Abstract
The invention provides an improved method and apparatus for feeding solids to a fluidized bed reactor. A back pressure control valve regulates the pressure drop between the pressure above a solids column in a standpipe and the pressure in the reactor. Solids are fed from the standpipe via a conduit without valve means, the conduit contains a bend of an angle greater than the angle of repose of the solids.
