A rapid method for analyzing the group compositions of delayed coking feedstock oil by rod-shaped thin-layer chromatography with flame ionization detector(TLC/FID)is in-vestigated.The sample is separated into four group-components(saturated hydrocarbons,aro-matics hydrocarbons,glial substances,and asphaltenes)by using three different polar develo-ping agent with rod-shaped thin-layer chromatographic column.The precision of this method is evaluated through repeated experiments,and relative standard deviation of the four compo-nents is less than 3％,extreme difference values are all less than 3.5％.
