  • Publication number: 20130067802
    Abstract: The invention is a bioenergy and/or waste-to-energy process. The invention is a process using controlled pyrolysis reactions to convert biomass and carbon based waste material into carbon byproducts, biofuels and useable energy in the form of heat and/or electricity. The process includes one or more pyrolysis reaction chambers and a thermal oxidizer. Hot, oxygen-free exhaust gases from the thermal oxidizer are modulated through the pyrolysis reaction chambers to sustain the pyrolysis reaction. The exhaust gases along with the pyrolysis gases are drawn from the pyrolysis reaction chambers and routed to the thermal oxidizer. Combustion air is modulated into the thermal oxidizer through one or more ports to control combustion of the pyrolysis gases. After combustion, exhaust gases are recirculated to the pyrolysis reaction chambers to sustain the cycle. The invention proposes a process which is unique in four ways.

  • Patent number: 7749291
    Abstract: The invention relates to a process for the generation of electrical energy and byproducts from the gasification of biomass and/or environmental waste materials. Environmental waste and/or renewable biomass is processed by three separate stages of gasification. The first stage is a pyrolysis chamber with firebox which gasifies solid material into gaseous and liquid hydrocarbon compounds at temperatures below 800 F. The second stage is a fixed bed chamber gasifier which produces the acetylene and hydrogen gases at approximately 1400 F. The third stage is a high temperature reactor which produces molten calcium carbide at 3500 F. Various solid, liquid, and gaseous byproducts are produced along the way. The second stage gases include carbon monoxide, methane, hydrogen, acetylene and other biogases which are used to generate electricity in an internal combustion engine.
