摘　　要：提出一种将光热协同太阳能燃料制备与集热技术相结合的新型太阳能有序转化综合利用系统。该系统通过光热协同反应将太阳能中紫外可见波段能量以化学能形式存储,并利用集热技术转化部分可见及红外波段能量为中温热能。采用CO;还原为光热协同目标反应,导热油为传热工质进行系统运行实验,实验结果表明:光热协同反应温度为290℃,产物CO产率为5.80μmol/g-cat,集热片温度为320℃,通过导热油吸热量计算得集热子系统辐射能量利用效率为59.7%。A novel solar energy comprehensive utilization system combining photo-thermal approach and heat collecting technology is proposed.The system stores the ultraviolet and visible energy in the form of chemical energy through photo-thermal reaction,and converts part of the visible and infrared energy to mid-temperature heat.Using CO;as raw material gas,and heat transfer oil as working fluid for system operation experiment.The results show that the photo-thermal reaction temperature is 290℃,and the product CO yield is 5.80μmol/g-cat.The temperature of heat-collecting sheet is 320℃and radiation energy utilization efficiency of heat collecting subsystem is 59.7%,which is calculated by the rising temperature of heat transfer oil.
