Abstract

Over the last decade, plasma catalysis has attracted considerable research attention as an emerging low-carbon technology. In plasma catalysis, stable molecules such as CO2, CH4, and N2 are activated by electron impact or electrical energy, thereby ushering in a low-temperature chemistry domain that departs from energy-intensive, heat-dependent systems. Moreover, renewable-energy-driven plasma technologies are expected to help realize power-to-X schemes. In this short review, fluidized bed (FB) reactors incorporated with dielectric barrier discharge (DBD) are explored as potential candidates for upscaling plasma catalysis systems without employing a numbering-up approach. To that end, a scaled-up FB-DBD reactor is conceptualized using CO2 methanation as a model reaction, followed by the validation of laboratory-scale FB-DBD reactors, which exhibit remarkably high feed gas conversion rates at temperatures lower than those of thermal catalysis units. Finally, certain salient conclusions and perspectives are presented.
等离子流化床及其可扩展性
在过去的十年中,等离子体催化作为一种新兴的低碳技术引起了广泛的研究关注。在等离子体催化中,稳定的分子如CO2、CH4和N2被电子冲击或电能激活,从而进入一个低温化学领域,与能量密集、热依赖的系统不同。此外,可再生能源驱动的等离子体技术有望帮助实现power-to-X计划。在这篇简短的综述中,结合介质阻挡放电(DBD)的流化床(FB)反应器作为升级等离子体催化系统的潜在候选者进行了探讨,而不采用编号方法。为此,以CO2甲烷化为模型反应,对放大的FB-DBD反应器进行了概念化,随后对实验室规模的FB-DBD反应器进行了验证,该反应器在低于热催化装置的温度下表现出显着的高原料气转化率。最后,提出了一些重要的结论和观点。
