“…They highlighted that oxygen-carrying moieties enhance the lubricity and film strength of the additive. Additionally, Uchoa et al [54] observed that fatty compounds have better lubrication due to oxygen atoms, which provides polarity to the molecule and, consequently, adhesion to the metal surface; these oxygen-carrying moieties are present in the produced biodiesel.…”

This study investigates the performance of biodiesel produced from distilled waste tire pyrolytic oil through transesterification as a lubricant additive for aqueous drilling fluid systems. Aqueous-based drilling fluids have a high coefficient of friction as compared to oil-based drilling fluids. The inclusion of a biodiesel additive was for smooth application/operation. The friction-reducing physicochemical properties of the additive were analyzed and compared with the guidelinesof the United States specification (ASTM Standard) and the European specification (EN Standard). The chemical structure of the produced biodiesel was analyzed using gas chromatography–mass spectrometry (GC-MS). The results show that the distilled waste tire pyrolytic oil contains aliphatic, naphthenic, and aromatic hydrocarbons. The free fatty acid value reduced from 5.6% (for pyrolytic oil) to 0.64% after the transesterification process. A saponification value of 203.36 mg/g was recorded for the pyrolytic oil, and this value was also reduced to 197.35 mg/g after the transesterification process. The kinematic viscosity was reduced from 11.2 to 5.3 mm2/s for the obtained biodiesel, and this value is within the ASTM D6751 and EN 14214 standard values (1.9 to 6 and 3.5 to 5 mm2/s, respectively). The cetane number (47.75) was obtained for the biodiesel, and this is within the minimum range stipulated in ASTM D6751 guidelines. The produced biodiesel’s chemical structure analysis using GC-MS shows that it comprises of decanoic acid methyl ester and methyl ester. Furthermore, comparative analysis of the quantified friction-reducing physicochemical properties of the additive shows that the biodiesel produced from the distilled pyrolytic oil is a suitable additive for the improved lubrication of the friction-prone metallic parts of drill bits when water-based drilling fluids are employed for drilling oil and gas wells.

“…In this sense, glycerol has been applied as an additive in industrial processes or products with a large carbon footprint. For instance, E. Silva Santos et al used glycerol as an additive in emulsified marine diesel [291]. The authors reported an improvement of the lubricity and water reduction when a glycerol solution was added up to 15%.…”

Once a biorefinery is ready to operate, the main processed materials need to be completely evaluated in terms of many different factors, including disposal regulations, technological limitations of installation, the market, and other societal considerations. In biorefinery, glycerol is the main by-product, representing around 10% of biodiesel production. In the last few decades, the large-scale production of biodiesel and glycerol has promoted research on a wide range of strategies in an attempt to valorize this by-product, with its transformation into added value chemicals being the strategy that exhibits the most promising route. Among them, C3 compounds obtained from routes such as hydrogenation, oxidation, esterification, etc. represent an alternative to petroleum-based routes for chemicals such as acrolein, propanediols, or carboxylic acids of interest for the polymer industry. Another widely studied and developed strategy includes processes such as reforming or pyrolysis for energy, clean fuels, and materials such as activated carbon. This review covers recent advances in catalysts used in the most promising strategies considering both chemicals and energy or fuel obtention. Due to the large variety in biorefinery industries, several potential emergent valorization routes are briefly summarized.

“…However, the desulphurization process of diesel fuel has a negative impact, namely decreasing the lubricity ability of the fuel, due to the loss of compounds that are essential for its lubricity ability, such as polyaromatic and polar compounds [5]. The low lubricity properties of diesel fuel can speed up the wear and tear on vehicle engines [6]. The solution that can be applied to overcome this problem is by adding a substance to diesel fuel, which can increase its lubricity ability [7].…”

Desulphurization of diesel fuel is necessary to be done to reduce sulphur content in the air. However, the desulphurization process will reduce the lubrication properties of diesel fuel. In order to overcome the problem, it needs bioadditive to improve the lubricity. Lubricity of diesel fuel can be improved by the subsistence of chemical compound that is hydroxyethyl esther (HEE). HEE is synthesized through the transesterification reaction of palm oil (triglycerides) and 1,2 ethanediol at 150 °C for 5 hours and K2CO3 catalyst as well. The conversion of TG into the products is 72.90%. The characterization using Gas Chromatography-Mass Spectrometry (GC-MS) indicates that the chemical compound in synthesis products comprise free fatty acids, hydroxyethyl esters and by-products. The obtained products can be used as bioadditives to improve the lubricity of diesel fuel.
