Process for pyrolytic heat recovery enhanced with gasification of organic material

A process for the production of gaseous effluent product rich in hydrogen, carbon monoxide, and other fuel gases as obtained from a feed of heterogeneous organic material comprised of municipal trash, refuse, garbage, or other post-consumer wastes, heavy oils, lube oils, waste hydrocarbons, black liquor, organic solvents, chlorinated solvents, paint, carcinogenic organics, tires, wood, plastics, paper, petroleum residue, coke, charcoal, forest by-products, agricultural waste, medical waste, asphalt, metals, asbestos, batteries, or combinations thereof, which process comprises:

• (A′) subjecting a feed of a heterogeneous organic material in a single reaction chamber under conditions essentially devoid of free oxygen sufficient to gasify said heterogeneous organic material wherein said gasification and pyrolysis occur via an upward countercurrent flow of a wet oxygen-devoid thermal driver gas having sufficient heat and water content to effect anaerobic gasification and pyrolysis contacting directly a downward flowing moving bed of heterogeneous organic material and wherein said driver gas is produced externally to said single reaction chamber, thus:
• (B′) producing effluent fuel gases of having a composition comprising methane, ethane, ethylene, propene, propane, butanes, C4H8, butadienes, pentanes, C5H10, benzene, toluene, xylenes, or combinations thereof;
• and:
• (C′) generating slag, which is in the form of liquid exiting the single reactor chamber and solidifying said slag under ambient conditions for optional subsequent use.
