  2. Objective Develop a competitive process for the conversion of Landfill Gas (LFG) into liquid hydrocarbon fuels. Converting waste gas into fuel Storable High energy density Domestic fuel source Carbon offset by use of biomass derived fuels Closed Loop Business Model Our customers are landfill operators High cost involved in fueling their equipment Satisfying federal emissions regulations Dealing with their waste gas Key Understandings Letting nature start the process Feedstock production from bacteria What you put into a landfill is what you get out of a landfill. Every Landfill is different Lower Greenhouse gas production Offset fossil fuel use Stop removal of currently sequestered carbon
  3. Motivation and Process Hypothesis: Conversion of waste Landfill Gases into liquid hydrocarbons is a more feasible system than other proposed technologies. Goals Down scaling of Fischer Tropsch Synthesis Reactor (FTSR) Removing contaminants from LFG Siloxanes, Sulfides, Halides, etc. Modeling a competitive large scale process Lab scale: 0.1 ft3/min (Kinetic data and reactor modeling) Industrial Scale: (Using literature and industry data) Process 2500 ft3/min
  4. The Product
  5. Conclusions Flaring No use for larger installations which could use LFG as a resource Electricity Remains a formidable option due to widespread utilization LFG to CNG Shows promise for modular installment but incurs a high operating cost for the product delivered. LFG to Liquids has the highest rate of return However the technology also incurs a higher risk Return will increase as diesel prices rise and natural gas price falls
