摘要： The present invention relates to a process for recovering chlorine from a feed stream containing metal chlorides using a tubular reactor wherein a hot oxygen containing gas has an initial velocity such that the resulting velocity of the bulk gas formed from mixing the oxygen containing gas with the metal chloride feed stream and a scrubs feed stream is sufficient to remove wall deposits as fast as such deposits are formed.

摘要： The disclosure is directed to a process for producing separable iron and titanium oxides from an ore containing titanium oxide and ferric oxide, comprising: (a) forming agglomerates comprising carbon-based materials and the ore, the quantity of carbon of the agglomerates being sufficient for, at an elevated temperature, reducing ferric oxide to ferrous oxide and forming a ferrous oxide-rich molten slag, (b) introducing the agglomerates onto a carbon bed of a moving hearth furnace; (c) heating the agglomerates in the moving hearth furnace to a temperature sufficient for reducing and melting the agglomerates to produce a ferrous oxide-rich molten slag; (d) metallizing the ferrous oxide of the molten slag by reaction of the ferrous oxide and the carbon of the carbon bed at a furnace temperature sufficient for maintaining the slag in a molten state; and (e) solidifying the slag after metallization of the ferrous oxide to form a matrix of titanium oxide-rich slag having a plurality of metallic iron granules distributed there through; and (f) separating the metallic iron granules from the slag, the slag comprising greater than 85% titanium dioxide based on the entire weight of the matrix after separation of the metallic iron. The disclosure is also directed to a metallization product of a ferrous oxide-rich molten slag.
