In this study, an experimental bio-grease formulation composed of soybean and cottonseed oils (SBO &CSO) as base oil, lithium hydroxide thickener, and sugar cane filter cake wax (SCW) as an additive was presented. Properties such as viscosity, penetration, drop point, wear, and coefficient of friction (COF) for the formulated samples of bio-grease, were evaluated using standard methods, and the results were compared to the mineral grease. A mixture composition involving the lowest levels of relevant fatty acids in the base oils showed a good structure in the development of film formation a

This study explores the potential of vegetable oils as a sustainable alternative to mineral oils in grease formulation. The research focuses on producing bio-based greases using non-edible vegetable oils, specifically a blend of castor and jatropha oils in different proportions. Lithium hydroxide (LiOH) used as a thickener, while zinc dialkyldithiophosphate (ZDDP) additive was added to improve tribological properties of the bio- grease. According to factorial matrix, ten samples of bio-grease with different amount of base oil, thickener and additive were produced and tested for cone penetratio

The overwhelming cost of conventional lubricants has instigated the need for alternatives in the engineering industry. This study identified the physicochemical properties of Shea butter made from the shea nut and their application as a bio-grease in the food processing and industrial sectors. Some preliminary tests were conducted to ascertain the combination of materials that will produce grease with the right consistency as the commercial product. Results on its physicochemical properties showed that shea butter was suitable for use as lube base oil. Best bio-grease was obtained with mass co

The development of palm oil bio grease aimed to substitute grease made from petroleum with a material that is more environmentally friendly. The enhancement of bio grease characteristics can be performed by chemical synthesis. This research aimed to obtain best mole ratio of palm olein and H2O2 in the epoxidation process, and to analyze the physical characteristics of the bio grease products. This process used acetic acid and H2O2 with mole ratio variations of olein and H2O2 of 1: 3, 1: 6, and 1: 9. The mole ratio was selected based on the analysis of iodine and oxiran numbers, which was then

One commonly used lubricant in rolling bearings is grease, which consists of base oil, thickener and small amounts of additives. Commercial greases are mostly produced from petrochemical base oil and thickener. Recently, the development of base oils from renewable resources have been significantly focused on in the lubricant industry. However, to produce an entirely bio-based grease, the thickener must also be produced from renewable materials. Therefore, this work presents the design and evaluation of three different bio-based polymer thickener systems. Tribological tests are performed to cha

Harvesting large quantities of bananas produces tons of banana peel waste, which causes serious environmental problems in Egypt. Therefore, this study presented the transformation of banana peel waste into nanoactivated carbon for use as a nanoadditive in developing jojoba oil-based bio-grease. To extract nanoactivated carbon, banana peel waste (BP) was thermochemically treated by carbonization, activation, and combined activation/carbonization. The prepared samples were characterized using SEM and XRD. Particle sizes, as calculated by the XRD data for BP, Carbonized banana peels (CBP), carbon

Increasing interest in utilizing bio-lubricants has been sparked by pollution caused by the mineral oil-based lubricants and their depletion. This study aimed to assess the effectiveness of Jatropha oil based grease as a basis and sodium thickener as an additive. The grease's lubricating abilities were tested using the ASTM 2266 four ball test and molybdenum disulphide as an additive. According to the findings, adding molybdenum disulphide particles decreased wear and the coefficient of friction, with the latter falling by 69% when compared to virgin Jatropha grease. Given that Jatropha grease

This study presents utilization of the inedible by-product fat of the municipal massacres to formulate bio-based lubricant grease. Inedible animal fat of acceptable quality has been recovered through the wet rendering process. The recovered fat was sterilized and bleached using 200 ppm chlorine dioxide solutions. The acceptable saponification and iodine values of the fat emphasize that it can be used in the chemical industry as an oleochemical resource. The fat was fractionalized into two fractions; stearic and oleic. The lithium soap of the stearic fraction was employed as a thickener and the

Smörjmedel är en nödvändighet för maskiner för att minska slitage och energiförbrukning. Dock är över 95% av de använda smörjmedlen i dag fossilbaserade. Smörjmedel baserade på vegetabiliska oljor finns tillgängliga men har ofta en lägre oxidativ stabilitet och sämre lågtemperaturegenskaper än deras fossilbaserade motsvarigheter. Ett annat hinder att övervinna är att ersätta vanligt använda förtjockningsmedel i halvfast smörjmedel med biobaserat alternativ vilket också visat sig vara en utmanande uppgift.

Most of the rolling element bearings are lubricated with Grease lubricant. Generally, the grease is expected to serve for life. The major causes of the bearing failure are due to the failure of the lubrication. The grease will experience creeping, oil permeation, oil separation etc. The separated oil will be lost permanently from the bearing. The widely used grease for general application is the lithium grease. The thickener of the grease consists covalent bond. When the grease is sheared, the breakage of the covalent bond will be permanent, resulting in the permanent loss of the rheological p

Abstract Coatings for substrates used in the packaging industry have recently undergone a substantial transformation with the push to promote environmentally friendly or “green” products. This distinct change of direction has transcended from non-renewable materials derived from fossil fuels which are pollutants to bio-based renewable-resource-derived products which, in comparison, drastically reduce greenhouse gas emissions and hazardous waste.
