European foreword
This document (CEN/TR 17103:2017) has been prepared by Technical Committee CEN/TC 19 “Gaseous
and liquid fuels, lubricants and related products of petroleum, synthetic and biological origin”, the
secretariat of which is held by NEN.
Attention is drawn to the possibility that some of the elements of this document may be the subject of
patent rights. CEN shall not be held responsible for identifying any or all such patent rights.
This document has been prepared under a mandate [1] given to CEN by the European Commission and
the European Free Trade Association.
Introduction
The European Union is promoting the use of renewable energy. Liquid biofuels have rarely been used
for CHP applications with the exception of vegetable oils which in some cases have been used in
combined heat and power (CHP) applications and several boiler manufacturers promote its use.
However, given the demand for biodiesel for the transport sector little uptake has been reported for
biodiesel in the CHP sector. Hence the European Commission (EC) requested CEN to develop a
'Technical Specification for a quality specification for pyrolysis oil replacing fuel oils in stationary
internal combustion engines' [1].
Fast pyrolysis bio-oils (FPBO) or fast pyrolysis liquids are completely different from conventional fossil
fuels both in their physical properties and chemical composition. They are brownish liquids with a
distinct and smoky odour. They can be produced from woody biomass [3] and agrobiomass
(herbaceous [3]) and there is a wide range of reactor types suitable for fast pyrolysis bio-oil production.
Contrary to fossil fuels, they are highly polar, mainly water-soluble containing typically about
25 % (m/m) (on wet basis) water, are acidic in nature, dense, and viscous liquids, very poorly or not
miscible with hydrocarbons [4].
CEN adopted work item 00019499 for the requested work and installed CEN/TC 19/WG 41 'Pyrolysis
oil' to develop the CEN Technical Specification. During its work the group encountered the following:
• FPBO is not yet commercialized for stationary internal combustion engines (ICE) and there is
neither enough data on the properties for FPBO for ICE use and parameters to determine
combustion properties are not fully understood. Also the long-duration tests in ICE have not yet
been carried out.
• WG 41 performed an enquiry within the leading engine manufacturers to collect data and proposals
for threshold values. Most of the manufacturers did not have experience with FPBO. Several
comments made by the manufacturers was that further research and development work was
required on several issues (e.g. type of fuel injection system, chemical resistance, effect of
solids/char content of bio-oil on erosion/corrosion at fuel nozzles, and ignition properties).
• There are several important properties (e.g. combustion properties, flash point and chlorine) that
should be incorporated as grade criteria, but no established test methods for fast pyrolysis bio-oil
are available. Research and development is needed to develop these methods to be used for
specification of FPBO for ICE.
WG 41 thus proposed to CEN/TC 19 to draft a Technical Report (TR) instead of a Technical
Specification, which was approved [2] and thereafter adopted by the CEN/BT and accepted by the EC.
This document is laying down the outcome of the study and the quality that so far has been found
acceptable for ICE. Further investigations and market application should be continued in order to
decide to eventually revise this document into a deliverable originally requested by the EC.
1 Scope
This Technical Report describes the key properties of fast pyrolysis bio-oils and their importance to the
fuel quality for use in stationary internal combustion engines.
Internal combustion engine (ICE) in the scope of this document means a type of engine in which heat
energy and mechanical energy is produced inside the engine. ICE include compression ignition engines
(diesel engines) and gas turbines.
Attention is drawn to differences especially in those properties, which can have an effect on the
required engine performance, such as ash, acidity, viscosity, combustion properties, and sulfur content.
In addition to the quality requirements and related test methods for FPBO, further instructions on
storage (Annex A), sampling (Clause 4), and materials compatibility (Annex B) are given.
NOTE For the purposes of this Technical Report, the terms “% (m/m)” and “% (V/V)” are used to represent
the mass fraction (µ) and the volume fraction (φ) of a material, respectively.
