Production of valuable products with pyrolysis fuel oil (P.F.O) gasification by DC plasma torch

In this research, DC thermal plasma torch is used for pyrolysis fuel oil (PFO) gasification to produce lighter and more valuable gaseous products. The thermal plasma torch is able to generation active medium including energetic species which could crack molecular bonds of heavy hydrocarbons in PFO. The advantage of plasma method over thermal methods is the direct contact of plasma plume, which will reduce the heat loss due to heat transfer without combustion. For this purpose, first plasma torch designed and fabricated. The working state of the torch was optimized regarding power, gas flow rate, distance from nozzle to sample and treatment time. In the optimum point the product hydrogen and gaseous hydrocarbons was studied.
