Syngas, or synthesis gas, is a fuel gas mixture consisting primarily of hydrogen, carbon monoxide, and very often some carbon dioxide and other impurities.

Syngas from biomass and other renewable sources contains signficant amounts of impurities which must be removed before feeding bio-fermentation reactors or catalysts.

Koa Energy licenses two patents which are critical to good environmental, operational and financial performance of converting biomass to usable fuels, chemicals or materials.

US PATENT NO 7919070 : Multizone Reforming Methods and Apparatus for Conversion of Devolatilized Biomass to Syngas.

US PATENT NO 8026290: Methods and Apparatus for Continuous Removal of Carbon Dioxide from a Mixture of Reacting Gases
