Abstract

The present invention is an apparatus continuously feeding particulate solids to a TRC reaction chamber or zone at a controlled rate of flow, and for admixing the solids with fluid simultaneously introduced to the reaction zone. This invention utilized one or more conduits, preferably tubular, to transfer the solids from a solids reservoir chamber to the reaction chamber at a controlled rate of flow, the conduits being in open communication with both the reservoir chamber and with the reaction chamber. The conduits are in the nature of orifices, and are symmetrically located across the reactor cross section, said orifices or conduits also being specially oriented with respect to the fluid reactant inlet to promote rapid and intimate mixing of the two phases.
