  • Patent number: 10730034
    Abstract: A powdered Iron-Selenide-Oxide sorbent composition, a method of using the sorbent, and a method for producing the sorbent is disclosed for removing mercury vapor from a gaseous stream. The exact ratios of Fe to Se are varied. The method for producing the sorbent comprises the steps of: preparing a base ferrous or ferric oxide (FeOx) media, conditioning the FeOx media with a slurry of ferrous selenite (FeSeO3)/ferrous selenate (FeSeO4), reducing the FeSeO3/FeSeO4 mixture by an elemental iron (Fe0) powder to incorporate selenide into the slurry, and dewatering and oxidizing the slurry. The sorbent can be used alone (or in combination with a powdered activated carbon material or an inert powdered material) by direct injection into the Hg-containing gas stream, by coating of a filter fabric used in bag house with the sorbent, or by using the sorbent in a packed bed gas stream filtration system.

  • Patent number: 10683209
    Abstract: A method for manufacturing polysilicon, according to the present invention, is capable of manufacturing polysilicon with high purity more efficiently in such a manner that a high-temperature and high-speed air stream is formed at the center of a reaction tube, and a high-temperature region may be formed by a vortex formed by the high-temperature and high-speed air stream, so that a raw gas supplied from the side wall of the reaction tube flows by the guiding of the vortex, thereby increasing a stay time and a reaction time of the raw gas within the reaction tube. Furthermore, since the inner wall of the reaction tube is provided with a heat release means, the rapid cooling of a silicon crystal deposited on the inner wall of the reaction tube can induce a columnar crystal in which the silicon crystal is solidified in a direction perpendicular to a crystal face, and it is easy to desorb the silicon crystal produced by rapid heat release via the inner wall of the reaction tube.
