Abstract
Described herein are fuel performance additives suitable for renewable diesel, renewable diesel including such additive, methods of improving the demulsiliblity of renewable diesel using fuel performance additives, and the use of a fuel performance additive to improve the demulsiliblity of renewable diesel. The fuel performance additive includes a quaternary ammonium salt and an alkoxylated alkyl phenol formaldehyde resin demulsibility agent.
Claims25
A fuel performance additive composition for fuels including hydrogenated vegetable oil, the fuel performance additive comprising:
- a quaternary ammonium salt obtained from the reaction of a nitrogen containing compound having at least a tertiary amino group and a quaternizing agent;
- a demulsifying agent including an alkoxylated alkyl phenol formaldehyde resin having a weight average molecular weight of at least about 13,000 g/mol, wherein the alkoxylated alkyl phenol formaldehyde resin includes about 20 to about 45 mol percent of ethylene oxide derived moieties, about 55 to about 80 mol percent of propylene oxide derived moieties, and about 0.1 to about 15 mole percent of nonyl phenol derived moieties;
- and
- an organic carrier solvent.
A renewable diesel comprising:
- a major amount of a renewable diesel including hydrogenated vegetable oil and a minor amount of a fuel performance additive;
- a quaternary ammonium salt obtained from the reaction of a nitrogen containing compound having at least a tertiary amino group and a quaternizing agent;
- a demulsifying agent including an alkoxylated alkyl phenol formaldehyde resin having a weight average molecular weight of at least about 13,000 g/mol, wherein the alkoxylated alkyl phenol formaldehyde resin includes about 20 to about 45 mol percent of ethylene oxide derived moieties, about 55 to about 80 mol percent of propylene oxide derived moieties, and about 0.1 to about 15 mol percent of the nonyl phenol derived moieties.
A method of improving the demulsibility of an additive-containing renewable diesel, the method comprising:
- combining a major amount of a renewable diesel including hydrogenated vegetable oil with a fuel performance additive including (i) a quaternary ammonium salt obtained from the reaction of a nitrogen containing compound having at least a tertiary amino group and a quaternizing agent;
- (ii) a demulsifying agent including an alkoxylated alkyl phenol formaldehyde resin having a weight average molecular weight of at least about 13,000 g/mol, wherein the alkoxylated alkyl phenol formaldehyde resin includes about 20 to about 45 mol percent of ethylene oxide derived moieties, about 55 to about 80 mol percent of propylene oxide derived moieties, and about 0.1 to about 15 mol percent of the nonyl phenol derived moieties;
- and (iii) an organic carrier solvent.
