Abstract

This is a PDF file of an unedited manuscript that has been accepted for publication. As a service to our customers we are providing this early version of the manuscript. The manuscript will undergo copyediting, typesetting, and review of the resulting proof before it is published in its final form. Please note that during the production process errors may be discovered which could affect the content, and all legal disclaimers that apply to the journal pertain. . The effect of methane addition on the electrical discharge and the reaction pathways are discussed. Highlights:• Treatment of HFC-134a with methane in a non-equilibrium plasma is investigated.• The reaction mechanism includes experimental data and quantum chemical analyses.• The targeted products from the treatment of HFC-134a are fluoropolymers.* email: eric.kennedy@newcastle.edu.au, phone: +61 2 4985-4422, fax: +61 2 4921-6893 2• NMR and FTIR spectroscopic analyses reveal that the polymers are random copolymers.

Experimental Study on the Reaction of CCl3F and CH4 in a Dielectric Barrier Discharge Nonequilibrium Plasma Reactor

“…The entire reactor assembly was located inside a dedicated fume cupboard. A detailed description of the experimental facility can be found in our earlier publications. − …”

A comprehensive review of contemporary strategies and approaches for the treatment of HFC‐134a

“…35 Various research has been carried out in numerous studies on different methods of plasma discharge, including arc plasma, 36 shock wave, 37 microwave plasma discharge, 38 water plasma, 39 and dielectric barrier discharge. 40 Ohno et al 36 operated arc plasma with air and water for the decomposition of waste HFC-134a with the decomposition rate of 99.99% under optimum conditions. Reaction (3) demonstrates the chemical destruction of HFC-134a by arc plasma.…”

“…Furthermore, Fig. 2 40 illustrates the reaction mechanism of plasma technology that improved the destruction by a novel advanced reactor with the assistance of methane. This showed HFC-134a decomposition and the reaction pathway of CH 4 when added to the reaction of HFC-134a.…”
