Continuous thermal reactor system and method

Patent ·
OSTI ID:5222135
Apparatus and process are disclosed for continuously pyrolyzing or gasifying a particulated 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 system. The pebbles are separated from the pyrolyzed residue comprising an activated char or a residual ash, and are recirculated and reheated in a manner to remove any residual carbonaceous deposits therefrom, whereafter they are reintroduced into the reaction chamber.
