- Description
- The effect of methane on the conversion of HFC-134a (CF₃CH₂F) in a dielectric barrier discharge non-equilibrium plasma reactor was examined. Reactions were conducted in an argon bath gas and in the absence of oxygen and nitrogen. The products of the reaction include H₂, HF, CHF₃, CH₂F₂, C₂H₆, C₃H₈, C₂H₃F, CHF₂CHF₂, C₂H₄F₂, C₃H₇F as well as a polymeric solid deposit. The polymeric materials are predominantly fluorine containing random copolymers, which can be categorised as fluoropolymers, constituted from various functional groups including CF₃, CF₂, CHF, CHF₂, CH₂F, CH₂ and CH₃. While the presence of methane in the feed stream reduces the conversion level of CF₃CH₂F, it also modifies the polymer architecture. The addition of 1.25% methane with 12.5% CF₃CH₂F in an argon bath gas at 100cm³min-1 feed rate reduces the conversion of CF₃CH₂F from 74.5% to 46.8% and increases the formation of HF from 1500µmolh-1 to 2640µmolh-1. The effect of methane addition on the electrical discharge and the reaction pathways are discussed.
