太阳能热化学过程需要开发在1000 - 1500°C下运行的高温太阳能反应堆，例如煤炭的太阳能气化和金属氧化物的热还原，作为两步水分解循环的一部分。在这里，我们建议将“内循环流化床”应用于有窗太阳能化学反应器，其中反应颗粒被直接照射。原型反应器是在实验室规模建造的，并证明了使用太阳模拟器的太阳模拟，集中可见光作为能源的煤焦CO2气化。通过太阳能模拟气化的焦炭获得了约12%的最大化学品储存效率。
Solar thermochemical processes require the development of a high-temperature solar reactor operating at 1000―1500°C, such as solar gasification of coal and the thermal reduction of metal oxides as part of a two-step water splitting cycle. Here, we propose to apply "an internally circulating fluidized bed" for a windowed solar chemical reactor in which reacting particles are directly illuminated. The prototype reactor was constructed in a laboratory scale and demonstrated on CO 2 gasification of coal coke using solar-simulated, concentrated visible light from a sun simulator as the energy source. About 12% of the maximum chemical storage efficiency was obtained by the solar-simulated gasification of the coke.
