Abstract
Abstract: The enhanced anti-friction performance of novel additives derived from industrial olefin-rich naphtha (IORN) for ultra-low sulfur diesel (ULSD) has been reported in this study. Initially, IORN has been maleated with maleic anhydride in a pressure reactor to obtain alkenyl succinic anhydride (ASA). The ASA has been then esterified using various alcohols containing C<inf>2</inf> to C<inf>16</inf> alkyl chains to obtain a mixture of diesters. The friction-reducing capability of the diester blend in ULSD has been evaluated at different blending concentrations by HFRR. The diester derived from hexadecanol has demonstrated an improved anti-friction performance at a very low blending concentration of 150 ppm. Interestingly this diester exhibits better friction-reducing quality than other reported olefin-based additives. © Pleiades Publishing, Ltd. 2025.
