The research on coking during the pyrolysis of coal to acetylene in the plasma (1) In the arc plasma jet, different kind of coal has different coking character. The aromatics, colloids, asphaltene and Carbenes are the precursors of the cokes.(2) The mostly reasons of coking in the plasma reaction equipment are the particle size, the feeding velocity, the power of plasma and the structure of equipment.
