"ASTM D86-23 Standard Test Method for Distillation of Petroleum Products and Liquid Fuels at Atmospheric Pressure" provides a standard test procedure for determining the distillation characteristics of petroleum products and liquid fuels at atmospheric pressure. This method is mainly used to evaluate the distillation Linear dispersion of petroleum products such as gasoline, diesel, naphtha, etc., to help determine their volatility, fractionation process and suitability. The distillation process can effectively analyze the composition of petroleum products and their boiling point range, and is a commonly used quality control means in the petroleum and fuel industry. This standard applies to the production, inspection and mass management of liquid fuels to ensure that products meet performance requirements and meet environmental regulations. By implementing this method, the distillation behavior of fuel can be accurately understood, which is of great significance for its process optimization, storage and transportation.
