Pretreatment for Lignocellulosic Bioethanol
Destroy lignin shell protecting cellulose and hemicellulose
Decrease crystallinity of cellulose
Increase porosity
Allows for enzymes or chemicals to have access to substrate (sugar) by removing the recalcitrance of lignocellulose
Cost intensive
Prehydrolysis of some of cellulose
Physical, Chemical, Physicochemical, Biological Methods
Biomass Recalcitrance
Lignocellulosic biomass is often described as “recalcitrant”.
Plant biomass has evolved superb mechanisms for resisting assault on its structural sugars from the microbial and animal kingdoms.
These mechanisms are comprised of both chemical and structural elements: • The waxy barrier and dense cells forming the rind of grasses and bark of
trees. • The vascular structures (tubes) that carefully limit liquid penetration
throughout plant stems. • The composite nature of the plant cell wall that restricts transfer from
cell to cell. • The hemicellulose coating on the cellulose-containing microfibrils if the
cell wall. • The crystalline nature of cellulose itself, and • The inherent difficulty enzymes have acting on insoluble surfaces like
cellulose.

Issues in Pretreatment
Expensive stage in 2nd generation bioethanol
Inhibitors such as:
- Phenolic from lignin degradation
- Furfural from C5 degradation
- HMF(hydroxymethylfurfural) from C6 degradation
Corrosion problems
Acid recovery is expensive
Material loss
Better understanding of plant cell wall structure & function
Hydrolysis (Saccharification)
Polysaccharides break down into monomers follows by fermentation and distillation
Cellulose can be hydrolyzed using:
- Acid hydrolysis (Traditional method)
- Enzymatic hydrolysis (The current state-of-art method)
Acid hydrolysis advantages:
- Faster acting reaction
- Less residence time in reactor
Enzymatic hydrolysis advantages:
- Run at lower temperature
- Higher conversion
- Environmentally friendly
Fermentation
Convert sugars (C5 and/or C6) to ethanol using microbes
Typically Baker’s yeast is used (Saccharomyces cerevisiae).
S. cerevisiae for ethanol from glucose (C6) but not from xylose (C5)
Some bacteria ferment C5 & C6 (E.coli & Z.mobilis) – genetically modified
Conditions: 30°C, pH ~5
Issues in Hydrolysis and Fermentation
Problems for industrial application
- High production cost
- Low yield
Few microorganisms for degrading cellulose
Inhibitors for fermentation
R&D strategies:
- Robust organism to fermenting C5 and C6
- Robust organism toward inhibitors/temperature
Integrate hydrolysis and fermentation into a single microbe
Low conversion rates for C5 sugars
Technology to remove inhibitors is expensive

- Can be regenerated essentially an unlimited number of times by drying
- Pressure swing adsorption (continuous process)
Pervaporation (Evaporation through Membrane)
- Separation of two components by a selective membrane under a pressure gradient in which the component passing the membrane is removed as a gaseous stream (permeate), while the other component remains in the liquid phase and is removed as a more concentrated stream (retentate)
- Development of membrane with a high selectivity and flux
Issues in Purification
Distillation-based Technologies
- High energy cost
- Use of the third component
- High capital cost
- Traditional technologies
Pressure Swing Adsorption
- Recent technology
Pervaporation
- promising in a small scale
- Require development of a new membrane

Bioenergy Production from Various Biomass
History of Biofuels (1)
The oldest form of fuel used in human history: solid biofuels like wood, dung and charcoal
Whale oil for lighting uses (mid 1700s - early 1800s → Ethanol
The first transportation fuels: The first internal combustion engine in the US in 1826 by
Samuel Morey designed to run on a blend of ethanol and turpentine (derived pine trees)
The Ford Model T by Henry Ford in 1908 to run on ethanol
Rudolph Diesel’s engine in 1900 to run on peanut oil
History of Biofuels (2)
Commercial scale production of petroleum (mid 1800s) The Atchison Agrol Co. went
bankrupt in 1939. (2000 biofuel stations
across the Midwest.)
World Word I & II
High demand of ethanol during World War I due to fossil oil
shortages (for synthetic rubber and motor fuel blend)
Several fossil oil crisis since 1970s
1973 oil crisis: caused by the OPEC oil export embargo
1979 oil crisis: caused by the Iranian Revolution
1990 oil price shock: caused by the Gulf War
Agrol 10% ethanol station at a James service station in Lincoln, Nebraska in 1938
Motivation for Biofuels
Large scale production of biofuels (policy-driven)
– Begin since 1970s in US and Brazil: oil crisis
– Significant increase since 2000: declining fossil supplies, high oil prices and climate change
Biofuel production vs. fossil oil price Biofuel production trend

