Process to reduce the pour point of a waxy paraffinic feed-stock |
摘要 |
The invention relates to a process to reduce the pour point of a waxy paraffinic feedstock comprising a fraction boiling above 450° C. by diluting said feedstock with a solvent comprising an aliphatic ketone compound and an aromatic compound, wherein the volume ratio of ketone compound to aromatic compound is lower than 0.7:1, chilling the mixture to a temperature at which wax is caused to precipitate, physically removing the wax from an oil phase and recovering an oil product having a lower pour point than the waxy paraffinic feedstock, wherein at least part of the waxy paraffinic feedstock is derived from Fischer-Tropsch synthesis products. |
