Apparatus is provided for injecting finely divided solid materials into a reaction zone. The apparatus includes a reservoir, selected means for advancing a predetermined particle size of solid materials to the lower portion of the reservoir, metering means for metering predetermined amounts of solid materials selected by the selecting means to gas entrainment means and conduit means to deliver gas entrained solid material into a reaction chamber, the conduit means including a capillary tube having an inside diameter of .030 to .125 inches. A method for injecting finely divided solid materials into a polymerizing reaction chamber for producing polyolefin is also included. |
