Abstract: This paper tends to give an overview on the principle,the state-of-the-art development of research and applications of chemical conversion processes at ultra-high temperature in the thermal plasma reactors. As an extreme means for process intensification,thermal plasma can provide ultra-high temperature reaction conditions,adjustable oxidative,reductive or inert gas atmosphere,which allows it as a feasible technique to implement clean and highly efficient conversion of low-quality feedstock and hard-to-treat intermediates and wastes. Thermal plasma technique is therefore one of the frontier areas of modern reaction engineering. Meanwhile,the thermal plasma reactions are strongly coupling with the extreme mass/heat transfer processes,which lead to a more complex reaction conditions. Therefore,it is essential to combine the unique characteristics and conversion principles properly to enable a clean,flexible and profitable process. This paper reviews typical thermal plasma processes,involving plasma pyrolysis to produce acetylene,solid waste treatment and nanomaterials synthesis. The potential perspectives of such unique techniques in the applications for the fields of energy,chemicals,environment and materials are discussed.

Key words: thermal plasma, ultra-high temperature, acetylene, solid waste treatment, nano-materials
