CONTINUOUS THERMAL REACTOR

摘要

CONTINUOUS THERMAL REACTOR Apparatus for continuously pyrolyzing, vaporizing or gasifying a particulate carbonaceous feed material in which preheated heat containing bodies or pebbles are admixed with the feed material in a stratified manner to form a downwardly moving columnar reaction mass, with a remaining portion of the pebbles substantially devoid of any feed material disposed in a surrounding layer relative to the reaction mass. Gas is continuously passed transversely through the reaction mass and surrounding layer in a manner to sweep the gaseous pyrolysis reaction products out of the reaction chamber and wherein the layers of pebbles surrounding the reaction mass serve to effect a deposition of carbonaceous residue preventing encrustation and fouling of the reactor. The pebbles are separated from the pyrolyzed residue comprising an activated char, a residual ash or stripped residue and are recirculated internally of the reactor during which they are reheated in a manner to remove any residual carbonaceous deposits therefrom and thereafter are reintroduced into the reaction chamber.
