For reducing the method for total acid value in refinery's raw material |
| abstract |
Describe the method for the total acid value for reducing refinery's raw material.In one embodiment, under the existence of aqueous caustic alkali, make the refinery's raw material comprising naphthenic acid contact with the solid catalyst of significant quantity for some time being enough to the naphthenic acid be neutralized in small part raw material, wherein caustic alkali is sodium hydroxide or potassium hydroxide.Thereafter, by containing aqueous phase therefrom with refinery's raw material in be separated.Use caustic solution pretreatment catalyst in another embodiment and make itself and refinery's contact raw to reduce total acid value. |
