Integrated Home Energy System (IHES) Concept Description Component Functions/innovations Phased Development Plan Estimated course of events/cost Additional Topics How would we discover the "google in a sheaf" Wrap Up Outline

Slide 4

We propose to manufacture and market a coordinated home vitality framework . Multifeed – Biomass, MSW, Sewage "Clean Gasification" based Multiple vitality transformation alternatives (CHP energy component, Gas Gen, LF) Rationale: Lean (recoveries $), Green (reuse), Mean (independence) Clean Gasification - Enabling Technology for BTLTF Direct rivalry with rough items impossible Additional Discussion Biomass Research database is enormous. How would we discover the "Google in a pile"? Official Summary

World Oil Reserves – "Demonstrated" versus "Problematic" The State of Energy

Slide 10

Market Opportunity The State of Energy

Slide 11

Comparing Fossil & Biomass Fuel Conversion Fossil Fuel: Millions of years worth of green growth (unrefined) & biomass (coal) cooked and dense by the earth Biofuels: Wood, slime, cultivate squander, and so forth that should be dried and changed over Crude Oil (crude) – 42.7 MJ/kg Gasoline - 43.5 MJ/kg (~80%) Diesel - 42.8 MJ/kg (~85%) Biomass/Solids – 6/20 MJ/kg MTG Gasoline - 43.5 MJ/kg (< half) FT Diesel - 42.8 MJ/kg (< 60%) 5 to 15x more info vitality The State of Energy

Slide 12

Liquefaction & Pyrolysis Do not orchestrate transportation review fuel without updating (undeveloped) Pyrolysis oils are item is destructive Biopetrol model is liquefaction of muck to fuel oil/smolder nearby – marketable strategy claims 1yr ROI Dynamotive works with various clients on retrofitted applications (greater/stainless steel pumps, engines and so on) Research Summary

Fischer Tropsch Synthesis Gasification Synthesis Upgrading Research Summary

Slide 14

Fischer Tropsch Synthesis-Chain development an element of temp, weight, impetus sort & condition, reactor plan Exothermic responses prompt to poor temp control and wide appropriations Slurry reactors are ideal however imperfect Microchannel reactors may play yet at the same time new (Velocys) The more unadulterated the syngas the better (notwithstanding for CO2 and N2) Dilute syngas prompts to expansive reactors (higher cost) Research Summary

Slide 15

Methanol Synthesis Research Summary Natural Gas Desulph SMR 2H2 + CO  CH3OH 50 Atm, 270C Copper Oxide Catalyst H = - 92 kJ/mol Gasifier Cleaning Coal or Biomass Steam O2, Air Syngas (H2, CO (CO2, N2)) Compressor Methanol Convertor Cooling/Distillation Methanol Syngas Recycle Loop Purge Gas MTG Process

Slide 16

Methanol Synthesis Methanol Demand 37%  formaldehyde (saps/pastes for molecule load up and employ wood) 21%  MTBE (gas added substance that decreases fumes outflows) 14%  acidic corrosive (chemicals for cements, coatings and materials) Used specifically as a fuel… Burns cleaner than gas (Higher Octane) Corrosive to motor parts, gaskets, and so forth Slower blazing (propel start time) Cold beginning an issue (bring down vapor weight) Absorbs water Research Summary

Slide 17

Methanol to Gasoline Research Summary 2CH 3 OH  CH 3 OCH 3 + H 2 O 320C Alumina CH 3 OCH 3  H 2 O + C 2 – C 5 , alkenes, cycloalkanes, aromatics 400/420C Zeolite Light HC, CO2, H2
