甲烷干重整研究进展

摘要

甲烷干重整既可以天然气为原料,更适合以富含甲烷和二氧化碳的沼气为原料制富一氧化碳合成气或氢气,具有环境保护与资源利用的双重效益,受到国内外学者越来越多的关注.介绍了国内外学者近年来对甲烷干重整催化剂活性组分、载体、助剂、制备方法、操作参数、反应机理及积炭等方面开展的研究工作及新的等离子体干重整技术研究取得的进展.%Dry-reforming of methane can be used to prepare the carbon monoxide-rich syngas or hydrogen from carbon dioxide and the gases containing methane, such as natural gas and especially biogas which is rich in methane and carbon dioxide. Due to dry-reforming of methane has good environmental and economic benefit, it has become a current hot research topic. The research progresses in the catalysts, including active components, supports, promoters, method of preparation, operation parameter, reaction mechanism and deposition of carbon, and the new plasma dry-reforming of methane technology were introduced.
