“…In this study, transportation fuels in the near-future (5-7 years) were approximated to cost $2-3/gallon gasoline equivalent (gge) for pyrolysis, $4-5/gge for gasification, and $5-6/ gge for cellulosic ethanol through enzymatic hydrolysis [3]. Sandvig et al [162] found fermentation of biooil derived sugars to be economically fascinating when combined into the production of both bio-power and biobased chemicals. These studies attract an increased interest in the production of pyrolytic sugars via fast pyrolysis for generating bio-ethanol.…”

This review highlights the potential of the pyrolysis-based biofuels production, bio-ethanol in particular, and lipid in general as an alternative and sustainable solution for the rising environmental concerns and rapidly depleting natural fuel resources. Levoglucosan (1,6-anhydrous-β-D-glucopyranose) is the major anhydrosugar compound resulting from the degradation of cellulose during the fast pyrolysis process of biomass and thus the most attractive fermentation substrate in the bio-oil. The challenges for pyrolysis-based biorefineries are the inefficient detoxification strategies, and the lack of naturally available efficient and suitable fermentation organisms that could ferment the levoglucosan directly into bio-ethanol. In case of indirect fermentation, acid hydrolysis is used to convert levoglucosan into glucose and subsequently to ethanol and lipids via fermentation biocatalysts, however the presence of fermentation inhibitors poses a big hurdle to successful fermentation relative to pure glucose. Among the detoxification strategies studied so far, over-liming, extraction with solvents like (n-butanol, ethyl acetate), and activated carbon seem very promising, but still further research is required for the optimization of existing detoxification strategies as well as developing new ones. In order to make the pyrolysis-based biofuel production a more efficient as well as cost-effective process, direct fermentation of pyrolysis oil-associated fermentable sugars, especially levoglucosan is highlly desirable. This can be achieved either by expanding the search to identify naturally available direct levoglusoan utilizers or modify the existing fermentation biocatalysts (yeasts and bacteria) with direct levoglucosan pathway coupled with tolerance engineering could significantly improve the overall performance of these microorganisms.

“…The goal of most fast pyrolysis systems is to inject heat into the biomass particle quickly and collect the condensables from the exiting stream quickly and efficiently to maximize liquid yield (Sandvig et al, 2004). The process conditions and desired final product will dictate the selection of an appropriate reaction vessel.…”

“…Bridgwater (1999) stated that as of seven years prior to his study there was no optimal collection method; and that collection requirements may be different between feedstocks and reactor configurations. Common collection methods include electrostatic precipitators, quenching/contact with a cooled liquid (larger scale), shell-in-tube condensers, and fiber filters (Bridgwater, 1999;Sandvig et al, 2004). Soltes and Elder (1981) noted that char yield from softwood pyrolysis is generally higher (than hardwoods), and the yields of acetic acid and methanol (produced after further processing) are higher for softwoods as well.…”

Pyrolysis is a process wherein organic materials are exposed to thermal treatment in the absence of an oxidizing agent, resulting in a solid (char), liquid (tar and bio-oil), and volatile gases (CO, CO 2 , CH 4 , and H 2 ). A low temperature, high heating rate, and short gas residence time will favour bio-oil production. Processing conditions can be altered to produce bio-oil at 65-80% of the original feedstock. Bio-oil can be utilized as a primary or secondary fuel source for boilers, heaters, turbines, engines, etc. However, additional research is required to find solutions to the corrosivity and poor storage characteristics of bio-oil. This paper reviews literature pertinent to bio-oil production via pyrolysis. Also, design considerations and conditions for optimization of bio-oil production are investigated.
