Fuel oil composition treatment

摘要

A fuel oil composition such as one containing cracked components is treated to stabilise it against forming sediment and becoming discoloured during storage. The treatment comprises contacting the composition either with one solid polymeric material containing either acidic (eg sulphonic acid) or basic groups (eg substituted guanidines or quaternary ammonium hydroxides) groups, or with more than one such solid polymeric material, the materials being for example resins and being insoluble in the composition.
