The present disclosure relates to a plasma reactor for plasma-based gas conversion comprising a pin electrode extending along a longitudinal axis from a first end to a second end, an opposing electrode opposing a discharge tip of the 10 pin electrode, a plasma chamber for confining a glow discharge plasma, and an electrically-insulating body that comprises an inner bore extending along the longitudinal axis from a bore entrance to a bore exit. The second end of the pin electrode comprises a discharge tip. The pin electrode penetrates the inner bore from the bore entrance and extends at least partly through the inner bore and a15 radial wall of a portion of the inner bore located between the second end of the pin electrode and the opposing electrode, is radially delimiting the plasma chamber. The plasma reactor is further configured for varying an electrode separation distance between the discharge tip of the pin electrode and the opposing electrode.

The present invention discloses a coal-to-acetylene plasma reactor having coking inhibition and online decoking functions, comprising a vertically arranged cathode rod, an anode and a circulating cooling water jacket arranged outside the anode, the anode includes from top to bottom an anode of the electric arc operation section for cooperating with the cathode rod to generate an electric arc, and an anode of the reaction section located below the electric arc, the anode is grounded, the inner diameter of the anode of the reaction section is 1.2 to 10 times the inner diameter of the anode of the electric arc operation section, and the junction of the anode of the reaction section and the anode of the electric arc operation section is circumferentially provided with a decoking nozzle that can spray a decoking medium toward the anode of the reaction section. The present invention uses the method of changing the inner diameter of the reactor and setting nozzles for diaphragm protection, fundamentally suppressing or even eliminating the coking phenomenon during the operation of the reactor, no need to set the decoking cycle, and realizing the continuous cracking operation of the reactor.
