利用太阳能热能生产高温燃料，有可能显著减少我国当前经济对化石燃料的依赖。在过去的二十年里，太阳能驱动的用于生产氢气和合成气的热化学反应器的开发取得了显著的进展，因为它们是交通、家庭和工业应用的很有前途的能源载体。然而，与传统的热化学反应过程相比，太阳能具有特殊性--高热流密度和由于日照起伏而导致的频繁的热瞬变--而传统的工业热化学反应器通常不适合于太阳能驱动的反应堆。因此，为了实现高效的太阳能驱动的热化学过程，有必要对反应堆设计进行太阳能特有的修改。在太阳能热化学反应堆中，将颗粒固体原料太阳能加热到高温的方法大致可分为太阳能“直接”和“间接”吸收反应堆。在涉及固体粒子在高温下反应的太阳能热化学反应过程中，如“太阳能与金属氧化物两步分解水”和“太阳能气化”，已经发展了各种类型的太阳能直接和间接吸收粒子反应堆。本文综述了用于上述太阳热化学过程的太阳粒子反应堆的最新进展。
Utilization of solar thermal power for high temperature fuel production has the potential to significantly reduce the fossil fuel dependence of our current economy. Over the past two decades, remarkable progress has been made in the development of solar driven thermochemical reactors for the production of hydrogen and syngas as they are promising energy carriers for transportation, domestic and industrial applications. However, there are solar peculiarities in comparison to conventional thermochemical processes – high thermal flux density and frequent thermal transients because of the fluctuating insolation-, and conventional industrial thermochemical reactors are generally not suitable for solar driven reactors. Therefore, solar-specific modifications of reactor design are necessary to realize efficient solar driven thermochemical processes. In solar thermochemical reactors, the methods for solar-heating particulate solid feedstock to high temperatures can be broadly classified as solar “directly” and “indirectly” absorbing reactors. On solar thermochemical processes involving reacting solid particles at high temperatures, such as “solar two-step water splitting with metal oxides” and “solar gasification”, various types of solar directly and indirectly absorbing particle reactors have been developed. In this review, recent development of solar particle reactors for the above solar thermochemical processes is described.
