1 Maizeoline: Biomass to Diesel via Furfural Rebecca Paustian, Stephanie Callahan, Ross Warner, Ryan Felde-Vassallo May 2, 2015

2 What is Biodiesel  Biodiesel is a renewable, clean burning fuel made from plant- based products

3 Importance  6.57 billion barrels of petroleum products consumed in the US in 2013  ~18 million barrels/day  Import ~ 9.3 million barrels/day as of 2014 from 80 different countries  Eventually all known reserves will be depleted

4 Applications and Uses for Biodiesel  Can be used in all diesel engines.  Cleans out engines  Lubricates better then petro-diesel  Was licensed by the California Department of Fish and Game as a shoreline cleaning agent.  Paint and adhesive remover

5 Advantages of Biodiesel  Renewable feedstock  Meets the Clean Air Act Amendments  Comparable energy density and energy content to petro-diesel  Compatible with existing engines  Biodegradable

6 Properties of Biodiesel  Immiscible with water  High flash point  Low vapor pressure

7 Location and Market Opportunities  Plant Location: Spencer, Iowa  Fairly new technology that is being looked by several different companies  Can be blended with petro-diesel  Consumers  US Military  Disneyland  National Parks

10 Biomass to Furfural Furfural Generation Biomass Grinding Furfural Separation Furfural Wastewater Corn Stover Sulfuric acid Ethanol Plant O-nitrotoluene Unused Biomass

11 Furfural Generation  MTC is a novel reactor designed at Delft University of Technology to minimize by-products and improve yield.  Only significant by product is acetic acid  72.7% yield (mass basis)

12 Furfural Separation  NaOH neutralizes the sulfuric acid and generates sodium sulfate ions  O-nitrotoluene is used to remove most of the water in the extraction tower.  Sodium sulfate ions compete with furfural for hydration  improved furfural separation from water  Two vacuum distillation towers isolate furfural from the organic solvent and residual water.

13 Ethanol Production Summary  Recombinant strain of Zymomonas mobilis ferments glucose and pentose sugars into ethanol and CO 2  Recovered as a 99.5% ethanol product  ~150,000 lb/hr is produced
