The knowledge of plasma pyrolysis mechanism is specially introduced. At last, the direction of deeping further research is pointed out.

A set of transparent cold model was designed for studying the movements of biomass particulate in horizontal entrained bed of the plasma heated biomass fast pyrolysis liquefaction prototype.

In the thermal plasma field arc included basic processes and modelling, diagnostics, plasma systems, melting and evaporation, metallurgy, chemical synthesis, and pyrolysis.
