Abstract

Solar thermochemical conversion processes offer a promising pathway for converting sunlight into clean, sustainable, and carbon-neutral fuels. A solar chemical reactor is one of the most essential components that utilizes concentrated solar energy to drive chemical reactions. In this study, a novel hybrid solar reactor is designed, fabricated, and tested to assess its thermal performance for the purpose of studying the solar thermochemical conversion processes in Thailand for the first time. It was performed under different heating modes regarding solar heat and/or electrical heat, with the aim to support day-and-night operation and variations in solar radiation conditions. The reactor was experimentally tested under on-sun, off-sun, and hybrid conditions using air as a heat transfer fluid. As a result, with one kWth solar thermal power input absorbed, the solar reactor achieved high temperatures exceeding 500 °C from the hybrid system while the reactor absorption efficiency was found to be 4%. The reactor demonstrated the possibility and reliability of performing solar thermochemical conversion processes under day-and-night and unstable solar radiation conditions.
用于太阳能热化学过程的新型混合反应器的热性能评估
太阳能热化学转换过程为将太阳光转化为清洁、可持续和碳中性燃料提供了一条前景广阔的途径。太阳能化学反应器是利用集中的太阳能驱动化学反应的最基本组件之一。本研究设计、制造并测试了新型混合太阳能反应器,以评估其热性能,从而首次在泰国研究太阳能热化学转换过程。该反应器在太阳热和/或电热的不同加热模式下运行,目的是支持昼夜运行和太阳辐射条件的变化。以空气为传热流体,在日照、非日照和混合条件下对反应器进行了实验测试。结果表明,在吸收 1 千瓦时太阳能热输入的情况下,太阳能反应器从混合系统中获得了超过 500 ℃ 的高温,而反应器的吸收效率为 4%。该反应器证明了在昼夜和不稳定太阳辐射条件下进行太阳能热化学转换过程的可能性和可靠性。
