Progress in CO_2 reforming of CH_4 by plasmas

Due to decrease of oil reserves and environmental problems caused by CO2 emission,the resource utilization of CO2 has been paid much attention.Plasma technology was considered to be one of potential ways for CO2 reforming of CH4.An overview of CO2 reforming of CH4 by different cold plasmas and thermal plasmas was presented.The thermal plasma with high specific enthalpy content,high temperature and high electron density could be better for the process of CO2 reforming of CH4 to syngas because of its advantages of large treatment capacity,easy scaling-up,not requiring catalyst and relatively high energy conversion efficiency and has potential for application in industrial production by further optimizing process and improving energy efficiency.
