[Terrapreta] 200 tons per day Dynamotive plant in Missouri

[Sean K. Barry]

Hi Gerrit,

Well that's impressive.  I did not think "fast-pyrolysis" was capable of such a high yield in charcoal.  My reading on this has lead me to believe that it produced large gas and liquid fractions, but little or no charcoal.  Apparently that is wrong?

Regards,

SKB

  Here at Dynamotive's plant in West Lorne, they get about 18% yield of char.

    Hi Erich,

    I don't know for sure, but I doubt that the same fast pyrolysis reaction produces 34,000 gallons of bio-oil AND 15% yield (~30 tons) of charcoal from 200 ton of biomass per day.  It would be worth asking Dynamotive what the charcoal yield is.

      "200 tons per day of wood by-products and residues from nearby sawmills into 34,000 gallons per day of bio-oil "

      I'm guessing the char would be about 30 tons / day?

      In Argentina, $50 million for 15.7 Megawatt Plant, a bit costly per Megawatt;

      "Each complex will be comprised of a 15.7 megawatt electricity generating station powered by the majority of the fuel output of two 200-ton-per-day modular plants producing bio-oil from wood waste and residues from nearby forests and other biomass residue. Excess bio-oil produced at these facilities will be sold into commercial and industrial fuel markets"
