Abstract:

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．
