Abstract: 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.

Abstract: A preparation method of a heat-not-burn cigarette paper with boron nitride as a thermally-conductive filler includes: mixing potassium oleate, polyvinyl alcohol (PVA) and water, thoroughly stirring under an ultrasonic condition, aging, and filtering until there is no precipitate; thoroughly mixing a resulting mixed solution with a softwood pulp and a hardwood pulp to obtain a coarse pulp; and under stirring, adding boron nitride and calcium carbonate as a filler to the coarse pulp, heating to 60° C., and stirring for thorough mixing to obtain a pulp for sizing and papermaking. The present disclosure effectively improves the stability of a cigarette paper by improving a coefficient of thermal conductivity of the paper. Boron nitride, when used as a thermally-conductive filler in a thin-walled or paper product, enables high heat removal capacity. The preparation method retains the original whiteness and transparency of the cigarette paper, and provides high conductivity.
