Study on Reaction Mechanism during the Pyrolysis of Coal to Acetylene in the Plasma

Abstract:

The pyrolysis of coal to acetylene is studied with Pingshuo coal, Zichang coal and Dongshan coal in the plasma, and its course is analysised by coal chemical groups. The reaction mechanism of imitate free radicals is proposed in the pyrolysis of coal to acetylene in the plasma, the free radicals formation of high-temperature plasma and the composite dynamics are discussed. The results can educe that the acetylene content is higher of the organic product in the high temperature center zone of the pyrolysis of coal to acetylene in the plasma which base on the discussion of the saturates free radicals generating and compounding, combine with the reaction of aromatics, colloids and asphaltene and carbenes. It also can indicate that free radical reaction mechanism is applicable and feasible to explain coal of high-temperature centre zone in the plasma reaction.
