Introduction[edit]

Based on a personal gasifier (care of Dr. Yuyi Lin [1], Mike Koch, et al.):

which generates gas from any cellulosic biomass:

we can take the process further to make liquid fuels.

Extension to Liquid Fuel Production[edit]

Utilizing Fischer-Tropsch synthesis, a process proven on a large scale:

(from Wikipedia)

our collaboratory will evaluate the possibilities for optimization for small-scale fuel generation. We mean personal fuel makers - a radical proposition. We are writing a grant proposal for this - and will consider a dual license - free to small producers, and royalty-based for companies with gross sales of a million or more dollars.

Student Projects[edit]

Engineering, materials science, and design students are welcome to engage in research on this topic. The questions to be answered are:

  • Optimization of gasifier for controlled feed gas production
  • Integration of gasifier with proven Fischer-Tropsch technology
  • Optimization of efficiency for the above for the small scale (100-1000 gallon per day production

History of Research[edit]

This site is worth researching for an overview of research on Fischer-Tropsch synthesis to date.

Business Planning Due Diligence[edit]

  • Average corn and soybean yields - 140 and 30 bushels per acre - [2]
  • 11 lbs of oil per 60 lb bushel of soybeans - [3]
  • Iowa soybean yields - 40 bushels/acre - [4]
  • Average soybean oil yields per acre - 48 gallons - [5]
    • Wikipedia says 10 gallons in Indiana - [6]
    • This site states 70 gallons - [7]
  • Corn alcohol yield per acre - 230 gallongs - [8]
  • Soybeans require an average of 12.5 gallons of fuel per acre to grow and harvest them - [9]
  • $50/acre switchgrass cost - [10]
  • Average switchgrass yield - 4-6 dry tons (central v. southeast) - [11]
  • Average wood yield - 3 dry tons - [12]
  • Biomass cost = $30/dry ton and $60 for switchgrass and wood - [13]
  • 40% charcoal yield from dry wood - [14]
  • Experiments show 40-50% charcoal yield - [15]
  • 40% charcoal - [16]
  • 20-30% charcoal yield in Missouri kiln - [folk.ntnu.no/lekangso/kurs2005/presentations/Day4-6_Bio-Energy/background/Gronli.pdf]
  • Charcoal contains 30-60% of energy content of original biomass - [folk.ntnu.no/lekangso/kurs2005/presentations/Day4-6_Bio-Energy/background/Gronli.pdf]
  • Max theoretical yield of Fischer Tropsch is 75% - [17]
  • FT uses 200 or 300C temperature processes and 30 bar - [18]
