| titleOfInvention | Method for separating saturated hydrocarbons and aromatic hydrocarbons from lightweight cycle oil |
| abstract | The invention relates to a method for separating saturated hydrocarbons and aromatic hydrocarbons from lightweight cycle oil to mainly solve a problem of analytic result distortion of the saturated hydrocarbons and the aromatic hydrocarbons in the high-aromatic-hydrocarbon-content lightweight cycle oil in present separation technologies. The method which treats the lightweight cycle oil as an analytic material comprises the following steps: 1, adsorbing the analytic material with an adsorption column of a silica adsorbent I, flushing with an n-pentane solvent I to obtain a solution I, adsorbing through allowing the solution I to enter an adsorption column of an alumina adsorbent II, and flushing with the n-pentane solvent I to obtain a solution II; 2, flushing the adsorption column of the silica adsorbent I with a dichloromethane solvent II to obtain a solution III; 3, flushing the adsorption column II of the alumina adsorbent II with the dichloromethane solvent II to obtain a solution IV; 4, steaming the solution II to remove the n-pentane solvent I, and obtaining the content of the saturated hydrocarbons through a normalization method; and 5, steaming a mixture of the solution III and the solution IV to remove the dichloromethane solvent II, and obtaining the content of the aromatic hydrocarbons through the normalization method. The method well solves the problem through above technical scheme and can be applied to the industrial analysis of the saturated hydrocarbons and the aromatic hydrocarbons in the lightweight cycle oil. |
