CO_2 management technology is one of the most important issues for the global environment. This paper describes the feasibility experiment that CO_2 can be reformed by direct conversion into fuel-like species with the aid of plasma reactions. Here, (CO_2+H_2+Ar) is discharged into an expansion chamber rising a plasma reaction furnace and the chemical species produced by plasma direct mass conversion are detected by a combined time-of-flight and mass spectrometer technique. As the result, fuel-like species such as CO, CH_4, and CH_3OH are gained. And the paper describes quantum chemical analysis using an ab initio Molecular Orbital method to know the microscopic mechanisms of plasma-assisted mass-conversion from (CO_2+H_2O) into CH_3OH. As a result, we have made clear great contribution of H_2O in the process.
