Nonthermal plasma reactors and plasma chemistry

The main goal of this paper is focused in reviewing the last 22 years of the use of nonthermal plasma reactors as alternative technologies for the treatment of residual fluid substances, regarding the destruction of hazardous compounds or the synthesis of other valuable compounds. The electrical discharge processing has emerged as alternative plasma-based technologies. Electrical discharges can be produced in different forms, depending on the geometry of the reactor and the electrical power supply. The nonthermal plasma reactors were classified into: pulsed or DC corona discharge; silent discharge or dielectric barrier discharge; surface discharge; electrified packed-bed.
