  • Patent number: 8236185
    Abstract: Toxic substances such as heavy metals are extracted from a medium using a sorbent composition. The sorbent composition is derived by sulfidation of red mud, which contains hydrated ferric oxides derived from the Bayer processing of bauxite ores. Exemplary sulfidizing compounds are H2S, Na2S, K2S, (NH4)2S, and CaSx. The sulfur content typically is from about 0.2 to about 10% above the residual sulfur in the red mud. Sulfidized red mud is an improved sorbent compared to red mud for most of the heavy metals tested (Hg, Cr, Pb, Cu, Zn, Cd, Se, Th, and U). Unlike red mud, sulfidized red mud does not leach naturally contained metals. Sulfidized red mud also prevents leaching of metals when mixed with red mud. Mixtures of sulfidized red mud and red mud are more effective for sorbing other ions, such as As, Co, Mn, and Sr, than sulfidized red mud alone.

  • Patent number: 8227655
    Abstract: The present invention discloses a method for solidifying and stabilizing waste acid including steps of condensing waste acid containing phosphoric acid to reduce the volume; mixing the condensed waste acid with waste acid containing fluoroboric acid to solidify and stabilize the mixed waste acid. The pH of the mixed acid is adjusted by adding barium hydroxide as a neutralizer. The efficiency of solidifying waste acid can be improved by partially granulating and by adding solidifying agent indirectly. The method of the present invention can prevent intensely exothermic reaction caused by adding solidifying agents. Furthermore, the method of the present invention is controlled in a temperature of 30 to 45° C. to improve the polymerization of the mixed waste acid so that the efficiency of solidification thereof can be also improved.

  • Patent number: 8221661
    Abstract: The invention relates to the building material industry and to the use of labor saving tools of industrial continuous and batch brick kilns. Said invention makes it possible to develop a process for producing large-sized clay ceramic products consisting in carrying out rapid and high-quality baking and to accelerate a construction process. The inventive method for producing a clay house or another clay construction consists in forming, during construction, through and blind voids in a wall and a ceiling in such a way that they are closed with a noncombustible material from outside, in covering window and door apertures in the ready clay construction with a noncombustible material, and in baking the construction to a ceramic state in such a way that hot gas penetrates into the voids and that the body of the product is uniformly heated. During baking the construction is used in the form of a furnace (combustion chamber).

  • Patent number: 8218593
    Abstract: Optical devices include a doped glass material in which the dopant facilitates the transmission of energy out from the glass material. The doped glass may not significantly absorb a selected wavelength of laser radiation to be manipulated by the optical devices. The dopant may comprise one or more of a transition metal element, an actinide element, and a lanthanide element. Laser systems include at least one such optical device and a laser device configured to emit a beam to be manipulated by the optical device. Methods for forming optical devices and laser systems including such optical devices include dispersing a dopant within a glass material to form, and forming the glass material into a body having a size and shape configured to manipulate a beam of radiation emitted by a laser device. The dopant is selected to comprise a material that facilitates the transmission of energy out from the glass material.
