Abstract

In this study, a plasma-chemical method of methane conversion with CO₂ was considered as a potential means of producing hydrogen while simultaneously reducing carbon dioxide emissions. In order to achieve this, a series of experiments were conducted in order to evaluate the composition of the resulting fusion gas and the arc parameters. During the course of this work, it was found that modifying the volume of hydrogen present during the reaction resulted in an increase in the average mass temperature, which in turn led to an increase in the electrical conductivity of the arc. This finding suggests that the electrical parameters of the arc can be employed to estimate the quantity of hydrogen present in the resulting fusion gas.