Cellulosic Biofuels Commercialization - Range Fuels
New Zealand-based biofuels start-up LanzaTech purchased a facility in Soperton, Ga.—previously owned by Range Fuels—at auction on Jan. 3 for $5.1 million. Range built the biomass gasification plant with the intention of making ethanol from wood chips, but the firm was unable to make the biofuel. Range’s lender took control of the facility for nonpayment and held the auction to recoup some of a $38 million loan, which had been guaranteed by the Department of Agriculture. Range was also awarded a $43 million grant from the Department of Energy. Range planned to use catalysts to convert the wood-derived gas into ethanol. In contrast, LanzaTech’s process uses proprietary microbes to transform the gas to ethanol. In addition to ethanol, LanzaTech’s microbes produce 2,3-butanediol as a coproduct, Burton reports. Both products can be formulated into jet fuel with help from LanzaTech’s partner firms. The Soperton site, already renamed freedom Pines Biorefinery, will be LanzaTech’s first production facility. The firm is currently working to launch a demonstration facility in Shanghai that will use waste gases from a steel mill operated by China’s Shougang Group to produce biofuels.

EU parliament votes to limit crop-based biofuels
The European Union Parliament has voted to impose a 6 percent limit on the use of biofuels derived from food crops to address competition with food production and to spur the development of renewable fuels made from non-food sources. The vote seeks to avert the EU biofuel requirement of 10 percent for transportation fuels through 2020 based on a directive that dates to 2008. The EU Parliament accounted for indirect land use change (ILUC) factors. A risk exists that biofuel production could spur massive conversion of forest and peatland into land for biofuel crops, which could lead to greater greenhouse-gas emissions.
(Source: Ethanol Producer Magazine, September 11, 2013)
The 6 percent cap is higher than the 5.5 percent cap proposed by the Environment Committee, but lower than the 8 percent lobbied for by the biofuels industry. The Parliament also proposed a 2.5 percent target for second generation biofuels or fuels derived from non-food sources like farm and industry waste. A 7.5 percent limit on ethanol in gasoline blends was also approved.
Poet, Royal DSM Create Joint Venture to Make Cellulosic Ethanol Poet LLC, the largest U.S. corn- based ethanol producer by installed capacity, established a joint venture with Royal DSM NV (DSM) to produce cellulosic ethanol and license the technology to other plants in the U.S. and globally. The companies will each own 50 percent of the joint venture, named Poet-DSM Advanced Biofuels LLC, Poet said today in a statement. The venture will let Poet build one of the first cellulosic ethanol plants in the U.S. and decline a $105 million U.S. loan guarantee. Initial capital expenditure by the venture will be $250 million, which will be invested in Poet’s Project Liberty facility in Emmetsburg, Iowa.
The Emmetsburg plant is expected to begin production in the second half of 2013 and will convert corn cobs and other crop residue into 25 million gallons of ethanol a year. The venture intends to deploy the technology at Poet’s 26 other U.S. corn ethanol plants and license the technology to other producers globally. As much as 1 billion gallons of cellulosic ethanol could be produced annually at Poet’s 27 plants if the technology is deployed at all of them, according to the statement.

Cellulosic Biofuels Commercialization – POET
POET-DSM’s first commercial cellulosic bioethanol
POET-DSM Advanced Biofuel’s first commercial cellulosic bio-ethanol plant remains on schedule for startup in the first part of 2014 as workers continue equipment installation and other activity through the winter. The plant, dubbed “Project LIBERTY,” will produce 20 million gallons of cellulosic biofuel per year—later ramping up to 25 million gallons—from corn cobs, leaves, husk and some stalk. Farmers primarily in a 40-mile radius to the plant harvested approximately 100,000 tons of biomass this fall to be used to start the plant and operate it through next fall. Farmers are already signing contracts for the 2014 harvest. Additionally, POET-DSM is in talks with other ethanol producers about expanding this technology to more plants around the US in the future. Royal DSM and POET, LLC, one of the world’s largest ethanol producers, formed a joint venture in January 2012 to demonstrate and license commercial cellulosic bioethanol production based on their proprietary and complementary technologies.

