Abstract
Oxidized disulfide oil (ODSO) compounds, derived from by-product disulfide oil (DSO) compounds from the MEROX process, are effective as lubricity additives for transportation fuels. Significant increases in lubricity of ultra-low sulfur fuels as measured by the WSD test were observed with addition of ODSO compounds in the range of from 0.1 ppmw to 10 ppmw. This use of ODSO compounds as lubricity additives converts an otherwise DSO waste oil product into a valuable commodity that has utility in improving lubricity properties of transportation fuels.
