technical field
[0001] The invention relates to a method for separating saturated hydrocarbons and aromatic hydrocarbons in light cycle oil. Background technique
[0002] Light cycle oil, usually used as a lower quality blended diesel component, is typically blended with straight run diesel. The annual processing capacity of catalytic cracking units in my country has exceeded 68 million tons, and the annual production capacity of LCO has exceeded 10 million tons. The content of sulfur, nitrogen and aromatics in FCC light cycle oil is relatively high, and the cetane number is low, so it cannot be used as a blending component of clean diesel oil, but can only be used as a blending component of fuel oil. However, the demand for fuel oil is relatively small, and how to use catalytic light cycle oil to get the maximum benefit is a growing problem. At present, the demand for aromatics and olefins in the international market is growing even faster than gasoline and diesel. In th...
