Abstract:
The production and use of biolubricants as replacements for mineral lubricants align with the promotion of sustainable development goals, contributing to the sustainable economic growth of developing countries as well as the preservation of the environment. The implementation of biorefineries (where the production of biolubricants through transesterification could play an important role) is becoming important for these purposes, using natural feedstocks such as rapeseed, which is an interesting crop that can adapt to different climates under extreme weather conditions. The aim of this research

Abstract:
Plant oil derived compounds have been used as the raw material for the synthesis of green biolubricant. Azelaic acid derived from oleic acid is one of the interesting compounds. The synthesis of azelate esters oil based synthetic green biolubricants was carried out. The esterification process of azelaic acid with variety type of alcohols was catalyzed by concentrated H2SO4. The yields percentages of azelate esters oil produced were varied depending their overall molecular structure. The azelate esters oil properties were evaluated for their suitability as a biolubricant. The results showed tha

Abstract:
The term biolubricant applies to all lubricants that are easily biodegradable and non-toxic to humans and the environment. The uses of biolubricant are still very limited when compared to those of mineral oils, although this trend is increasing and depends on investment in research and development (R&D). The increase in demand for biodegradable lubricants is related to the evolution of environmental regulations, with more restrictive rules being implemented to minimize environmental impact caused by inappropriate disposal. This study provides an overview of the types, production routes, pr

Abstract:
The constant utilization of petroleum-based products has prompted concerns about the environment, hence a replacement for these products must be explored. Biolubricants are a suitable replacement for petroleum-based lubricants as they provide better lubricity. Biolubricant performance can be improved by the addition of graphene. However, there are reports that graphene is unable to form a stable suspension for a long period. This study used a graphene-ionic liquid additive combination to stabilize the dispersion in a biolubricant. Graphene and ionic liquid were dispersed into the biolubricant

Abstract:
Vegetable oils lack acceptable thermo-oxidative stability due to the presence of tertiary β-hydrogen in glycerol backbone of triglyceride molecule. Chemical modification methods may significantly improve the thermo-oxidative stability of vegetable oils derived biolubricants without hindering their environmentally benign characteristics. This study was aimed at evaluation of thermo-oxidative stability of non-edible karanja oil derived biolubricant base oil. The biolubricant karanja oil trimethylolpropane ester (KOTMPE) was synthesized by conventional two step transesterification process. Therma

Abstract:
The transesterification of rapeseed and castor oil methyl esters with different alcohols (2-ethyl-1-hexanol, 1-heptanol and 4-methyl-2-pentanol) and titanium isopropoxide as a catalyst, to produce biolubricants, was carried out. Parameters such as temperature, alcohol/methyl ester molar ratio, and catalyst concentration were studied to optimize the process. The reaction evolution was monitored with the decrease in FAME concentration by gas chromatography. In general, the reaction was almost complete in two hours, obtaining over 93% conversions.

Abstract:
The performance of the previously optimized magnetic cross-linked enzyme aggregate of Eversa (Eversa-mCLEA) in the enzymatic synthesis of biolubricants by transesterification of waste cooking oil (WCO) with different alcohols has been evaluated. Eversa-mCLEA showed good activities using these alcohols, reaching a transesterification activity with isoamyl alcohol around 10-fold higher than with methanol. Yields of isoamyl fatty acid ester synthesis were similar using WCO or refined oil, confirming that this biocatalyst could be utilized to transform this residue into a valuable product. The eff

Abstract:
Biolubricants, though an answer to depleting mineral oil reserves and toxic pollutants seeping into the environment, have several drawbacks. They have a limited range of viscosities, poor low temperature properties, and reduced oxidative stability. Rubber seed oil, a nonedible oil extracted from rubber ( Hevea brasiliensis Muell. Arg) seeds, has been observed to serve as a good base stock for developing a novel biolubricant. This study aims at improving the properties of rubber seed oil, namely, its free fatty acid content, viscosity, cloud and pour point, tribological properties, and oxidativ