Mercedes trials agricultural waste-based fuel
Mercedes is to run a pilot project to trial the use of second-generation biofuel. Working in partnership with Clariant and Haltermann, the carmaker will trial the use of a fuel called sunliquid20, a super grade fuel consisting of 20 per cent cellulosic ethanol, produced from agricultural waste such as straw. Over the next twelve months, vehicles from a Mercedes-Benz test fleet consisting of a number of model types, will be run on the new fuel, refilling at an internal petrol station installed especially at for the project at the firm’s Stuttgart-Untertürkheim site. With an octane rating (RON) of more than 100, the fuel guarantees a high level of efficiency.
The cellulosic ethanol comes from Clariant's sunliquid demonstration plant in Straubing, where approximately 4,500 tonnes of agricultural residues such as grain straw or corn stover are converted into cellulosic ethanol each year. At the Haltermann plant in Hamburg the bioethanol is mixed with selected components to form the fuel; the specifications of which reflect potential European E20 fuel quality.

China approves aviation biofuel
Government officials in China have approved a biobased aviation fuel for commercial use, with the Civil Aviation Administration of China (CAAC) awarding Sinopec the first certificate of airworthiness for biobased jet fuel.
According to CAAC officials, the biojet fuel complies with the CTSO-2C701 standard that applies to civil aviation jet fuel containing synthesized hydrocarbons. CTSO-2C701 requires alternative fuel and its synthetic paraffinic kerosene (SPK) component to conform to ASTM D7566-11a, a specification for aviation fuel containing synthesized hydrocarbons, and the supplement in CTSO-2C701.
(Source: Avionics-Intelligence, February 21, 2014)
In April 2013, Sinopec achieved the first test flight powered by its aviation biofuel: an Airbus A320 owned and operated by China Eastern Airlines completed an 85-minute flight on biojet fuel made from palm oil and recycled cooking oil feedstocks.

US Military drop-in biofuels development
The U.S. biofuels industry was able to maintain support from the more-than-willing U.S. military. The Department of Energy (DOE) granted $18 million to four biorefineries to develop pilot-scale drop-in biofuels projects to meet military specifications for jet fuel and ship diesel. The military has shown eager support for the biofuels industry through past purchases of drop-in biofuels for demonstration and testing purposes. In December 2011, the Navy purchased 450,000 gallons of cooking oil- and algae-based drop-in fuels for the jets and vessels to be displayed in the Great Green Fleet during the summer 2012 Rim of RIMPAC in Hawaii. The biofuels were mixed in a 50/50 blend with traditional fossil fuels, which amounted to about $15 per gallon.
The biorefineries were Frontline Bioenergy LLCM (up to $4.2 million; Ames, Iowa), Cobalt Technologies (up to $2.5 million; Mountain View, California), Mercurius Biorefining, Inc. (up to $4.6 million; Ferndale, Washington), BioProcess Algae (up to $6.4 million; Shenandoah, Iowa)

Seaweed could be new next biofuel
The University of Greenwich is a key player in a consortium of 12 UK universities and companies to develop manufacturing processes that can remove the high water content, and preserve seaweed for year-round use.
There is a global race on to develop the technologies to make seaweed a viable source of green power. Salt-water algae are a very attractive proposition as an alternative biofuel if the challenges can be overcome.
The consortium, known as MacroBioCrude, received EPSRC funding to establish an integrated supply and processing pipeline for the sustainable manufacture of liquid hydrocarbon fuels from seaweed. MacroBioCrude brings together researchers from six universities: Greenwich, Durham, Aberystwyth, Swansea, Harper Adams, and Highlands and Islands, as well as industrial partners Johnson Matthey Catalysts, Johnson Matthey Davy Technologies, Silage Solutions Ltd, Shell, and the Centre for Process Innovation (CPI).
Ensilage – a method traditionally used by farmers to turn grass into hay for winter animal feed – has potential to stop the seaweed rotting. The research, backed by £1.6m from the Engineering and Physical Sciences Research Council, will also explore the conversion of wet seaweed to gas, which can in turn be converted to liquid fuel.
