摘要： A process is provided for handling waste solids produced from the chlorination of titanium-bearing ores in the presence of coke as a reducing agent. The process includes the steps of combining waste metal chloride solids and unreacted ore and coke solids with a liquid whereby waste metal chloride solids are dissolved in the liquid and unreacted ore and coke solids are slurried in the liquid, and separating out the unreacted ore and coke solids from the liquid. The liquid including the dissolved waste metal chlorides is then divided into a recycle substream and a bleed substream. The recycle substream is recycled such that it comprises at least a part of the liquid which is combined with the waste metal chloride solids and unreacted ore and coke solids in the product stream. The bleed substream is neutralized to produce a filterable or directly landfillable mass of waste metal hydroxide solids.

摘要： The present invention provides a method and apparatus for the controlled synthesis of nanoparticles using a high temperature process. The reactor chamber includes a high temperature gas heated by means such as a plasma torch, and a reaction chamber. The homogenizer includes a region between the reactant inlets and the plasma (the spacer zone) to ensure that feeds from the reactant inlets are downstream of the recirculation zone induced by the high temperature gas. It also includes a region downstream of the reactant inlets that provides a nearly I dimensional (varying only in the axial direction) flow and concentration profile in the reaction zone to produce nanoparticles with narrow size distribution.

摘要： A method of continuously producing a non-oxide ceramic formed of a metal constituent and a non-metal constituent. A salt of the metal constituent and a compound of the non-metal constituent and a compound of the non-metal constituent are introduced into a liquid alkali metal or a liquid alkaline earth metal or mixtures to react the constituents substantially submerged in the liquid metal to form ceramic particles. The liquid metal is present in excess of the stoichiometric amount necessary to convert the constituents into ceramic particles to absorb the heat of reaction to maintain the temperature of the ceramic particles below the sintering temperature. Ceramic particles made by the method are part of the invention.

摘要： A method to determine the concentration ratio of carbon monoxide to carbon dioxide in the gaseous product of a fluidized bed reactor for producing titanium tetrachloride. The hot fluidized bed of the reactor is used as the source of infrared radiation which radiation is directed through the gaseous products in upper portion of the reactor through a window in the reactor to an infrared spectrometer. The concentration ratio can be used to control the temperature of the fluidized bed reactor by controlling the amount of cool titanium tetrachloride that is introduced into the reactor.

摘要： An improved process for producing titanium dioxide by reacting a titanium dioxide ore with chlorine to produce a gaseous stream containing titanium tetrachloride, condensing titanium tetrachloride from the gaseous stream containing titanium tetrachloride to produce chlorinator tail gas, vaporizing the condensed titanium tetrachloride, reacting the vaporized titanium tetrachloride with oxygen to produce a gaseous stream containing titanium dioxide particles and chlorine, separating the titanium dioxide particles from the gaseous stream containing titanium dioxide particles and chlorine to produce burner tail gas, analyzing the chlorinator tail gas for residual chlorine to control the step of reacting the titanium dioxide ore with chlorine, analyzing the burner tail gas for oxygen to control the step of reacting the condensed titanium tetrachloride with oxygen. The improvement is to analyze the chlorinator tail gas for residual chlorine (and/or the burner tail gas for oxygen) using an on-line analyzer.
