摘要

Lemon (Citrus limon) peel oil (LPO) possesses promising fuel properties that are suitable for application as an alternative to diesel. However, the low cetane number of LPO makes it less viable, but could be improved through efficient additive use, hydrotreatment, and optimized formulation through B10 blending. Previous research has explored the fuel properties of LPO, but no study has examined the fuel properties of hydrotreated lemon peel oil (HLPO) and its impact on physicochemical properties. Therefore, the study aims to optimize the HLPO-B10 blended green ternary fuel using a Central Composite Design of RSM to produce renewable diesel fuel with enhanced physicochemical properties. The Cetane index was determined through parametric variation of the HLPO volume (%), additive loading (%), and blending temperature (°C). The statistical analysis revealed that both the regression model and model terms showed statistical significance, with the predicted R2 confirming the adjusted value (< 0.2 difference). The study achieved a Cetane index of 50.77 (predicted value = 50.99) under optimal conditions of 20.94% HLPO volume, 3% additive loading, and 160 °C blending temperature, with remarkable improvement on physicochemical properties. The model validity and applicability were confirmed by the residual value of 0.22, indicating accurate response prediction. Evidently, the HLPO produced from waste lemon peels is a potentially viable alternative fuel supplement suitable as biodiesel extender for diesel engines due to its excellent low-temperature properties and hydrophobic nature. Overall, the study provides technical insights for creating cleaner bio-based alternative diesel fuel, promoting a more sustainable bio-solid-waste management system.
