The Syntec Process focuses on an entirely
different ethanol production methodology from today’s
conventional method that relies on the fermentation of food
chain feedstocks (i.e. corn or sugar cane). Syntec uses
source feedstocks from renewable waste materials including
wood waste, crop residues including sugar cane bagasse and
corn stover, organic waste, manure, sewage digester gas or
landfill gas.
Technically speaking, the Syntec Process is a BTL
(biomass-to-liquid) conversion path quite similar to modern
day methanol or GTL (gas-to-liquid) production processes
used commercially. The key differentiating factors are the
feedstocks, catalysts and operating parameters.
There are 3 basic steps in the Syntec Process:
i. production of syngas (CO, H2) either
through the gasification of biomass feedstock, or through
steam reforming/partial oxidation of biogas or landfill gas,
ii. conversion of syngas to bio-alcohols over Syntec
catalyst in a fixed bed reaction unit,
iii. separation and purification of bio-alcohols (high
purity) to ethanol, methanol, n-propanol and n-butanol. |
The Syntec Process has the potential to
revolutionize the ethanol industry with higher ethanol
yields and lower production costs per ton of feedstock than
any other ethanol production path in use today. Furthermore,
it is anticipated that the Syntec Process will enable the
conventional ethanol industry to value add by using these
well established chemical processes (via the DOE’s
integrated biorefinery program) to obtain production and
efficiency metrics beyond which traditional grain based
fermentation processes can offer.
Perhaps the most important aspect of the Syntec Process is
the ability to convert abundant, low cost (sometimes
negative cost) waste products into ethanol and bio-alcohols
without harming the agricultural land base or competing with
consumable food stocks. These green biofuels significantly
reduce green house gas emission. Moreover, enough biomass
exists and is renewed every year in North America, and other
parts of the world, to significantly reduce a country’s
dependence on imported oil required for petroleum derived
fuels.
