    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.

    摘要: A process for thermochemical beneficiation of carbonaceous solids including a fraction of particles of a size less than 1/4 inch across is provided. The process includes steps of providing a reactor vessel including therein a retaining structure operably positioned to separate a portion of carbonaceous solids from a wall of the reactor vessel, with a free standing liquids region therebetween. The process includes providing a portion of carbonaceous solids piled above an uppermost liquid level of process liquid within the reactor vessel. The disclosure also provides a preferred reactor arrangement for conduct of the process.

    摘要: The present invention provides a system and method for conducting a coal combustion process, including methods of improving the opacity of the off-gases or inhibiting ash fouling. The method includes a step of combusting pulverized coal to form flyash, including a fume component formed from organically associated inorganics in the pulverized coal, and combustion off-gases, and a step of injecting a substantially noncombustible, preformed, coarse particulate material into the combustion process.
