| Abstract: | High temperature gas chromatographic simulated distillation was applied to rapid determine crude oil distillation,and this method had the advantages of low sample volume and fast,the analysis time was shortened to 18 minutes,and the maximum relative standard deviation was 0.79%.The analysis results obtained by this method were more accurate than that of the true boiling point distillation,and it realized the distribution could be detected under more than 538 ℃ by vacuum distillation to meet the crude oil processing requirement. |
