Background
Agenda 2020



Created in 1994 with the goal to address emissions and energy
consumption within the pulp and paper industry
Redefined itself as a partnership among several government
agencies, the forest products industry, and academia to develop
biofuels technologies
June 2006- AF&PA Released Forest Products Industry
Technology Roadmap


Introduces a new business model based on seven technology
platforms
FT fuels production is a part of the “Advancing the Integrated
Forest Product Biorefinery (IFPB)” platform
Issue Definition
What’s Wrong?





Low efficiency
High pollution
Strict standards
Finite energy source
High dependence on
foreign oil
FT through BLG offers…



Increased efficiency
Reduced emissions
Advanced Properties
Renewable
Homegrown
That was easy you can go home now

FT BTL standardization
Fischer Tropsch Process



Discovered by two German scientists in 1925 in order
to produce liquid fuel from coal feedstock
A process in which a synthesis gas (i.e. syngas)
consisting of hydrogen and carbon monoxide is
reacted with a cobalt catalyst under certain pressures
and temperatures to produce a liquid distillate
The feedstock which is referred to as a syngas can
come from coal, methane or gasified biomass such as
gasified black liquor
Black Liquor Gasification


Black Liquor is a pulping residue left over
after the removal of cellulose and pulping
chemicals for papermaking
Today, Black Liquor is inefficiently burned in
boilers to produce electricity
But if Black Liquor were gasified…

Products
Pulp & Paper Industry
Potential products from a Forest
Biorefinery Model Mill




1.1 million barrels FT liquid fuel
19 million gallons ethanol
6 million gallons of acetic acid
Additional electricity capacity
(Annual Basis)
Benefits
Pulp & Paper

Yearly quantified benefits of IFPB:




$9 million new revenue for pulp and paper
industry
175 million barrels of oil per year in energy
savings
153 million tons of reduced CO2
165,000 new jobs in rural America
Challenges

Partners are needed to minimize financial and
technical risk.

No one has attempted to marry biomass gasifiers
to a gas-to-liquid plant and integrate both units
with a pulp mill
 The project would be large and technically
complicated, relying on multidisciplinary
technological breakthroughs

more efficient and affordable enzymes are needed for
cellulose extraction
Impacts
Diesel Industry
“You are what you eat”
Applies to cars as well
 Vehicle emissions standards (set by E.P.A) must be
supported by the right market fuels
 Advanced emission control systems require advanced
fuels

What this means to an engine
IN
Sulphur
Aromatics
Low Cetane
Lower HV
OUT
PM, NOx traps

CO2
Less Energy
By reducing sulphur and aromatic content you eliminate
the mechanisms to create harmful emissions
Who Cares?
Effect on Original Equipment Manufacturers



Immediate reduction in emissions
without the wait for fleet turn over
Without advanced fuels engine control
strategies are limited
BTL fuels are compatible with current
infrastructure and could be delivered
immediately
Implementation Concerns

Standardization





ASTM D 975
ASTM D 6751
Lubricity
Compatibility of seal materials
A lot of unknowns

Further testing in needed to answer
technical questions
Biomass Energy Policy
R&D Funding

Farm Bill of 2002

Farm Bill of 2007

Energy Policy Act of 2005
Farm Bill 0f 2002


1st Farm Bill to contain an energy title
Renewable Energy and Energy
Efficiency (Sec. 9006)



Established competitive grant programs to
support R&D of biorefineries
Cut then restored
Provides roughly $20 MM/year
Farm Bill of 2007
EPACT 2005

Integrated Biorefinery Demonstration Projects


Biomass Research and Development Act of
2000



Authorized $100 MM FY 07, $125 FY 08
$142 million has been awarded for 62 projects
Also funded through Farm Bill
Regional Biomass Energy Programs


Received NO FY 06 funding
Was not reauthorized in EPACT 2005
Recommendations
Congress
 Make a long term commitment to clean, renewable
alternatives by:
 Reauthorizing the Energy Title of the 2007 Farm Bill
 Continuing to fund Biomass R&D Act of 2000
 Creating of National Bioenergy Trust Fund
 Considering funding the Regional Biomass programs through Fuel
Choices for American Security Act
Recommendations
Agenda 2020
 Create a Committee whose goals would be:
 Lobby Congress
 Most biofuels legislation are directed towards corn ethanol
and biodiesel because they have worked towards recognition
 Work towards ASTM standardization
 New Standard for FT fuels independent of feedstock or as a
biodiesel
 Help organize and prepare applications to federal
grants to obtain funding for projects within the pulp
and paper industry
