Pyrolysis Oil from Biomass Could Be Early Alternative to Fossil Oil in Transition to Society Fuelled by Renewables

Pyrolysis of biomass—thermochemical decomposition of wood or organic waste at elevated temperatures and with minimal presence of oxygen—could be an "interesting" option in a transition to replacing today's fossil oil with renewable alternatives, according to a
expert on the thermal conversion of biomass to fuels and chemicals. Thus far, however, lack of knowledge about the composition of the bio-oil obtained from pyrolysis of wood or woody waste has been a hindrance efficiently to design techniques for producing and using such bio-oil, to believe researchers in Bio4Energy at the
SP Energy Technology Center
(SP ETC) at Piteå, in Sweden.
After five years of research in Bio4Energy, and three new funding grants enabling the start of two research projects and the purchase of state-of-the-art instrumentation, that may be about to change.
Until recently, "perhaps 50 per cent of the contents of the oil made by way of pyrolysis could be mapped by ordinary gas chromatography and other methods", said
Swedish Energy Agency
, plus support for highly advanced analytical equipment called GCxGC MS from the
. GC is short for gas chromatography, which in this case is two dimensional, but in this new instrument it has been coupled with a technique called mass spectrometry.
"With the new funding from the Energy Agency for the research projects and for a state-of-the-art analytic instrument from Kempe we are going to complement, strengthen and inventory what is being done on an international top level.
