Outline of Final Research Achievements

Plasma enhances chemical reaction rates since in plasma it is possible to form strong radical species on the interface of gas, liquid, plasma. In present study, using various plasma processes, (1) One-step phenol production from Water-Toluene or water-Benzene, (2) Synthesis of organic compounds by cross coupling method, (3) Synthesis of liquid hydrocarbon by Fischer-Tropsch（FT） reaction, are investigated. Although　cross coupling reaction can not be confirmed in the present conditions, the experimental results by DBD plasma suggest that phenol can be directly produced from a water-toluene or a water- benzene mixture, and one-step phenol production from 30% toluene solution is possible. In FT reaction by using plasma, it was found that a hydrocarbon with double bond was produced when methanol was decomposed by plasma, and a normal linear alkane was produced when ethanol was decomposed by plasma.
