“…The experimental setup consisted of a cylindrical DBD reactor, a power supply, a mass flow controller, a cold trap, and a diagnostic system which characterized the electrical properties of the power supply. The experimental setup is described in detail in a previous work 19. At first, the bottle of the feed was put in a water bath to increase the temperature of the feed to less than the evaporation temperature of the feed contents.…”

“…At the end of each experiment, coke was not attached to the electrodes' surfaces but a small amount of brownish liquid stain appeared on the glass surface inside the plasma reactor and was not counted in the calculation of yield data. An important point to be kept in mind is that the use of a DBD reactor eliminates coke formation when compared to conventional cracking which is due to the non‐thermal characteristic of the discharge 19, 21.…”

Pyrolysis fuel oil cracking by low-temperature plasma was investigated in a dielectric barrier discharge reactor at ambient pressure. The promoting effect of methane and ethane in the formation of products was evaluated by altering the working gas from methane to ethane. In addition, the production of hydrocarbons and hydrogen was analyzed. The main parameters were working gas type, flow rate, and applied voltage. Increasing the applied voltage enhanced the production rate of valuable petrochemical compounds like gas and liquid. Alteration of the working gas flow rate led to a higher production rate of H 2 , C 2 , C 3 , and C 4 . Chemical investigations were performed by optical emission spectroscopy of plasma and the main mechanisms are described.

Biofuels can be produced through a conventional catalytic cracking system and/or a hybrid catalyticplasma cracking system. This paper was focused on studying effect of Na + ion exchange to HY-Zeolite catalyst on catalyst performance to convert palm oil into biofuels over a conventional continuous fixed bed catalytic cracking reactor and comparing the catalytic cracking performance when carried out in a continuous hybrid catalytic-plasma reactor. The catalysts were characterized by X-ray Diffraction (XRD) and Bruneuer-Emmet-Teller (BET) surface area methods. The biofuels product were analyzed using Gas Chromatography-Mass Spectrometry (GC-MS) to determine the hydrocarbons composition of biofuels product. From the results, ion exchange process of Na + into HY-Zeolite catalyst decreases the catalyst activity due to decreasing the number of active sites caused by blocking of Na + ion. The selectivity to gasoline ranges achieved 34.25% with 99.11% total conversion when using HY catalyst over conventional continuous fixed bed reactor system. Unfortunately, the selectivity to gasoline ranges decreased to 13.96% and the total conversion decrease slightly to 98.06% when using NaY-Zeolite catalyst. As comparison when the cracking reaction was carried out in a hybrid catalytic-plasma reactor using a spent residual catalytic cracking (RCC) catalyst, the high energetics electron from plasma can improve the reactor performance, where the conversion and yield were increased and the selectivity to lower ranges of hydrocarbons was increased. However, the last results were potential to be intensively studied with respect to relation between reactor temperature and plasma-assisted catalytic reactor parameters.

“…Some researchers in the past have studied the use of non-thermal plasma-liquid reforming of hydrocarbons oils for H 2 production including the use of corona discharge [6][7][8][9][10], dielectric barrier discharge [11][12][13] and gliding arc discharge [14,15]. However, no attention has been given to the plasma-liquid interaction or the chemistry taking place in the hydrocarbon oil during plasma treatment.…”

Abstract:The degradation of liquid dodecane was studied in a gliding arc discharge (GAD) of humid argon or nitrogen. A batch or recirculating configuration was used. The products in the gaseous and liquid phase were analysed by infrared and chromatography and optical emission spectroscopy was used to identify the excited species in the discharge. The best degradation performance comes from the use of humid N 2 but a GAD of humid argon produces fewer gas-phase products but more liquid-phase end-products. A wide range of products such as heavier saturated or unsaturated hydrocarbons both aliphatic and aromatic, and oxidation products mainly alcohols, but also aldehydes, ketones and esters are produced in the liquid-phase. The recirculating treatment mode is more effective than the batch mode increasing the reactivity and changing the product selectivities. Overall, the study shows promising results for the organic liquid waste treatment, especially in the recirculating mode.
