| titleOfInvention | Method for preparing asphalt resin raw material by using heavy oil of kerosene co-liquefaction product |
| abstract | A method for preparing a pitch resin raw material by using heavy oil of a kerosene co-liquefaction product comprises the steps of separating polar components in the heavy oil by using a first extracting agent to obtain low-polarity component oil, separating non-aromatic components in the low-polarity component oil by using a second extracting agent to obtain an aromatic-rich mixture, and recovering the second extracting agent to obtain residual aromatic-rich component oil, namely a raw material for preparing pitch resin; the invention removes polar components and chain hydrocarbon components in the kerosene co-liquefaction product oil to obtain the aromatic hydrocarbon component with higher purity. The separation method provided by the invention is simple to operate, high in separation efficiency, wide in source of the required extracting agent, good in thermal stability, low in price and low in toxicity, and is suitable for large-scale application. |
