GSO ISO 20424:2023 脂肪酸甲酯（FAME） 硫含量的测定 电感耦合等离子体发射光谱（ICP-OES）法

This document specifies a test method for inductively coupled plasma optical emission spectrometry (ICP-OES) for the detection of the sulfur content from 2 mg/kg to 21 mg/kg in fatty acid methyl esters (FAME). NOTE 1 For the purposes of this document, the term "% (m/m)" is used to represent the mass fraction (µ) of the material. NOTE 2 The method can also be used for the determination of concentrations outside the given limits. The precision statement, however, is only valid for the concentration range given in the scope. NOTE 3 The method described in the document was tested with FAME derived from soybean oil and beef tallow. FAME derived from other feedstock, in particular aged oils, may behave different due to the different nature of sulfur compounds.

CAN/CGSB-3.524-2022 BoardBiodiesel (B100) 用于混合中间馏分燃料

This National Standard of Canada applies to one grade of biodiesel that is intended for use as a blending component in middle distillate fuels. Biodiesel meeting this standard is not intended for use as a fuel in its neat form. See Annex B for regulations that apply to diesel fuels. The testing and evaluation of a product against this standard may require the use of materials and/or equipment that could be hazardous. This document does not purport to address all the safety aspects associated with its use. Anyone using this standard has the responsibility to consult the appropriate authorities and to establish appropriate health and safety practices in conjunction with any applicable regulatory requirements prior to its use. Units of measurement – Quantities and dimensions in this standard are provided in met ric units from the International System of Units (SI units). This standard expresses the industry standard nominal measurements in North America of “% by mass” and “% by volume”. The SI equivalent expressions for these units are “% (m/m)” and “% (V/V)” respectively.

GSO ISO/TS 17307:2021 石油产品 生物柴油 气相色谱法测定总酯含量

ISO/TS 17307:2016 establishes a method for determining the total methyl ester content in fatty acid methyl ester (FAME) by gas chromatography and using an external standard. The method is suitable for biodiesel which contains esters between C6 and C26. This method allows verifying that the total ester content is greater than 96,5 % (m/m). NOTE 1 The method also allows determination of the total ethyl ester content in FAEE, but precision for this has not been established. This Technical Specification does not determine the linolenic nor the poly-unsaturated alkyl ester content. Alternative techniques, such as EN 14103[1] and EN 15779[2], respectively, are available for this. NOTE 2 For the purposes of this Technical Specification, the term "% (m/m)" is used to represent the mass fraction, µ.

ISO/TS 17306:2016 establishes a methodology for quantitative determination of free glycerol, mono-, di-, triacylglycerols and total glycerol by gas chromatography in biodiesel produced from any raw material including coconut or palm oil and animal fat. It is not applicable for biodiesel from castor oil. In most actual cases, biodiesel is based on fatty acid methyl esters (FAME). These have also been used during the precision study for this test method. There is no indication that the methodology does not apply to other ester types, but the precision has not been determined nor compared. NOTE For the purposes of this Technical Specification, the term "% (m/m)" is used to represent the mass fraction, µ.

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.
