19、6900:2017 (E) 4 Introduction Fast pyrolysis bio-oils (FPBO) or fast pyrolysis liquids are completely different from petroleum fuels both in their physical properties and chemical composition. They are brownish liquids with a distinct and smoky odour. They can be produced from woody2 biomass and agro

20、biomass (herbaceous2) and there is a wide range of reactor types are 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) of water, acidic in nature, dense, and are viscous liquids, v

21、ery poorly or not miscible with hydrocarbons 3, 6, 18, 19. BS EN 16900:2017EN 16900:2017 (E) 5 1 Scope 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

22、 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 ad

23、dition 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 fracti

32、s and/or agricultural by-products (agricultural residues) SOURCE: modified from FAO unified bioenergy terminology UBET 3.2 fast pyrolysis thermal treatment of lignocellulosic biomass at short hot vapour residence time (typically less than about 5 s) typically at between 450 C 600 C and at near atmos

33、pheric pressure or below, in the absence of oxygen, using small (typically less than 5 mm) dry (typically less than 10 % water) biomass particles Note 1 to entry: Many fast pyrolysis processes are using fluidised or entrained bed reactor with sand as a heat carrier. Note 2 to entry: Under REACH it i

34、s defined as “lignocellulosic biomass, at short hot vapour residence time (typically less than about 10 seconds) typically at between 450-600 C at near atmospheric pressure or below, in the absence of oxygen” 3.3 fast pyrolysis bio-oil FPBO liquid produced by fast pyrolysis from biomass Note 1 to en

35、try: The typical yield of bio-oil is 60 % (m/m) - 75 % (m/m) on wet basis (energy basis) and 55 % (m/m) 65 % (m/m) of organic matter. Other products are char and non-condensable gases. 3.4 solids solid particles which are not soluble in methanol-dichloromethane (1:1), possibly containing inorganic e

36、lements including sand, char, and additional insoluble organic material Note 1 to entry: The solids will in time settle to the bottom or raise up to the surface depending on their density and the fast pyrolysis bio-oil composition. 3.5 stability situation in which physicochemical properties remain u

37、nchanged during handling and storage Note 1 to entry: FPBOs are not chemically or thermally as stable as conventional petroleum fuels due to the high content of reactive oxygen containing compounds and low-boiling volatiles. The instability of FPBOs can be observed via an increase in viscosity (“age

38、ing”) and possible phase-separation by time and temperature. A stability test based on viscosity increase at 80 C in 24 h may be used to predict if the bio-oil will stand for a years storage at room temperature without phase-separation 3. BS EN 16900:2017EN 16900:2017 (E) 7 4 Sampling and sample han

39、dling Samples shall be taken as described in EN ISO 3170:2004 and/or in accordance with the requirements of national standards or regulations for the sampling of fast pyrolysis bio-oil. The national requirements shall be set out in detail or shall be referred as a National Annex to this European Sta

40、ndard. It is strongly advised to review all intended test methods prior to sampling to understand the importance of sampling technique, and special handling requirements. There is some information in EN ISO 3170:2004 that is not relevant with fast pyrolysis bio-oils: fast pyrolysis bio-oil is mostly

41、 water-soluble (approximately 80 %) and hence does not include any free water: sampling methods described in EN ISO 3170:2004, Clause 8 are not relevant for FPBO; for verification of mixing efficiency application of the procedure as described in EN ISO 3170:2004, 9.3.2 is not recommended; water cont

42、ent determination should only be carried out according to ASTM E203. Even though the separation of extractives is very slow, the samples shall be taken immediately after mixing (see Annex A for further instructions). If bio-oil samples are not analysed immediately, samples should be stored in a free

43、zer 3, 4, 5, 14, 15. It is pointed out that the sampling devices, sample bottles, and other devices in contact with bio-oil have to be compatible with bio-oil (see Annex B). Bio-oil shall be well mixed when transferring from the primary sampling process and/or container to another container and/or a

44、nalytical apparatus. Minimum of two samples should be taken and the maximum difference of the viscosity shall not exceed 5 % at 40 C 5. A minimum of 0,1 L sample size is recommended. The bio-oil shall be properly mixed and analysed according to the recommended standard methods. The bio-oil shall not

45、 be filtered or preheated above 40 C for more than 30 min even though mentioned in some of the analysis standards. Fast pyrolysis bio-oils can typically be analysed like single-phase bio-oils because the separation of extractive-rich layer is very slow. However, the sampling and analyses should be c

46、arried out immediately after sample homogenization. 5 Requirements and test methods 5.1 Additives In order to improve the storage stability, the use of additives, like alcohols, is allowed. Suitable fuel additives without known harmful side-effects are recommended in the appropriate amount, to help

47、to avoid aging reactions in the fast pyrolysis bio-oil. 5.2 Generally applicable requirements and related test methods When tested by the methods indicated in Table 1, fast pyrolysis bio-oils shall be in accordance with the limit values specified in the Table 1. The properties listed in the Table 1

48、have been assessed for application in boiler use 6, 7. Precision data from inter-laboratory test programmes are given in Annex C.
