Abstract

Biomass is a key element in biofuels which can be defined as a fuel produced through contemporary biological processes, and its increased use can support the EU's aims of reducing greenhouse gas emissions. Information on the nature and the quality of the biomass or biofuel is important in order to support the optimization of their combustion with respect to realizing higher efficiencies and lower emissions during energy production. Three reference materials were produced by a collaborative approach among national metrology institutes and designated institutes within the scope of the EMPIR project: BIOFMET. The project was aimed to establish advanced traceable measurement standards for the determination of the calorific value, impurities, and other parameters such as density, kinematic viscosity, moisture, and ash. This paper presents the sampling and processing methodology, homogeneity, stability, characterization campaign, the assignment of property values, and their associated uncertainties in compliance with ISO 17034 for biofuel reference materials: biodiesel, wood pellet powder, and wood pellet. Parameters of interest in biodiesel reference material-UME BIOFMET CRM 01 are gross calorific value (GCV), density, viscosity, and mass fractions of Ca, K, Mg, Na, P, and S elements. Parameters to be certified in wood pellet powder reference material-UME BIOFMET CRM 02 are GCV, moisture, ash, and mass fractions of Al, Cr, K, Mg, Mn, Ni, S, and Zn elements. Parameters to be certified in the wood pellet reference material-UME BIOFMET CRM 03 are GCV and moisture. The homogeneity and stability of the materials were assessed in accordance with ISO 33405. The materials were characterized by interlaboratory comparison studies among competent metrology institute and designated institute laboratories. Assigned values and uncertainties of the certified values were calculated in accordance with ISO 33405, and uncertainties include characterization, homogeneity, and stability components. The developed CRMs are intended to be used for the development and validation of measurement procedures for the determination and quality control/assurance purposes of the quality parameters for biofuels. It should be emphasized that the UME BIOFMET CRM 01-Biodiesel CRM is the first biodiesel reference material certified for calorific value. Among the developed wood CRMs, the pellet form, UME BIOFMET CRM 03, was found to be more stable than the powder one, UME BIOFMET CRM 02, for the moisture parameter. Sixfold lower relative uncertainty value for short-term stability at 45 °C and twofold lower relative uncertainty value for long-term stability at 22 °C were obtained for the moisture parameter of the CRM in pellet form compared to the CRM in powder form.

通过联合研究项目开发生物柴油和木屑颗粒质量参数的三种生物燃料标准。
生物质是生物燃料的关键元素,生物燃料可以定义为通过当代生物过程生产的燃料,其使用的增加可以支持欧盟减少温室气体排放的目标。关于生物质或生物燃料的性质和质量的信息非常重要,以便支持其燃烧的优化,从而在能源生产过程中实现更高的效率和更低的排放。在EMPIR项目范围内,国家计量研究所和指定研究所之间的合作方法制作了三份参考材料:BIOFMET。该项目旨在建立先进的可追溯测量标准,以确定热值、杂质和其他参数,如密度、运动粘度、水分和灰分。本文介绍了生物燃料参考材料(生物柴油、木屑颗粒粉末和木屑颗粒)的采样和处理方法、均匀性、稳定性、表征活动、属性值的分配及其相关的不确定度,符合ISO 17034。生物柴油标准物质ume BIOFMET CRM 01的相关参数包括Ca、K、Mg、Na、P和S元素的总热值(GCV)、密度、粘度和质量分数。在木屑颗粒粉末参考材料- ume BIOFMET CRM 02中认证的参数是GCV,水分,灰分和Al, Cr, K, Mg, Mn, Ni, S和Zn元素的质量分数。木屑颗粒参考材料ume BIOFMET CRM 03中需要认证的参数是GCV和湿度。材料的均匀性和稳定性按照ISO 33405进行评估。在主管计量机构和指定机构实验室之间进行了实验室间的比较研究。根据ISO 33405计算认证值的赋值和不确定度,不确定度包括表征、均匀性和稳定性成分。开发的crm旨在用于开发和验证测量程序,以确定和质量控制/保证生物燃料的质量参数。应该强调的是,UME BIOFMET CRM 01-Biodiesel CRM是第一个通过热值认证的生物柴油参考物质。在开发的木质CRM中,颗粒状的UME BIOFMET CRM 03比粉末状的UME BIOFMET CRM 02在水分参数上更稳定。与粉末形式的CRM相比,颗粒形式的CRM的水分参数在45°C下的短期稳定性相对不确定值降低了6倍,在22°C下的长期稳定性相对不确定值降低了2倍。
