| titleOfInvention | A Rapid Determination Method of Diesel Component Variation |
| abstract | The invention relates to the technical field of fuel oil detection, and discloses a rapid determination method for the change of diesel fuel components. Nonane is used as a marker for distinguishing low-boiling components and high-boiling components of diesel fuel, and a gas chromatography simulated distillation method is used to obtain crude oil refining. The content of low-boiling components in diesel before nonane Q1; measure and calculate the changes of the four technical indicators of cetane number, lubricity, kinematic viscosity and closed flash point of diesel samples mixed with gasoline with different concentrations compared with normal diesel; The low-boiling component content Q2 of diesel samples with different concentrations of gasoline, the difference between Q2 and Q1, Q3, and the change values of four technical indicators of diesel samples were modeled, and the correlation formula was fitted; The content of boiling components was substituted into the correlation formula to calculate the change values of the four technical indicators of the diesel under test compared with the normal diesel. The method consumes less sample, the evaluation process is time-consuming, and the cost is low. |
