M/525 - Standards on pyrolysis oils

This document specifies the quality for marketed and delivered stationary engine fuel derived from fast pyrolysis oil processes. It is applicable to fast pyrolysis oils for use in stationary internal combustion engines and related power generating equipment. It is intended as an alternative to or blending component in fuel oil for stationary applications.

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.

This European Standard specifies requirements and test methods for marketed and delivered fuel derived from fast pyrolysis oil processes. It is applicable to fast pyrolysis oils for use in industrial boilers and related heat or electricity producing equipment. It is intended as an alternative to or blending component in heavy or light fuel oil used for similar purposes.

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.
