Abstract
A self-sustaining system and process for converting organic waste feedstreams into usable solid and gas end products includes a plurality of interconnected retorts, an apparatus for flash pyrolyzing the feedstream to form intermediate gas and solid products, a means for introducing a water spray to refine and cool the intermediate products, a means for separating the gas product from the solid product and a means for regenerating, and thereby further refining, the solid product. In a self-sustaining process, wastes which would otherwise be landfilled are converted to an activated carbon product and a combustible gas mixture of hydrogen, carbon monoxide, and lower hydrocarbons.
Claims5
A process for producing usable gaseous fuel and a carbonaceous an solid from a substantially organic feedstream such as municipal wastes comprising:
- subjecting the feedstream to flash pyrolysis at a temperature of from about 700.degree. to about 2400.degree. F. to form intermediate solid and gas products;
- subjecting the intermediate products to a series of water sprays thereby creating a superheated steam with at least the first of said water sprays and later water sprays cooling and condensing the products, scrubbing and contracting the gases, and forming a slurry with the solid product;
- separating the gas from the slurry;
- scrubbing and drying the gas to remove selected compounds;
- draining the water from the solid in the slurry;
- and
- drying the solid.
A process for producing usable gaseous fuel and carbonaceous solid from a moist and substantially organic feedstream such as municipal wastes comprising:
- subjecting the feedstream to flash pyrolysis at a temperature of from about 700.degree. F. to about 2400.degree. F. to form intermediate products;
- forming a slurry by subjecting the intermediate products to a series of water sprays;
- separating gas from the slurry;
- scrubbing and drying the gas;
- draining the water from the slurry;
- recycling the water drained from the slurry to the water sprays;
- and
- drying the resultant solid.
