Raw oil dewaxing method |
| abstract |
The present invention provides a method for dewaxing raw oil, which comprises the following steps: mixing the raw oil and a composite solvent and then performing crystallization and dewaxing treatment to obtain wax crystals and dewaxed oil respectively; and desolvating the wax crystals into a liquid state. treatment to obtain rubber oil; wherein, the composite solvent includes furfural and ketone solvents. The method for dewaxing the raw material oil provided by the invention has higher dewaxing efficiency, can co-produce rubber oil and improve the yield of rubber oil products. |
