An integrated plasma-Li/MgO system is efficient for the oxidative conversion of hexane. In comparison to the Li/MgO catalytic system, it brings considerable improvements in the yields of light olefins (C (2) (=) -C (5) (=) ) at relatively low temperatures indicating synergy from combination of plasma and catalyst. The study on the influence of temperature on the performance of the integrated plasma-Li/MgO system shows dominancy of plasma chemistry at the lower temperature (500A degrees C), while contribution from the catalyst both in hexane activation and in enhancing olefin formation becomes significant at the higher temperature (600A degrees C). At 500A degrees C significant amount of acetylene formation is observed. This is minimized at 600A degrees C at oxygen depleting conditions.
