摘要
二甲醚是一种清洁燃料,有望取代传统汽车燃料以达到高效能低排放的目的。研究表明,在发动机中添加一定量氢气可有效提高二甲醚的燃烧性能,车载二甲醚重整制氢技术的研究迫在眉睫。本文总结和评述了二甲醚重整制氢技术的研究进展,包括二甲醚重整制氢的方法以及重整催化剂等,并简要分析了各种二甲醚重整方法应用于车载重整器的可能性,指出催化剂的新型制备方法与等离子体重整技术是今后二甲醚车载制氢的主要方向。
Dimethyl ether（DME）is one kind of clean fuels.It is expected to replace traditional fuels for vehicles in order to achieve high performance and low emission.Research shows that adding a certain amount of hydrogen into engine can improve the combustion characteristics of dimethyl ether,so onboard reforming of DME to hydrogen is an urgent technology.This article summarizes and comments on the research progress of dimethyl ether reforming to hydrogen,including the methods of dimethyl ether reforming and reforming catalyst,the possibilities of using various methods in reforming DME board restructuring are analyzed as well.It is pointed out that developing the new catalyst preparation methods and plasma-onboard reforming technology is one of the future directions of the onboard fuel reforming to hydrogen.
