Abstract: 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.

Abstract: The present invention provides an adsorbent and a method for desulfurization of gasoline. The adsorbent is obtained by loading active metal component on a composite carrier comprising zeolite and active carbon subjected to alkali treatment respectively, the active metal is selected from one or more elements of IA, IIA, VIII, IB, IIB and VIB groups in the periodic table. This method uses the adsorbent to conduct gasoline adsorption desulfurization, which especially cuts the gasoline into a light and a heavy gasoline fraction firstly, then the light fraction is subjected to adsorption desulfurization using the adsorbent, and the heavy fraction is subjected to selective hydrodesulfurization, a cutting temperature of the light and the heavy gasoline fraction is 70-110° C. The adsorbent has a large sulfur adsorption, a long service life, and simply to be regenerated; the method can realize deep desulfurization of gasoline, and has a less octane number loss.

Abstract: The invention relates to a process for removing mercury from flue gases from combustion plants, wherein the process comprises providing an adsorbent based on carbon, producing an aqueous suspension comprising the adsorbent, introducing the suspension into the flue gas stream from the combustion plants into the dry gas phase of the flue gas which is undersaturated with water vapor and loading the adsorbent with mercury over a predetermined reaction path, keeping the mercury-laden adsorbent out of the flue gas stream and landfilling or regenerating the mercury-laden adsorbent.
