BioOil
Overview
A
totally different process than that used to produce biodiesel
can be used to convert biomass into a type of fuel similar
to
diesel
known
as BioOil.
The process, called
fast or flash pyrolysis, occurs when
heating compact
solid fuels at temperatures between 350 and 500 degrees Celsius
for a very short period of time (less than 2 seconds). While
there are several fast pyrolysis technologies under development,
there
are only
two commercial fast pyrolysis technologies as of 2006. The BioOils
currently produced are suitable for use in boilers for electricity
generation. Additional research and development is needed to
produce BioOil of sufficient quality for transportation applications.
DynaMotive Energy Systems is commercializing a proprietary fast
pyrolysis process that converts forest and agricultural residue
into liquid BioOil and char. The company launched the first BioOil
cogeneration facility in West Lorn, Ontario, in collaboration
with Erie Flooring and Wood Products Company. The flooring company
provides the wood residue and Dynamotive’s 2.5 megawatt
plant uses its fast pyrolysis technology and a gas turbine
to supply power to the wood product’s mills and lumber
kilns. Dynamotive is now in the process of building a second
200 ton-per-day plant in Western Canada.
Ensyn Group
Inc. has commercialized a fast pyrolysis technology under the
name of Rapid Thermal Processing RTP[tm]. This technology
is based on the biomass refining concept, where value added chemicals
are produced in addition to a consistent quality BioOil. Ensyn
has four RTP[tm] facilities in commercial operation; a new
facility and a BioOil refining plant are currently under
construction. Three of the commercial facilities are in Wisconsin
and one is
in Ottawa, Canada. The largest of these facilities, built in
1996, processes about 75 green tons per day of mixed hardwood
wastes. Ensyn currently produces about 30 chemicals products
from RTP[tm] BioOil with lower value remnant BioOil used for
energy. Ensyn is just beginning to enter the energy market.
