Hexane decomposition without particle emission using a novel dielectric barrier discharge reactor filled with porous dielectric balls

摘要

This study investigated the decomposition of n-hexane in 15% O-2 (N-2 balance) in dielectric barrier discharge (DBD) reactors filled with three different kinds of dielectric balls, viz, quartz, less porous, and porous alumina balls. Products of n-hexane decomposition were analyzed by using a gas chromatograph (GC), gas chromatography-mass spectrometry (GC-MS), Fourier-transform infrared (FTIR) spectroscopy, and scanning mobility particle sizer (SMPS). The main products of n-hexane decomposition are CO, CO2, and liquid particles. The DBD reactor filled with porous alumina balls can completely adsorb the liquid particles and reduce particle emission. GC-MS and FTIR analysis results show that the liquid particles mainly compose 3-hexanone and 2-hexanone. (C) 2015 Elsevier B.V. All rights reserved.
