NOVELTY - The pyrolysis/gasification process comprises feeding by loading, conveying, or pneumatic transfer of feedstock comprising solid biomass and carbonaceous environmental waste materials into negative pressure, non-catalyst, non-plasma, non-Fischer-Tropsch pyrolysis reaction chambers (106A), gasifying the feedstock in pyrolysis reaction chambers, where solid materials are thermally carbonized to form solid carbonized products and pyrolysis gases, and removing solid carbonized products from the pyrolysis chambers by dumping, conveying or pneumatic transfer.    USE - The pyrolysis/gasification process is useful for producing solid, liquid and gaseous fuels, carbon products and electricity from biomass and carbonaceous environmental waste materials, where the solid, liquid and gaseous byproducts include methane, ethane, dimethyl ether, acetylene, hydrogen, butanol, alcohols, ethanol, methanol, ethylene, acetone, mineral spirits, activated carbon, charcoal and calcium carbide (all claimed), where the carbonaceous materials include biocrops, animal waste and used tires.    ADVANTAGE - The pyrolysis/gasification process easily and efficiently produces the solid, liquid, gaseous fuels, carbon products and electricity with less environmental pollution.    DETAILED DESCRIPTION - The pyrolysis/gasification process comprises feeding by loading, conveying, or pneumatic transfer of feedstock comprising solid biomass and carbonaceous environmental waste materials into negative pressure, non-catalyst, non-plasma, non-Fischer-Tropsch pyrolysis reaction chambers (106A), gasifying the feedstock in pyrolysis reaction chambers where solid materials are thermally carbonized to form solid carbonized products and pyrolysis gases, and removing solid carbonized products from the pyrolysis chambers by dumping, conveying or pneumatic transfer, delivering an optional portion of the pyrolysis gases from the pyrolysis reaction chambers into a gas-to-liquid condenser by piping and/or ducting, condensing the optional portion of the pyrolysis gases in a condenser into liquid or gaseous biofuels, which are stored, sold or used to fuel or heat other processes, delivering the remaining portion of the pyrolysis gases to a thermal oxidizer (101) by piping/ducting, delivering a controlled amount of combustion air from the atmosphere to the thermal oxidizer by piping/ducting, combusting the remaining portion of the pyrolysis gases with controlled combustion air feed in the thermal oxidizer, venting a portion of the exhaust gases from the thermal oxidizer through a heat exchanger/condenser (102) to atmosphere, delivering, by piping and/or ducting, the remaining portion of the hot, oxygen-free exhaust gases from the thermal oxidizer to the pyrolysis reaction chambers in the pyrolysis phase for supplying energy to sustain the pyrolysis reaction, delivering, by piping and/or ducting, a portion of the hot, oxygen-free exhaust gases from the thermal oxidizer to the pyrolysis reaction chambers in the drying phase for supplying energy to evaporate moisture from the feedstock, delivering, by piping and/or ducting, the oxygen-free gases and evaporated moisture from the pyrolysis reaction chambers in the drying phase to a heat exchanger/condenser so that the oxygen-free gases are cooled and the moisture is condensed and removed, circulating, by piping and/or ducting, the cool, dry, oxygen-free gases from the heat exchanger/condenser though the pyrolysis reaction chambers in the cooling phase and back to the heat exchanger/condenser for cooling the pyrolysis reaction chambers, and exchanging of heat from water vapor stream and vented exhaust stream to preheat the combustion air stream. The process is a self-sustainable process after start-up that utilizes its own internal thermal heat from the combustion reactions to maintain the temperatures in the pyrolysis reaction chambers, thermal oxidizer, and piping/ducting. The pyrolysis reaction is accomplished in oxygen-free conditions with no combustion in the pyrolysis reaction chambers. The rapid cooling is accomplished by circulating oxygen-free gases through the pyrolysis reaction chambers and a heat exchanger. The pyrolysis reactions are accelerated, slowed, or stopped by controlling the heat supply to the pyrolysis reaction chambers. The pyrolysis reaction chambers are mounted on wheel bases for easy transport between loading, process, and unloading stations. A number of pyrolysis reaction chambers is varied to meet production requirements.    DESCRIPTION OF DRAWING(S) - The figure shows a flow cart of a gasification process.
