This paper reports a numerical study on carbon dioxide dissociation using a microhollow cathode discharge (MHCD) plasma reactor. These reactors can produce non-equilibrium plasmas and can be a promising technology for converting carbon dioxide into valuable chemicals and renewable fuels. However, these applications are currently in their early stages. In order to understand the effects of major design and operational parameters on the reactor performance a MHCD system was modeled and simulated. In this study, different types of dielectrics including mica, alumina, acrylic and quartz were used, and applied DC voltage was varied from 250 to 10,000 V. First the operating voltage regions of this reactor were determined based on the breakdown thresholds of the dielectric and gas phase. Then, the effects of applied voltage on the discharge volume and power requirement of operation were determined. Results showed that the reactor with mica as the dielectric material showed the largest operating voltage range, as well as the highest power requirement. In addition, the discharge volume increased with applied voltage and it was possible to discharge about 96% of the gas in the MHCD reactor with mica at 10 kV.

Effects of reactor geometry on dissociating CO2 and electrode degradation in a MHCD plasma reactor Taylan, Onur; Pinero, Daniel; Berberoğlu, Halil (2018-08-01) This paper reports an experimental study on the effects of reactor geometry for dissociating carbon dioxide using a microhollow cathode discharge (MHCD) reactor, and the associated electrode degradation. A MHCD reactor consists of two hollow metal electrodes that are separated by dielectric material. The geometric reactor parameters studied were the dielectric material thickness and the diameter of the reactor hole. Dielectric thicknesses of 150, 300 and 450 mu m and discharge hole diameters of 200, 400 and...
Dissociation of carbon dioxide using a microhollow cathode discharge plasma reactor: effects of applied voltage, flow rate and concentration Taylan, Onur; Berberoglu, H. (2015-02-01) This paper reports an experimental study on dissociating carbon dioxide (CO2) using a microhollow cathode discharge (MHCD) plasma reactor operated at 1 atm. The MHCD plasma reactors can be a promising technology for dissociating gases, including CO2, as they do not require catalysts, they operate at around room temperature, and can be inexpensively built and operated. In this study, CO2 balanced with the carrier gas argon (Ar) was fed through the MHCD reactor, and parametric experiments were conducted to in...
Discharge of Carbon Dioxide Using a Non Thermal Plasma Reactor Taylan, Onur; Berberoglu, Halil (2013-12-21) This paper reports a numerical study on the discharge of carbon dioxide using a non-thermal dielectric barrier discharge (DBD) plasma reactor at ambient conditions. DBD plasma reactors have been used for various applications due to their ease of production, process control, operation at different conditions. The applications of DBD plasma reactors include discharge of gases. Carbon dioxide is a greenhouse gas formed as a byproduct of fossil fuel combustion. Use of DBD non-thermal plasma reactor can be a pro...
Dissociation of Carbon Dioxide Using a Microdischarge Plasma Reactor Taylan, Onur; Berberoglu, Halil (2014-04-02) This paper reports an experimental study on dissociation of carbon dioxide using a microdischarge plasma reactor at ambient conditions. Carbon dioxide contributes to more than 80% of the greenhouse gas emissions in United States. The microdischarge plasmas can be a very promising method in dissociating gases, including carbon dioxide, due to their lack of need for catalysts, operating at temperatures lower than conventional thermochemical dissociation processes and ease of operation. A microhollow cathode d...
Observation of Gate-Tunable Coherent Perfect Absorption of Terahertz Radiation in Graphene Kakenov, Nurbek; Balci, Osman; Takan, Taylan; ÖZKAN, VEDAT ALİ; Altan, Hakan; KOCABAŞ, COŞKUN (2016-09-01) We report experimental observation of electrically tunable coherent perfect absorption (CPA) of terahertz (THz) radiation in graphene. We develop a reflection-type tunable THz cavity formed by a large-area graphene layer, a metallic reflective electrode, and an electrolytic medium in between. Ionic gating in the THz cavity allows us to tune the Fermi energy of graphene up to 1 eV and to achieve a critical coupling condition at 2.8 THz with absorption of 99%. With the enhanced THz absorption, we were able to...
