Conversion of $CO_2$ and $CH_4$ to Syngas by Making Use of Microwave Plasma Torch

전자파 플라즈마 토치를 이용한 이산화탄소와 메탄의 Syngas 합성

Carbon dioxide ($CO_2$) and methane (CH$_4$) are two major greenhouse Bases. $CO_2$is a stack gas of many industrial processes and the main product of the hydrocarbon combustion. There is recent research interest on the synthesis gas (syngas) formation from $CO_2$ and CH$_4$, via the following reaction: CH$_4$+$CO_2$longrightarrow 2H$_2$+$CO_2$, in order to reduce the greenhouse effects and to synthesize various chemicals, Preliminary experiments were conducted on the conversion of $CO_2$ and CH$_4$ to syngas by making use of a microwave plasma torch at atmospheric pressure. Conversion rates of $CO_2$and CH$_4$ to hydrogen (H$_2$), carbon monoxide (CO) and higher hydrocarbons were investigated using Gas Chromatography (GC) and Fourier Transform Infrared (FTIR). The experimental data indicate that the main products were H$_2$, CO and small amount of higher hydrocarbons, such as ethylene (C$_2$H$_4$).
