Carbon nano materials such as multi-walled carbon nano tubes (MWCNTs), carbon nano-fibers and graphene were considered to be one of the most important catalyst supports in such a scientific trend [3-7].
Multi-walled Carbon Nano-tubes (MWCNTs) with about 50 nm of outer diameter and 2–5 μm of length were purchased from Chengdu Organic Chenicals Co.Ltd., Chinese Academy of Sciences.

Such thermal methods as combustion, pyrolysis, plasma treatment are the most widely used destruction processes because the treatment of liquid materials and their mixtures occurs with significant reduction of volume and mass [6].
The process efficacy and the transformation depth are affected by the electrolyzer design and anode material.
