摘要： A vertically oriented plasma reactor is provided. In another aspect, a plasma reactor includes a vertically elongated vacuum chamber, a wall internally projecting within a middle section of the housing, magnets, electrodes and a radio frequency source. A further aspect employs a workpiece-entry port and an opposite workpiece material-exit port, with one located adjacent a top end and the other adjacent a bottom end of a vertically elongated reactor housing or vacuum chamber. Yet another aspect employs a moving or falling-bed plasma reactor for use in activating biochar material.

摘要： A method for regenerating granular activated carbon by arc initiation and discharge includes steps of the granular activated carbon continuously flowing through a heating passage, and applying a DC (direct current) to two electrode plates in the heating passage. Under a combined action of conductive Joule heating and arc heat release, the activated carbon heats up rapidly and an adsorbate is pyrolyzed by high temperature, thereby achieving regeneration. Moreover, a device for regenerating granular activated carbon by arc initiation and discharge includes a feeding device, a heating passage, an aggregate device and an adjustable DC power supply. Two ends of the heating passage are connected with the feeding device and the aggregate device respectively; two electrode plates are provided within the heating passage; the two electrode plates are connected with an output positive pole and an output negative pole of the DC power supply respectively.

摘要： A method of making heteroatom-doped activated carbon is described in this application. Specifically, it describes a process that utilizes liquid furfuryl-functional-group compounds as starting materials, which are then used to dissolve the heteroatom containing source compounds, before being polymerized into solids using catalysts. The polymerized solids are then carbonized and activated to make the heteroatom-doped activated carbon. Electric double-layer capacitors (EDLC) were fabricated with activated carbons doped with boron and nitrogen, and tested for performance. Also, the boron and nitrogen content in the activated carbons was confirmed by chemical analysis.
