Abstract
A process dissolves or disperses asphaltenes from marine fuels by using at least one quaternary ammonium compound. A weight ratio of saturates to asphaltenes in the marine fuel is at least 4.0. A marine fuel is produced that includes saturates, aromatics, and asphaltenes in addition to at least one quaternary ammonium compound. Another process reduces or prevents fouling caused by asphaltenes in a marine fuel.
