Estimation of energy consumption for process of CO_2 reforming of CH_4 to syngas by thermal plasma

Taking the syngas needed to produce methanol as reference and conversing the different energy consumed in the preparation process into primary energy,the energy consumption of CO2 reforming of CH4 by combination of thermal plasma and catalyst was analyzed,and compared to that of traditional steam reforming.Results of the analysis based on the achieved results of the finished experiments showed that the energy consumption of the two processes was similar,but the former could reduce the consumption of natural gas and the emission of CO2.As a developing technology,if the process energy efficiency was further improved,CO2 reforming of CH4 to produce syngas could achieve free-carbon,even negative-carbon emission.Therefore,it had an expectable industrial application prospect.
