The Day Cycle
The purpose of this system is to simultaneously produce hydrogen, electricity, oxygen, biofuels/biomass, syngas, and other useful products from waste. The waste feedstocks can be—but are not limited to—municipal solid waste (MSW), sewage, biomass, petroleum byproducts, and medical and toxic wastes. The system is designed to operate without the release of harmful emissions or Green House Gasses, and is based on a unique synergy of proven technologies.
In the first stage the plasma syngas generator is tuned for low nitrogen and carbon monoxide levels while maximizing hydrogen levels. For plasma syngas production there are three general supplies of oxygen or combinations thereof used. The first is pure bottled oxygen in which the carbon in the feedstock is converted into carbon monoxide and the hydrogen contained within the feedstock released. The second option for oxygen is to use atmospheric air in which an elevated nitrogen supply is added to the syngas produced (ambient air is aproximately 80% nitrogen and 20% oxygen,all else being traces). The third supply of oxygen is for steam to be added. Our chosen supply of oxygen is for the ambient air to be removed from the plasma chamber. This will be done thru active carbon and HEPA filters before gasification.. Only steam will be added for any non-feedstock oxygen. During syngas production this will supply the oxygen for carbon monoxide production and add two hydrogen molecules for every oxygen molecule that is added. By minimizing nitrogen in the syngas a water shift reactor (WSR) becomes more efficient, while more hydrogen is produced.
From there the syngas enters a water shift reactor feed steam by a custom-tuned hydrogen power generator. The hydrogen engine will use the high oxygen and low carbon dioxide output from the algae bioreactor as its air supply. This will yield a high steam and low carbon dioxide output for feed to the WSR. By using a water cooling mist or steam cooling on the intake of the engine, we can stay within operating thermal limits for the engine on mainly hydrogen and oxygen and still be reliable. We can do this and avoid the added nitrogen of atmospheric air from entering the combustion process and hence the system. If a higher output temperature is needed for the steam than the engine can supply, one can burn some hydrogen with bioreactor oxygen in the engine exhaust to raise the steam temperature. If one uses catalyst metals less heat energy is required for the chemical reactions, which could help enable one to 'tune' thermal balances and hence the system.
By using syngas production from waste, combined with steam from a hydrogen engine, we can ship out the hydrogen within the syngas and use the engine hydrogen/steam over and over again in a closed loop. This allows hydrogen and electricity production to take place at the same time. This will be done with the base carbon being things we are currently paying to discard and have disappear.
