Gasification Method for Reducing Emission of Carbon Dioxide

This invention describes a method to convert carbon-containing materials into useful syngas while reducing carbon dioxide emissions. It works by reacting the material with steam and a catalyst, then taking the resulting syngas and either burning a part of it or separating hydrogen and carbon monoxide from it to create a CO2-rich gas. This CO2-rich gas is then fed back into the initial reaction, and in its most complete form, additional CO2 is separated from the remaining syngas and also recycled.

Why it matters: Filed before the widespread push for green hydrogen and more stringent carbon emission regulations. Advances in catalyst efficiency and gas separation technologies could make this internal CO2 recycling more economically viable now.

Status: ExpiredProtection ended and was never renewed
How hard to build: SpecializedHigh-temperature reactor, catalysts, gas separation, recycling system.
