METHOD FOR DEWAXING MINERAL OIL COMPOSITIONS

摘要

The invention relates to a lubricant to be used in a method for reducing the paraffin content in mineral oil compositions. According to the invention, a mineral oil composition is provided with a dewaxing aid, is cooled such that a paraffin deposit is formed, and at least some of the obtained paraffin deposit is removed. A copolymer mixture comprising at least three copolymers is used as a dewaxing aid, said copolymers differing in the composition of the repeat units.
