Development and demonstration of rotary-type solar chemical reactor

开发了“后热系统”和“交叉线性系统”两种新型太阳能集热系统，并合成了高活性陶瓷YSZ/Ni-铁氧体固溶体。快速加热释放αO_2的反应分为两个步骤：1）光子吸收及其弛豫过程形成过剩Frenkel结构（光反应）; 2）晶格氧在缺陷结构能驱动下生成O_2气体（暗反应）。研制了能连续进行光、暗反应的双柱太阳能反应器（3<rd>型）。在CSIRO的太阳能场进行了旋转反应器的现场试验。

New solar concentration systems of "post heating system" and "cross linear system" were developed, and highly reactive ceramics YSZ/Ni-ferrite solid solution was synthesized. TheαO_2 releasing reaction by rapid heating proceeds via two steps of 1) photon absorption and its relaxation process forming an excess Frenkel structure(light reaction), and 2) O_2 gas formation from lattice oxygen, which is driven by defect structure energy(dark reaction). The dual column solar reactor(3_<rd> model) was fabricated, with which the light and dark reactions can be occurred continuously. The field test of the rotary reactor developed was done at the solar field of CSIRO.
