- Abstract
The performance of 1,1,1,2-tetrafluoroethane or HFC-134a decomposition and the formation of byproducts in a dielectric barrier discharge plasma reactor were studied with different packing systems such as α-AlO (porous and nonporous), γ-AlO (porous) and ZrO (nonporous). Experimental variables such as reactor temperature, initial HFC-134a concentration and oxygen levels were chosen for the performance analysis. Among the packing systems, the porous γ-AlO and α-AlO decomposed HFC-134a much more effectively than the nonporous α-AlO and ZrO. The combination of the plasma with the porous γ-AlO was found to cover a wide range of initial concentration. The decomposition efficiency tended to increase with the addition of oxygen up to 2 %, but further increase in the oxygen led to a decrease. As well as carbon oxides (CO and CO), significant amounts of unwanted byproducts such as COF and CF were also identified in the effluent gas with the nonporous α-AlO and ZrO. On the contrary, with the porous γ-AlO and α-AlO, such unwanted byproducts were considerably suppressed, enhancing the formation of CO and CO.
