Clean Earth Energy ~fawaii -Milo, LGC Sustainable Integrate~`Waste to Energy ~'a~ties Converting cazbon dioxide to methane would essentially double the amount of hydrogen and liquid synthetic fuel that could be produced at the Hilo, Hawaii landfill. Advanced Chemical Reformer Reactor (ACRR) Scrubbed gas from Phase I operations is provided as feedstock to the Advanced Chemical Reformer Reactor (ACRR). The ACRR facility is an enclosed mechanical plant on a small footprint of approximately 40 ft. x 40 ft. designed to convert landfill gas to clean hydrogen. Reforming occurs in two basic steps. In the first step, water is removed from a hydrated chemical reactant (alkaline metal hydroxide - hydrated), which is pre-heated then combined with pre-heated cazbon beazing gas (methane). Additional reaction heat and pressure is provided in the Advanced Chemical Reformer reactor - a controlled reaction vessel, to form hydrogen gas and alkaline metal vapor. The hydrogen and alkaline metal vapor are separated through cooling and condensation. The liquid alkaline metal is then reclaimed and reformed in a chemical recycling chamber back to alkaline metal hydroxide. This reactant is then recycled again and again through the process as described, to produce hvdroaen eas - in essence an alkaline metal motor. Hydrogen gas from the process is produced at either low pressure or high pressure depending on the need and energy benefit. In the second step, landfill gas containing a mixture containing a portion of clean cazbon dioxide from the landfill and also clean methane from the landfill enters through the ACRR reactor. When these two landfill gases and the alkaline metal hydroxide are mixed at high temperatures as described, they form both carbon monoxide gas, more hydrogen gas, and alkaline metal vapor. The alkaline metal vapor is separated from the other two gases through cooling and condensation and is recycled back to the ACRR reactor. In this manner, the facility also produces synthetic gas composed of carbon monoxide and hydrogen and also relatively pure hydrogen gas. These gases are then further cleaned and separated as required using conventional chemical engineering processes. Hydrogen gas and synthetic gas produced by this means provides five times the capability as provided by methane gas alone. All of the heat fiom the reaction is captured and reused and green house gas emissions are reduced. Both of these gases can be supplied directly to gen sets for the production of long tens stable and low cost electricity. Landfill blocks provide a consistent, continuous and long-term flow of gas, which is cleaned and separated prior to entering the ACRR reactor. Additionally, the ACRR reactor can accept high carbon input sources as feedstock including biomass in all varieties. When spent, after approximately 25 years, the biomass in the landfill blocks contains 80% carbon in the form of inert solids. This material will be emptied from the blocks, shredded, and processed for feeding into the chemical conversion reactor. S/WEF Tec6nicN Proposal ConJidextial 9
