ALEXANDRIA, Va., Dec. 23 -- United States Patent no. 12,503,660, issued on Dec. 23.
"Supercritical water gasification process" was invented by Thomas J. Baudhuin (Canton, Ga.).
According to the abstract* released by the U.S. Patent & Trademark Office: "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 d...
