“…ASTM #2 fuel oil is also considered a volatile fuel as the specifications are not as strict as for #1 fuel oil. In addition, applications using ASTM #2 fuel oil generally have some preheating, which would likely also be required for an IEA #2 fuel oil [77].…”

“…The two oils using cyclones only generally met the proposed IEA specifications for #6 heavy bio-oil; they failed to meet only the flash point, LHV, and filtered solid specs [77]. The upgraded bio-oil (i.e., via hot gas filtration) met the flash point and filtered solid specifications for the IEA #6 heavy bio-oil oil and almost achieved the LHV.…”

“…The committee does not believe that pyrolysis oils will be able to meet the viscosity, volatility and residue specifications for #1 fuel oil and so they did not develop specifications for these oils [77]. ASTM #2 fuel oil is also considered a volatile fuel as the specifications are not as strict as for #1 fuel oil.…”

“…Three example bio-oils were highlighted in the Diebold [77] report; one that had been upgraded with hot gas filtration and two that had only cyclones. The two oils using cyclones only generally met the proposed IEA specifications for #6 heavy bio-oil; they failed to meet only the flash point, LHV, and filtered solid specs [77].…”

“…In 1996 the Pyrolysis Activity of the International Energy Agreement under Task XIII proposed a series of specifications for bio-oil [51] that were modeled after the ASTM specifications for hydrocarbon fuels. The proposed specifications attempted to mimic as much as possible the key 25 properties established for petroleum fuels that have major design considerations for end use devices.…”

Executive SummaryPyrolysis is one of a number of possible paths for converting biomass to higher value products. As such, this technology can play a role in a biorefinery model to expand the suite of product options available from biomass. The intent of this report is to provide the reader with a broad perspective of pyrolysis technology as it relates to converting biomass substrates to a liquid "bio oil" product, and a detailed technical and economic assessment of a fast pyrolysis plant producing 16 tonne/day of bio-oil.The international research community has developed a considerable body of knowledge on the topic over the last twenty-five years. The first part of this report attempts to synthesize much of this information into the relevant issues that are important to advancing pyrolysis technology to commercialization. The most relevant topics fall under the following categories: 1) Technical requirements for converting biomass to high yields of liquid bio-oil 2) Reactor designs capable of meeting technical requirements 3) Bio-oil stability issues and recent findings that address the problem 4) Product specifications and standards that need to be established 5) Applications for using bio-oil in existing or modified end use devices 6) Environmental, safety, and health issues For the bio-oil plant technical and economic analysis, the process is based on fast pyrolysis, which is composed of five major processing areas: feed handling and drying, pyrolysis, char combustion, product recovery, and steam generation. An ASPEN model was developed to simulate the operation of the bio-oil production plant. Based on a 550 tonne/day biomass (wood chips, 50% by mass water content) feed, the cost of the bio-oil for a fully equity financed plant and 10% internal rate of return is $7.62/GJ on a lower heating value (LHV) basis.
