Abstract

Hydrocarbon chains produced as byproduct of natural gas extraction and petrochemical processing can be valorised into syngas/H₂ and oxygenated fuels in a modular fashion through electrified modular plasma reactors. A plethora of configurations is available for light hydrocarbons reforming, with cold plasma assemblies emerging as the favourite option for both gas-phase and biphasic gas/liquid set-ups. Accurate control of dehydrogenation or partial oxidation reactions is provided by the implementation of a catalyst or through microreactor technology. On the contrary, warm plasma reactors are more suitable for reforming of gasoline/diesel chains, promoting higher throughput of H₂ per energy input. This reaction route does not necessarily require the deployment of a catalyst, hence making these systems more suitable for modular, decentralized processes. Online diagnostic techniques shed light on the reaction mechanism, where solid carbon deposits embody a low-value byproduct.

天然气开采和石化加工过程中产生的副产品碳氢链可以通过电气化模块化等离子体反应器，以模块化方式转化为合成气/H2 和含氧燃料。轻烃重整有多种配置可供选择，其中冷等离子体组件是气相和双相气/液装置中最受欢迎的选择。通过使用催化剂或采用微反应器技术，可对脱氢或部分氧化反应进行精确控制。相反，温等离子体反应器更适用于汽油/柴油链的重整，可提高单位能量输入的 H2 产量。这种反应途径不一定需要使用催化剂，因此这些系统更适合模块化、分散式工艺。在线诊断技术揭示了反应机制，其中固体碳沉积物是一种低价值的副产品。

期刊介绍： Publishing original papers on fundamental and applied research in plasma chemistry and plasma processing, the scope of this journal includes processing plasmas ranging from non-thermal plasmas to thermal plasmas, and fundamental plasma studies as well as studies of specific plasma applications. Such applications include but are not limited to plasma catalysis, environmental processing including treatment of liquids and gases, biological applications of plasmas including plasma medicine and agriculture, surface modification and deposition, powder and nanostructure synthesis, energy applications including plasma combustion and reforming, resource recovery, coupling of plasmas and electrochemistry, and plasma etching. Studies of chemical kinetics in plasmas, and the interactions of plasmas with surfaces are also solicited. It is essential that submissions include substantial consideration of the role of the plasma, for example, the relevant plasma chemistry, plasma physics or plasma–surface interactions; manuscripts that consider solely the properties of materials or substances processed using a plasma are not within the journal’s scope.
