In the past few years several compact modular micro channel reactors were developed at the Institute for Micro Process Engineering of the Karlsruhe Institute of Technology. Target applications are small to medium-scale hydrogen production, chemical heat storage, and the provision of synthetic natural gas and synthetic fuels based on carbon dioxide and hydrogen from renewable electrical energy. More specifically, a micro-membrane reactor for methane steam reforming was demonstrated at a scale of 0.5 standard litres per minute of pure hydrogen. It integrates a thin palladium foil supported by a planar metal substrate via laser welding into an ultra-compact module. Modules can be stacked easily for capacity increase. A similar system is under development for dehydrogenation of methyl cyclohexane to toluene for storing heat at a temperature level of 350–400°C. An evaporation-cooled micro packed bed reactor for methanation of carbon oxide mixtures originating from a solid oxide electrolyser was demonstrated at a scale of 5 standard litres of methane per minute. The system is currently scaled-up to 100 kWth methane output. Finally, a similar reactor system was developed for Fischer–Tropsch synthesis and demonstrated in a scale of 0.2 kg of liquids per hour. The technology is now being commercialized by the KIT spin-off INERATEC GmbH.

微型和微型膜反应器,用于化学能转化的高级应用

在过去的几年中,卡尔斯鲁厄技术学院的微过程工程研究所开发了几种紧凑的模块化微通道反应器。目标应用是中小型规模的氢气生产,化学储热以及基于可再生电能中的二氧化碳和氢气提供合成天然气和合成燃料。更具体地说,证明了用于甲烷蒸汽重整的微膜反应器的规模为每分钟纯氢0.5标准升。它通过激光焊接将由平面金属基板支撑的薄钯箔集成到超紧凑模块中。可以轻松堆叠模块以增加容量。正在开发一种类似的系统,用于将甲基环己烷脱氢为甲苯,以在350-400°C的温度水平下存储热量。以每分钟5标准升的甲烷规模证明了一种蒸发冷却的微型填充床反应器,用于甲烷化源自固体氧化物电解槽的二氧化碳混合物。该系统目前已扩大到100 kW沼气产量。最后,为费-托合成工艺开发了类似的反应器系统,并证明了每小时可处理0.2千克液体的规模。现在,该技术已由KIT衍生公司INERATEC GmbH商业化。
