CEN/TC 19/WG 41 - Pyrolysis oil

This European Standard specifies requirements and test methods for fast pyrolysis bio-oils for boiler use at industrial scale (>1 MW thermal capacity), not for domestic use. Two different grades are specified.
It is recommended to draw attention to differences especially in those properties, which can have an effect on the required flue gas treatment system, such as ash, nitrogen, and sulfur content. National and local regulations determine the requirements for flue gas treatment system.
In addition to the quality requirements and test methods for fast pyrolysis bio-oils, further instructions on storage (Annex A), sampling, and materials compatibility (Annex B) are given.
NOTE   For the purposes of this European Standard, the term "% (m/m)" is used to represent respectively the mass fraction.

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.
