Annotation of standard text ASTM D7544-23 :

This specification details the physical and chemical requirements for pyrolysis liquid biofuels produced from biomass that are intended for use in industrial burners equipped to handle these types of fuels. The type of biofuel covered here is not intended for use in residential heaters, small commercial boilers, engines, or marine applications. It shall remain uniform in medium-term storage and shall not separate into layers due to gravity. Properly sampled test specimens shall undergo test procedures to determine their adherence to the following requirements: gross heat of combustion; water content; pyrolysis solids content; kinematic viscosity; density; sulfur content; ash content; pH; flash point; and pour point.

Keywords:
pyrolysis liquid biofuel, bio-oil, pyrolysis oil, pyoil, py-oil, bio-crude-oil, bio-fuel-oil, wood liquids, burner fuel, renewable energy, alternative energy, fuel oils, furnace oils,, ICS Number Code 75.160.20 (Liquid fuels)

Additional information

1. Scope

1.1?This specification covers grades of pyrolysis liquid biofuel produced from biomass intended for use in various types of fuel-burning equipment under various climatic and operating conditions. These grades are described as follows:

1.1.1?Grade G is intended for use in industrial burners equipped to handle the pyrolysis liquid biofuels meeting the requirements listed for Grade G in Table 1. The pyrolysis liquid biofuel listed under Grade G in Table 1 is not intended for use in residential heaters, small commercial boilers, engines, or marine applications.

1.1.2?Grade D is intended for use in commercial/industrial burners requiring lower solids and ash content and which are equipped to handle the pyrolysis liquid biofuels meeting the requirements listed for Grade D in Table 1. The pyrolysis liquid biofuel listed under Grade D in Table 1 is not intended for use in residential heaters, engines, or marine applications not modified to handle these types of fuels.

Note 1:?For information on the significance of the physical, chemical, and performance properties identified in this specification, see Appendix X1.

1.2?This specification is for use in contracts for the purchase of pyrolysis liquid biofuel and for guidance of consumers of this type of fuel.

1.3?Nothing in this specification should preclude observance of national or local regulations, which may be more restrictive.

Note 2:?The generation and dissipation of static electricity may create problems in the handling of pyrolysis liquid biofuel. For more information on the subject, see Guide D4865.

1.4?The values stated in SI units are to be regarded as standard. No other units of measurement are included in this standard.

1.4.1?ExceptionBTU units are included for information only in 3.2.3.1.

1.5?This standard does not purport to address all of the safety concerns, if any, associated with its use. It is the responsibility of the user of this standard to establish appropriate safety, health, and environmental practices and determine the applicability of regulatory limitations prior to use.

1.6?This international standard was developed in accordance with internationally recognized principles on standardization established in the Decision on Principles for the Development of International Standards, Guides and Recommendations issued by the World Trade Organization Technical Barriers to Trade (TBT) Committee.
