Comment:
Re: Renewable Energy – Inclusion of Torrefied Wood There are many renewable energy technologies that are included in the Topic 5 , Ultralow Carbon Fuels draft outline. One new emerging energy source that is not included is Torrefied Wood. When the overall energy balance of producing a fuel is considered torrefied wood may be one of the most efficient emerging renewable energy fuels and should be included in the outline. Torrefied wood is not new and has been used in Europe and other countries with success in co-firing with coal and as the feedstock in gasification. General information follows: CNFbiofuel, Inc. has developed the following method of liquid immersion torrefaction: Biomass, in the form of wood pellets, is treated in the system and undergoes immersion conduction heating with heat transfer fluid at several different temperature stages. During this process moisture and VOC’s are driven out of the biomass. Further processing results in a change in the biomass structure and chemical composition in an endothermic process. This is torrefaction. All the moisture and volatile organic compound emissions from the heat treatment process are routed through a water cooled condenser and the condensable VOC’s are captured and stored in a vessel for future use. After separation of water from the concentrated VOC liquid it may have commercial value instead of being a pollutant. For example Cedar oil. The torrefied biomass, in the form of enhanced torrefied wood pellets, is a long lasting carbon concentrated pellet that is friable, hydrophobic and resists decay. It should prove to be the ideal feedstock for combination heat and power, clean electric power generation and gasification projects. It can also be the feedstock for conversion to bio-diesel. The finished product at 10,000 Btu/pound or 20 million Btu per ton might also be used as a carbon credit. The CNF process is not-yet-fully-commercialized technology and would benefit from a demonstration at utility scale. Coal fired power plants that are considering co-firing are considered the most likely group to consider a demonstration project to build up sufficient product for test runs. Should the economic, operation and maintenance, and air pollution results prove to be greatly improved, the facility could then consider a commercial size unit. Once fully tested, commercial size processing equipment of 3 to 60 tons per hour may be used for the production of clean electric power, gasification, combination heat and power systems and feedstock for conversion to liquid biofuels. What sets CNFbiofuel™ apart from other prior art Torrefication process systems? CNFbiofuel™ uses a liquid immersion “conduction” process where the biomass is immersed in heat transfer fluid with multiple stages at different temperatures. This puts over 1,000 times as many heat transfer molecules in direct contact with the wood surface as compared to prior art “convection” hot gas methods. These result in smaller equipment, faster processing, greater control, and uniform product, less pollution, less energy use, lower operating costs and recoverable condensed liquids that may have commercial value. Associate Company: Inventive Resources, Inc. was founded by John A. Paoluccio PE in 1984 to bring his patented environmental products and technology to the marketplace. Paoluccio has since acquired 18 US Patents on various products and technologies to help solve global environmental pollution and energy related problems. CNFbiofuel, Inc. was founded in 2010. The USPTO has provided a notice of allowance and a US Patent will be issued. California Registrations: Mechanical Engineer ME15046 Agricultural Engineer AG309 Fire Protection Engineer FP248
