Abstract:
The increasing environmental concerns and depletion of petroleum resources have intensified research into sustainable alternatives for conventional lubricants. This study presents a comprehensive comparative analysis of biolubricant base stocks derived from three major vegetable oil sources: soybean (Glycine max), rapeseed (Brassica napus), and palm oil (Elaeis guineensis). The research evaluates physicochemical properties, tribological performance, oxidative stability, and environmental impact of these bio-based lubricant formulations. Results indicate that rapeseed oil-derived base stocks demonstrate superior low-temperature performance with pour points of -15°C compared to soybean (-9°C) and palm oil (+3°C). However, palm oil derivatives exhibit enhanced oxidative stability with induction periods of 180 minutes versus 145 minutes for soybean and 160 minutes for rapeseed derivatives. The viscosity index values range from 185-210 for all three base stocks, significantly higher than conventional mineral oil lubricants. This comprehensive analysis provides valuable insights for industrial applications seeking environmentally sustainable lubricant alternatives while maintaining performance standards comparable to petroleum-based products.
