  5. 6. Process <ul><li>Cascade Process </li></ul><ul><li>Ethanol fermentation: already existing in Brazil </li></ul><ul><li>Biodiesel </li></ul><ul><li>Hydrogen fermentation </li></ul><ul><li>Methane fermentation </li></ul>
  6. 7. Installations involved <ul><li>A reactor of 1m 3 capacity, fully equipped with the control units (heating/temperature control, pH-adjusting, substrate addition, sterilization, pressure control, among others) </li></ul><ul><li>A laboratory to perform the analysis and control the parameters of the process. </li></ul><ul><li>This laboratory shall get the data for the industrial scale fermentation, for the different raw materials available for this process. </li></ul><ul><li>The local and ground facility will be offered by ERGOSTECH </li></ul>
  7. 8. Hydrogen Production Pathway
  8. 9. Microbial strain <ul><li>Patent microbe is owned by Sapporo Breweries </li></ul><ul><li>Exploitation of the patent microbe: subject to agreement of intellectual-property-rights </li></ul><ul><li>Deposited microorganisms: obtained from International Authority Depository (U.S.A. or Germany) </li></ul><ul><li>Some deposited strains present hydrogen productivity near the Sapporo strain </li></ul><ul><li>New strain screening: might be another Joint Research Project </li></ul><ul><li>Although this method requires time, we can obtain the new excellent microbes. </li></ul>
  9. 10. Expected Benefits <ul><li>Optimization of the renewable resources utilization </li></ul><ul><li>Introduce an alternative product to be used as biofuel, using the same agricultural resources </li></ul><ul><li>Increment in the energy recovery of approximate 1.5 times (ca. 50% increase) </li></ul><ul><li>Results in more energy and less waste release </li></ul><ul><li>Alternative process to couple to other biofuel production process, including Biodiesel (oil production) </li></ul>
  11. 12. PILOT PLANT (19×9.8m) Pilot Plant Placement  
  12. 13. 15 m Pilot Plant Layout(not final plan dated 09/05/12)   Sapporo is designing the detail of each equipment’s specification now. These layout, therefore, is possible to be changed according to their specs. If you have any opinions about this plan, please inform us. Refer to your opinions, Sapporo will modify this layout and specs. 19 m 10 m Material Inlet Homogenizer ③ Bioreactor ② Nutrient Treatment & Adjustment Unit N-Source Supplier Raw Material Preparation Tank Cooler ④ Control Panel ⑦ Portable Slurry Pump ⑤ Portable Vessel  400 L ⑥ Portable Vessel  100 L ⑧ Bacteria Propagation Unit 30L ⑨ Bacteria Propagation Unit 200L ⑩ Cooling Water Unit ⑬ Compressor ⑪ Drum Lifter ⑫ Stirer Doorway Movable Installed (Fix) Installed Base ① Raw   Material Treatment & Adjustment Unit Raw Material Supplier sieve Raw Material Preparation Tank WC

  14. 15. Load Concentration <ul><li>Main components of the metabolite of hydrogen fermentation are organic acid </li></ul><ul><li>About 10% of load decreases by hydrogen fermentation </li></ul><ul><li>Organic acid is the most desirable substrate of methane fermentation </li></ul><ul><li>Effluent is used effectively and can maximize the energy recovery from the biomass, if a rapid methane fermentation is coupled to use the organic acid (hydrogen fermentation effluent) </li></ul>
  15. 16. Fermentation Broth <ul><li>The load concentration before and after hydrogen fermentation (acid fermentation) is as follows: </li></ul><ul><ul><li>At raw material concentration is 25 - 30 kg / m 3 </li></ul></ul><ul><ul><li>COD of raw material broth is ca. 33,000 mg / liter </li></ul></ul><ul><ul><li>COD of effluent is ca. 30,000 mg / liter </li></ul></ul>
