Definitions
- Jet fuel is currently derived from petroleum resources. Increasing worldwide use of air travel and leveling production of petroleum are likely to result in high prices for jet fuel into the foreseeable future. Unlike other uses for liquid fuels, such as home heating or ground transportation, there are no renewable alternatives available for fueling jet-powered air transportation. For reasons of increased sustainability and national security, it would be desirable to produce jet fuel from renewable resources.
- This invention relates to an integrated suite of processes to make jet fuel from wood.
- the processes are located within a wood products processing facility.
- Fig. 5 is a graph showing accumulation of C3-C7 carboxylic acids in four wood extract fermentation conditions.
- Fig. 6 is a graph showing accumulation of lactic acid in four wood extract fermentation conditions.
- Fig. 7 is a graph showing accumulation of lactic acid in four wood extract fermentation conditions.
- Fig. 8 shows sequencing batch fermentation at 50 gallon scale. After initial batch growth, fermented extract was removed and replaced with fresh extract at a rate of 20% volume once per week. On day 94 the extract was increased to 50% volume once per week.
- Any suitable woody or other lignocellulosic feedstock can be used in the process.
- specific feedstocks of interest include (1) forest residue available as low quality whole tree chips often used for direct combustion in wood-fired boilers and (2) raw wood extracts rich in hemicelluloses that otherwise would have been burned as a part of spent black liquor in recovery boilers at pulp mills. These two feedstocks are potentially available at existing wood processing facilities. Pulp mill facilities can include both producing facilities and repurposed facilities that are no longer producing pulp.
- TDO Thermal deoxygenation
- Hydroprocessing involves hydrogenation and hydroisomerization aimed at producing an appropriate mix of high carbon number alkanes and branched or cyclo alkanes.
- the invention provides an integrated suite of processes to make jet fuel and associated hydrocarbon products from wood.
- the processes are located within a wood products processing facility such as a pulp mill.
- Brownstock which had been produced from wood chips in which much of the hemicellulose had been removed by hot water extraction.
- extract was generated from mixed hardwood either in the Department of Chemical and Biological Engineering at the University of Maine or was kindly supplied by Old Town Fuel and Fiber, of Old Town ME.
- the extracts were used raw, without conditioning.
- the extracts used for this study were prepared by carrying out relatively mild condition extractions on hardwoods using either hot water or water mixed with green liquor.
- Hot water extracts were obtained by cooking aspen wood strands in water.
- the small scale green liquor extract was a blended 1.44% green liquor hemicellulose extract from mixed hard wood chips.
- the total sugar content in the green liquor extract was measured to be around 10.25g/L and the acetic acid content was around 11.8g/L.
- the total sugar content in the hot water extract was measured to be around 27g/L and the acetic acid was about 9.6g/L.
- the large scale green liquor extracts were generated under similar but not identical conditions.
- Inocula for this experiment were obtained from various sources, including secondary clarifier sludge from the waste water treatment facility at a kraft pulp mill, saline sediments from The Great Salt Lake in Utah and salt water sediment collected from tidal flats near Rockland or Friendship, ME. To minimize the exposure to oxygen, these were collected in tightly sealed containers with the solids content having microbes covered with sea water.
- Methanogen Inhibitor
- the small scale experiments were carried out in duplicate or triplicate batch mode to determine reproducibility of results.
- the batch fermentations were performed in 250 ml serum bottles (Wheaton science products # 223950).
- the bottles were filled with approximately 100ml of the wood extract in each bottle, which left sufficient head space for accumulation of produced gasses.
- These bottles were placed in a shaking incubator (Sartorius Certomat BS-1) with continuous shaking at about 200 rpm and constant temperature maintenance. Two different temperatures are investigated for the process: one at 37°C and the other at 55°C.
- the floor scale fermentations took place in a single 50 gallon fermentor.
- One experiment was carried out in sequencing batch mode, in which 20 to 50% of the volume of the fermentor was exchanged once per week with fresh wood extract. This sequencing batch fermentation converted the extract sugar oligomers to organic acids without need of added enzymes or extract conditioning.
- Bench scale scale fermentations were completed at four conditions: hot water extract at 37 and 55°C and green liquor extract at 37 and 55°C. A summary of results is presented in table SUB5.1.
- Floor scale fermentations were carried out at 37 C with calcium carbonate and lime as buffers. In general, higher temperature fermentation favors production of acetic acid whereas mesophilic temperature fermentation produces a broader spectrum of longer chain aliphatic acids.
- Table SUB5.1 Hot water and green liquor extract fermentations at thermophilic and mesophilic temperatures using ammonium bicarbonate as buffering agent.

Abstract
Cette invention concerne une suite intégrée de traitements qui permettent de fabriquer du carburant d'aviation à partir du bois. Dans des modes de réalisation préférés, les traitements sont effectués dans une usine de traitement de produits du bois. L'invention concerne également une plateforme de traitement centrale qui utilise une désoxygénation thermique (TDO) d'acides organiques mélangés afin de produire un mélange majoritairement d'hydrocarbures. L'invention concerne en outre des produits provenant du traitement qui sont hydrotraités afin de faire varier le rendement et la composition du produit d'hydrocarbures qui comprend du carburant d'aviation et d'autres fractions d'hydrocarbures associées. Les produits peuvent être mélangés avec des tri-décanes ou tri-acylglycérides afin d'améliorer la qualité du carburant.
