Abstract: The process described herein converts biomass directly into a combination of hydrogen, methane and carbon dioxide. A portion of the gases are collected at pressures above the thermodynamic critical pressure for water, which is 3200 psi (pounds per square inch). Typical operating pressure at the point where the first portion of gas collected can range from 3200 psi to 6000 psi. Upon cooling, most of the CO2 condenses to a liquid. At this density and pressure, the CO2 can be injected into a deep well aquifer to sequester the carbon dioxide. The overall process is superior to carbon neutral processes, can be carbon negative, and possesses the potential to reverse atmospheric CO2 trends if implemented on a global scale.

Abstract: The present disclosure provides a supercritical fluid gasification system. In some embodiments, the system includes a reactor having a reactor shell including sidewalls that extend between a top reactor cover and a bottom reactor cover, where the sidewalls, the top cover, and the bottom cover enclosing a reactor shell channel. In some embodiments, the reactor includes a thermal shield positioned within the reactor shell channel, the thermal shield having sidewalls that extend between a top thermal shield cover and a bottom thermal shield cover, where the sidewalls, the top thermal shield cover, and the bottom thermal shield cover enclosing a thermal shield channel. In some embodiments, the reactor includes a fluid feed supply conduit in fluid communication with the thermal shield channel, a supercritical fluid conduit in fluid communication with the thermal shield channel, and a product conduit in fluid communication with the thermal shield channel.

Abstract: An apparatus for treating organic waste material characterized by high ash content is disclosed.

Abstract: Non-hazardous organic waste material is introduced into a slagging combustor where it is burned. The burning produces exhaust gases and a slag of molten, inorganic ash which is removed from the combustor. The exhaust gases are treated to cool and dry the gases and to remove a major portion of particulate matter contained therein. A portion of the treated exhaust gases is mixed with a source of concentrated oxygen in a proportion that results in mixed gases having an oxygen concentration of at least 30% by volume. The mixed gases are introduced into the combustor to support the burning of the waste material. Another portion of the treated exhaust gases is further treated to recover the carbon dioxide therefrom.
