fuel is about 1.85%, an evident improvement compared to previous isothermal systems. Moreover, the non-integer CO2-splitting kinetic characteristics as well as its explicit equation are revealed, providing significant references for CO production regulation and solar reactor design.
