ABSTRACT:
Methods for recovery of concentrates of lubricating compounds from vegetable and animal oils, fats and greases that allow separation of triglycerides, from components with higher lubricity or enrichment protocols that increase the concentration of high lubricity compounds in the triglyceride. The triglycerides are transesterified with a lower alcohol to produce alkyl esters. Following the conversion process the esters are separated from high molecular weight high lubricity compounds by distillation. The esters have some lubricity and may be sold as pollution reducing fuel components. The high boiling point compounds that are the residues of distillation, however, can contribute significant lubricity and may be used widely in lubricant applications or added to petroleum fuels to decrease friction.
