Description

technical field [0001] The invention relates to hydrogen preparation technology, in particular to a method and device for preparing hydrogen-rich gas by plasma reforming. Background technique [0002] At present, methanol reforming hydrogen production technology is relatively mature in hydrogen production technology. There are two technologies for hydrogen production by methanol reforming, one is steam reforming of methanol, and the other is partial oxidation reforming of methanol. Chen Bing et al. in the "Research on Hydrogen Production by Steam Reforming of Methanol" published in "Natural Gas Chemical Industry" 2000, 25(2): 1-3, believed that it is a strong endothermic reaction. In the presence of a catalyst, The reaction temperature is 260-500° C., and the pressure is 1-1.5 MPa. The problem is that the structure of the reactor is complex and the reaction conditions are harsh. Zhang Xinrong et al. in "Battery" 2002.Vol.32, No: 2.107~109 "Resear...
