Abstract

This study presents an efficient method to convert methane into valuable olefins using a Solid Oxide Fuel Cell (SOFC) membrane reactor. Methane, abundant in natural and shale gas, serves as a sustainable feedstock due to its favorable carbon-hydrogen ratio. The SOFC membrane reactor eliminates costly air separation units and safety risks associated with explosive methane-oxygen mixtures. A planar SOFC stack achieves over 30 % methane conversion, 40 % ethylene selectivity, and power generation capabilities. Optimization with mixed-conducting ceramics enhances electrical performance without compromising catalytic activity. The stack's scalability is demonstrated, with the 5-cell configuration surpassing the 2-cell setup. This innovative approach offers a sustainable solution to methane waste, producing high-value chemicals while reducing environmental impact.

在催化剂增强型平面固体氧化物燃料电池堆反应器中将甲烷直接氧化偶联成乙烯

本研究提出了一种利用固体氧化物燃料电池（SOFC）膜反应器将甲烷转化为有价值烯烃的高效方法。甲烷在天然气和页岩气中含量丰富，因其有利的碳氢比率而成为一种可持续的原料。SOFC 膜反应器消除了昂贵的空气分离装置和甲烷-氧气混合物爆炸带来的安全风险。平面 SOFC 堆实现了 30% 以上的甲烷转化率、40% 的乙烯选择性和发电能力。使用混合导电陶瓷进行的优化在不影响催化活性的情况下提高了电气性能。该堆栈的可扩展性得到了证明，5 个电池的配置超过了 2 个电池的设置。这种创新方法为甲烷废物提供了一种可持续的解决方案，在生产高价值化学品的同时减少了对环境的影响。
