Abstract:

Non-thermal plasma (NTP), also referred to as a cold plasma, is a unique tool with different applications where the temperature of electrons typically ranges from 10000 K to 250000 K while the hot gas exists at room temperature. These highly energetic electrons produce free radicals from parent molecules in multi-step physical and chemical processes, leading to high destructive ability. NTP is currently applied in different applications such as health sectors, environmental remediation, removal of volatile organic pollutants, simultaneous removal of NOx and soot in diesel exhaust and sterilization of air and water. Plasma jets, a category of NTP which can deliver plasma up to a few meters distance, are unique in producing reactive chemistry at room temperature. Therefore, it has attracted much attention in different applications due to their versatility and low-cost operation. Jet plasma has a privilege of lower shock risk, compared with DBD and corona discharge, which can penetrate and propagate inside small holes and flexible dielectric tubes. This is quite useful in different applications. In this sense, we developed a flying jet plasma torch (FJPT) and used it as an impetus in wide spectrum research. Those were dedicated to investigate FJPT as a sole and assisting catalyzing agent for: (1) Biodiesel production from fresh and wasted vegetable oil; (2) Treatment of domestic wastewater; (3) Treatment of raw polymers (polypropylene, polystyrene, and polyethylene) before end use process; (4) Activation of carbon derived from peat soil towards simple way of carbon nano tubes production; (5) Application of jet plasma in health sector (inactivation of wide range pathogens). Recent researches were devoted to utilizing our developed FJPT on: regeneration of reforming spent catalysts, treatment and conversion of land fill leachate towards biofuel production, and production of methanol from wasted steam plasmolysis. So far, a bunch of results of the aforementioned researches were published in refereed journals, while others will be in the near future.
