Abstract:

Solar energy is the most abundant clean energy in the world, and is regarded as the key to solve the problem of fossil energy shortage. However, the intermittentity of solar energy largely restricts its use scenarios, and the thermochemical process of solar energy can effectively mitigate the impact of solar intermittentity. In the process of solar thermochemistry, the performance of the reactor directly affects the effect of the reaction. Taking the solar methane reforming process as an example, three types of methane reforming were introduced, and their advantages and disadvantages and engineering applications were introduced, respectively. Then, several common solar methane reforming reactors were briefly described in terms of structure, working principle and research progress. It included the introduction of the most common cavity reactor, membrane reactor, rotating reactor, fluidized bed reactor and other novel ones. In conclusion, the author proposes that the next stage of research on solar methane reforming reactor should focus on the design of multi-functional reactor and the promotion of cross-disciplinary research.

摘要：

太阳能是世界上最丰富的清洁能源，被看作是解决化石能源短缺问题的关键。但是太阳能的间歇性很大程度上制约了其使用场景，太阳能热化学过程可以有效缓解太阳能间歇性带来的影响。在太阳能热化学过程中，反应器的性能直接影响了反应的效果。本文以太阳能甲烷重整过程为例，首先介绍了3种甲烷重整类型，分别介绍了其优缺点和工程应用。然后从结构、工作原理以及研究进展等方面简述了几种目前常见的太阳能甲烷重整反应器。包括对目前最常见的腔式反应器、膜反应器、旋转式反应器、流化床反应器和其他新颖反应器的介绍。最后，提出下一阶段太阳能甲烷重整反应器的研究重心应放在设计多功能于一体的反应器和促进多学科交叉研究上。
