Title: Process for the treatment of sodium-containing heavy residues and fuel so obtained

Abstract: Process for the removal of sodium from sodium-containing heavy fractions from a process for the combined production of styrene and propylene oxide comprising admixing an aqueous solution of an organic carboxylic acid to the heavy fraction at a temperature comprised between C. and C., and separation of the organic phase from the aqueous phase, wherein the organic phase contains less than 0.5% by weight of polymeric solids. The obtained organic phase has low viscosity and ash content and can be used directly as a fuel.
