摘要：
Various diesel samples with different diesel detergents added were stored at 43°C for 0, 84 and 168 d, respectively, according to ASTM D 4625, and the contents of gum and total insoluble in the diesel samples were measured. Variance analysis was taken to study the factors to affect the contents of gum and total insoluble, and linear regression was conducted to study their relationships with storage time. During long-term storage, contents of gum and total insoluble in diesel samples with detergent were mainly determined by types of diesel and storage time, a little by detergent, and both increased linearly with storage time. The increase rates of gum and total insoluble in diesel samples were mainly determined by types of diesel. There was also a linear relation between gums of diesel with and without detergent. The similar relation was also found between both total insoluble of diesel with and without detergent. The influence of detergent on long-term storage of diesel varied with types of detergent. The changes of contents of gum and total insoluble in diesel sample stored 168 d at 43°C were in the ranges of -8.6% to 40.1% and -37.9% to 76.2%, respectively. The combination of improvement of long-term stability of diesel and selection of detergent with fine performance of reduction total insoluble could inhibit formation of sediment and ensure the diesel with detergent to be stored for a long-term.
