Abstract

Conventional chemical processing methods, employed for transforming hydrocarbon mixtures into more valuable forms, are known to consume high amounts of energy and produce a substantial amount of greenhouse gas emissions. This paper investigates an alternative approach employing non-thermal plasma, in a controlled temperature environment, to synthesize higher-order hydrocarbons. The method examined in this paper, has the potential to reduce energy requirements. Effects of temperature and hydrocarbon chain length on liquid and gas production efficiency are studied. A comparative analysis of the different hydrocarbons as reactants underscores the promising attributes of n-octane in this application. With the proposed reactor configuration, the highest average liquid production efficiency was found in n-octane at 20 °C. Organic compounds with carbon chain lengths as large as 20 carbons where successfully synthesized in the reactor configuration when using decane as the reactant. The observed trends alluded to different chemical reaction pathways being prevalent in different temperature conditions.

期刊介绍： Publishing original papers on fundamental and applied research in plasma chemistry and plasma processing, the scope of this journal includes processing plasmas ranging from non-thermal plasmas to thermal plasmas, and fundamental plasma studies as well as studies of specific plasma applications. Such applications include but are not limited to plasma catalysis, environmental processing including treatment of liquids and gases, biological applications of plasmas including plasma medicine and agriculture, surface modification and deposition, powder and nanostructure synthesis, energy applications including plasma combustion and reforming, resource recovery, coupling of plasmas and electrochemistry, and plasma etching. Studies of chemical kinetics in plasmas, and the interactions of plasmas with surfaces are also solicited. It is essential that submissions include substantial consideration of the role of the plasma, for example, the relevant plasma chemistry, plasma physics or plasma–surface interactions; manuscripts that consider solely the properties of materials or substances processed using a plasma are not within the journal’s scope.
