  • System and method for processing sewage sludge and other wet organic based feedstocks to generate useful end products
    Patent number: 7322301
    Abstract: A system and method are disclosed for processing sewerage sludge and other organic based feedstocks, in an energy efficient manner that minimizes or eliminates unwanted byproducts, including pathogens, and generates useful environmentally safe products. The sewage sludge or other feedstocks are partially dried before being input to a gasifier operating under partial pyrolytic conditions with a small amount of oxygen or air present to produce fuel in the form of synthesis gas, bio-oil fuel, and char. A small percentage of the fuel may be used to maintain the operation of the feedstock drying process after it is started and a small amount of the synthesis gas produced in the gasifier reacts with the small amount of oxygen present with the feedstock to maintain the pyrolysis temperature in the gasifier in order to make the system economically viable.
