Xuanzhong Brand activated carbon for desulfurization and denitrification is semicoke activated carbon, which is made from strictly selected top quality coal and blended coal by a series of processes comprising grinding of coals, metering and mixing of coal powder with tar and water, extrusion of the mixed material into cylindrical grains under oil pressure, followed by carbonization, activation and oxidation.

The ZSN has a unique porous structure, better abrasion and pressute resistance, and excellent desulfurizing and denitrifying properties. It is desighed specially for flue gas desulfurizing and swnireidyinf units for coal-fired boilers in thermal power plants, and steel and iron sintering machines in order to cope with acid rains in air pollution
    As is shown in process flow chow chart of desulfurizing and denitrifying unit, activated carbon is moving in fluidizing bed, accompanying adsorption, catalysis, and then desorption with steam and regeneration .So regular shape, fluidity, high abrasion and pressure resistance and good desulfurization and denitrification are essential to this kind of activated carbon. At the very beginning high degree of activation of the carbon is not required and it will be gradually activated during the period of operation and regeneration.
