Atmospheric pressure dielectric barrier discharge plasma operating in tetramethyltrisiloxane (L3)-helium gas mixture was studied as a prospective method for the reformation of the organosilicon compounds in the carrier stream. L3 belongs to a family of siloxanes present as trace contaminants in landfill gas limiting the application of landfill gas for energy applications. It was found that with dielectric barrier discharge, precipiates out L3 from the carrier stream in the form of a white residue on the reactor walls. Nuclear magnetic resonance and gas chromatograph mass spectroscopy was used to calibrate and determine the mole ratio of L3 in dodecane. 40% reduction in the amount of L3 present was achieved within 20 minutes.
