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.
