Abstract: A process dissolves or disperses asphaltenes from marine fuels by using at least one quaternary ammonium compound. A weight ratio of aromatics to asphaltenes in the marine fuel is not more than 7.0. 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.

Abstract: The present invention is related to a process for obtaining organic ammonium salts (OAS) and their derivatives, supramolecular surfactants (SS), which simultaneously present the properties of traceability and detergents dispersant of organic scales. Organic ammonium salts (OAS) and their derivatives supramolecular surfactants (SS) have applications as differentiators, markers, or tracers in fuels derived from hydrocarbons; and also to disperse organic scales or inhibit the gums precipitation both in injectors and intake valves of automotive vehicle engines. Organic ammonium salts (OAS) are obtained through an acid-base reaction between a molecule from the azo family and an amine. Once the OAS is obtained, it reacts with an organic compound (OC) so that through non-covalent interactions, a self-assembly process occurs that gives rise to the SS. Said process is based on green chemistry, that is, in the absence of solvents. These OAS and SS are quantified through the analytical techniques of ultraviolet-visible (UV-VIS) and high-performance liquid chromatography (HPLC) through a calibration curve. Additionally, its performance as a gum-dispersing agent in a single-cylinder engine is evaluated.

Abstract: The present invention relates to a nitrogen-containing diesel solidification point depressant composition, and preparation and application thereof. The nitrogen-containing diesel solidification point depressant composition includes the following components in percentage by weight: 10-40% of monoisopropanolamine; 10-40% of cyclohexane; 0-20% of polyethylene glycol; and 40-60% of N-tetradecyl methacrylamide-tetradecyl methacrylate. After the prepared diesel solidification point depressant composition is added to commercially available 0 #diesel, a solidification point and a cold filter plugging point of the diesel are respectively depressed by 21-25° C. and 9-13° C.

Abstract: A fuel emulsion for powering a diesel engine contains water, a fuel, and an emulsifier package containing a quaternary ammonium surfactant. A method for powering a diesel engine with the fuel emulsion involves preparing the fuel emulsion by emulsifying a fuel and water in the presence of the emulsifier package. An emulsifier package for emulsifying a fuel and water contains a quaternary ammonium surfactant and at least one nonionic surfactant, which is an alkoxylate. The quaternary ammonium surfactant is obtainable by reacting a quaternizable nitrogen compound containing at least one quaternizable, especially tertiary, amino group with a quaternizing agent, which converts the at least one quaternizable, especially tertiary, amino group to a quaternary ammonium group, where the quaternizing agent is a hydrocarbyl epoxide in combination with a free hydrocarbyl-substituted polycarboxylic acid.
