Method and apparatus for reduction of metal oxides |
摘要 |
A method of reducing metal oxides comprises introducing feedstock material into a plasma torch reactor according to two different flow patterns. A primary feedstock is fed into the immediate vicinity of the plasma stream in a helical pattern surrounding the plasma stream. The primary feedstock material preferably comprises the metal oxides to be reduced within the reactor. A secondary feedstock material is fed at a more remote location, preferably in a flow pattern developing a protective wall for the inside of the reactor. A preferred assembly is provided for application of the process. For the preferred embodiment, the assembly comprises a top plate, a central ramp, a bottom plate and a liner to form separate feed channels for the primary and secondary feedstock.
