    • A method of treating spent sorbent from power plants containing materials including mercury absorbed from emission gases comprising putting said spent sorbent in an atmosphere isolated container or furnace chamber and heating said sorbent by microwave, radio frequency and/or infrared irradiation. The sorbent is heated to a temperature of at least the boiling point of the major contaminant, including mercury. No air or purge gas is added except to maintain safe pressure conditions, to control combustion of the sorbent and increase efficiency. The resulting vapor is released through an exhaust port of the chamber that leads to a condenser where mercury is condensed and separated. Other residual vapors are led to a scrubber for further cleansing and may be returned to the power plant for other applications. The hot treated sorbent is cooled down prior to contacting with air for later reuse in the power plant.
    • 一种处理来自发电厂的废弃吸附剂的方法,其包含含有从排放气体吸收的汞的材料,包括将所述废弃的吸附剂放置在气体隔离容器或炉室中,并通过微波,射频和/或红外辐射加热所述吸附剂。 将吸附剂加热到至少主要污染物的沸点(包括汞)的温度。 除了保持安全的压力条件,以控制吸附剂的燃烧并提高效率之外,不添加空气或吹扫气体。 所产生的蒸汽通过室的排气口释放,该排气口通向冷凝器,其中汞被冷凝和分离。 其他残余蒸气被引导到洗涤器进行进一步清洁,并且可以将其返回到发电厂以用于其它应用。 热处理的吸附剂在与空气接触之前被冷却,以便在发电厂中再次使用。

    • A method for consolidating powdered material to near net shape and full density is provided. The method includes the steps of: mixing a particulate material with an organic or inorganic binder to form a mold material; shaping the mold material into a mold having a shape and including an external surface and an interior cavity and being of sufficient solidity to maintain its shape yet being compressible under pressure; filling the interior cavity with a powdered material to be consolidated; heating the mold with the powdered material therein to form a heated filled mold; applying pressure to the external surface of the mold sufficient to compress the mold material and transfer a pressurizing force to the powdered material within the mold cavity so as to consolidate the powder and form an article; and removing the article from the mold. In an alternative method, the mold material is made of a particulate material which is held in the shape of the mold by a vacuum.
    • 提供了将粉末状材料固结成近净形状和全密度的方法。 该方法包括以下步骤:将颗粒材料与有机或无机粘合剂混合以形成模具材料; 将模具材料成形为具有外表面和内腔的模具,并具有足够的坚固性以保持其形状,同时在压力下可压缩; 用待固化的粉末材料填充内部空腔; 用其中的粉末材料加热模具以形成加热填充的模具; 向模具的外表面施加足够的压力以压缩模具材料并将加压力转移到模腔内的粉末材料,以便固结粉末并形成制品; 并将物品从模具中取出。 在替代方法中,模具材料由颗粒材料制成,其通过真空保持在模具的形状。
