Abstract
A method for removing aromatic compounds from a hydrocarbon fluid comprises contacting the hydrocarbon fluid with a solid-phase polymeric material. The solid-phase polymeric material comprises a cross-linked polymer which contains aromatic groups. The method may be used to prevent the build-up of sludge and soot in a lubricant system in an internal combustion engine. A polymer bead comprising a solid-phase polymeric material is also provided.
