Plasma-chemical conversion of methane: a review

The development of energy-saving, environmentally friendly methods for methane (CH₄) conversion is a topical issue of modern science. This is determined by both the practical need to produce hydrogen, which is widely used today, and the fundamental need to understand the processes that occur during the implementation of a particular conversion method. The paper presents the main plasma-chemical methods for methane conversion. Particular attention is paid to methods where pulsed electron beams are used as plasma sources. The methane conversion methods were compared in several categories: energy consumption for CH₄ decomposition, degree of conversion, synthesis selectivity. This review contains useful information for specialists involved in the development of methods for producing hydrogen.

开发节能、环保的甲烷（CH₄）转化方法是现代科学的热点问题。这一需求既源于当下对广泛应用的氢气生产的实际需要，也基于对特定转化方法实施过程中反应机理的基础研究需求。本文介绍了甲烷转化的主要等离子体化学（plasma-chemical）方法，特别关注了以脉冲电子束作为等离子体源的技术路线。文章从CH₄分解能耗、转化率、合成选择性三个维度对各类方法进行了对比分析。本综述为从事氢气生产方法开发的专业人员提供了有价值的参考信息。
