I. Introduction: The Boudouard Process for Synthesis Gas

The Boudouard Reaction1 was discovered in 1905 by French chemist Octave Leopold Boudouard and the water-gas shift reaction2 was discovered by Italian physicist Felice Fontana in 1780.

The Boudouard Reaction is used to gasify coal3,4 with carbon dioxide in order to obtain carbon monoxide and the water-gas shift reaction is used by synthesis gas producers to produce additional hydrogen in order to adjust the hydrogen to carbon monoxide ration in synthesis gas.

The purpose of this discussion is to show recovery of carbon dioxide and water from atmospheric air and to show production of synthesis gas with variable hydrogen to carbon monoxide ratios.

II. Summary

The Boudouard Process is used to make synthesis gas from carbon dioxide and water for applications such as homologation5 to higher molecular weight alcohols and use of the Fischer-Tropsch Reaction6 to make hydrocarbons.

III. The Boudouard Process for synthesis gas

The Boudouard Reaction and the water-gas shift reaction are the basis for the process described in Fig. 1. An ideal application for the process is to make synthesis gas without excessive carbon dioxide emissions and without groundwater consumption.

The Boudouard Process for Synthesis Gas is described below. An ideal application for the process is to make synthesis gas without excessive carbon dioxide emissions and without groundwater consumption as described in Fig.2.

Fig 2. Boudouard Process for Synthesis Gas Datasheet

Boudouard Reaction (datasheet)
  1. Reaction 1 is the standard Boudouard Reaction described by Dr, David G. Walker in US Patent 4,185,083 and his article entitled Coal and Carbon in the Post-Petroleum World and Reaction 2 is the standard water gas shift reaction described in Wikipedia.
  2. Air Extraction devices are the device for removal of carbon dioxide from air developed by Peter Eisenberger7 and Global Thermostat8.
  3. Water extraction can be provided by a atmospheric water generator as described in Wikipedia9. Air10 has a carbon dioxide content of 0.036% and a moisture content of 0-4%.
  4. An ideal application for the Boudouard Process for Synthesis Gas is for producing higher alcohols such as ethanol and butanol from synthesis gas by homolgation. Another application is the production of hydrocarbons by means of the Fischer-Tropsch reaction.

IV. Conclusions:

The Boudouard Process for Synthesis Gas uses air extraction devices to remove carbon dioxide from atmospheric air and atmospheric water generators to remove water from the air. A water gas shift reaction. Is used to convert carbon monoxide to hydrogen and carbon dioxide is recycled in order to make additional carbon monoxide from coal and carbon dioxide.

V. Recommendations:

Utilize atmospheric air to obtain carbon dioxide and water and utilize coal to convert carbon dioxide to carbon monoxide and the carbon monoxide to hydrogen with carbon dioxide recycle in order to eliminate carbon dioxide emissions.
