Scope

Scope: This standard specifies the terms and definitions, classification, technical specifications, and testing methods for bio-based oxygenated blending oils used in diesel vehicles. This standard applies to the blending components of diesel fuels for automobiles, tractors, and internal combustion engines, etc. Main technical content: 3.1 Bio-based high-quality oxygenated blending oil: A liquid product obtained after the upgrading of biomass pyrolysis oil, with typical components including molecules containing hydroxyl functional groups and ether functional groups. 3.2 CN40 bio-based oxygenated blending oil: A bio-based oxygenated blending oil with a cetane number of 40-55, primarily suitable for agricultural tractors. 3.3 CN55 bio-based oxygenated blending oil: A bio-based oxygenated blending oil with a cetane number greater than 55, primarily suitable for diesel engine passenger cars. 4. Technical requirements: The technical specifications and testing methods for bio-based oxygenated blending oils used in diesel vehicles are shown in Table 1. Table 1: Technical specifications and testing methods for bio-based oxygenated blending oils used in diesel vehicles Item Quality indicators Testing method CN55 CN40 Cetane number Not less than 55 GB/T 386 Long-chain alcohol ether content (volume fraction) / % Not less than 70 SH/T 0663 Density (20 °C) / (kg/m3) 600-800 GB/T 1337 Kinematic viscosity (40 °C) / (mm2/s) 0.5-6.0 GB/T 265 Flash point (closed cup) / °C Not less than 101 GB/T 261 Cold filter plug point / °C Reported SH/T 0248 Solidification point / °C Not less than -20 GB/T 510 Sulfur content / (mg/kg) Not more than 50 SH/T 0689 Carbon residue (mass fraction) / % Not more than 0.05 GB/T 1714 Sulfate ash (mass fraction) / % Not more than 0.02 GB/T 2433 Solid fine particles (mass fraction) / % Not more than 0.01 ASTM D7579 Water content (mass fraction) / % Not more than 0.1 SH/T 0246
