Achieving High Value Utilization of Bio-oil from Lignin Targeting for Advanced Lubrication

Abstract

High-value utilization of biomass has been driven by increasingly growing industrial demands. Herein, we offer a strategy composed of depolymerization and esterification reaction of lignin to transfer to bio-oil with high liquid yield (79.75~85.25%), which is demonstrated as a high performance lubricant. Overall, the bio-oil has the excellent lubrication properties, where a significant wear reduction of 97.6% was observed as compared with polyethylene glycol 200. Meanwhile, the more ether and less acid in bio-oil could improve the anti-wear properties. This work provides a new application of utilizing lignin in advanced lubrication systems.

Preparation and properties investigation of biodegradable poly (glycerol sebacate‐co‐gelatin) containing nanoclay and graphene oxide for soft tissue engineering applications

“…As is well known, biomaterials have attracted increasing attention during the past few decades due to their crucial role in the food industry, 1 wastewater treatment, 2 energy storage devices, 3,4 tissue engineering, 5,6 and regenerative medicine 7–9 . Today, there is a growing interest in recovering biomass residues to produce efficient biomaterials such as lignin, 3,10 cellulose, 11 and protein 12 . Because of environmental protection goals, much research has been done on developing sustainable biofuels from lignin 10 or employing cellulose‐based materials as a flexible electrode component in wearable sensing or medical devices 4,9,11 .…”

It is a known fact that numerous native human tissues such as muscles, tendons, ligaments, and skin are soft and elastic.…”

B2O3/Al2O3 Nanocomposites as Lubricant Oil Additives to Save Friction-Induced Energy Waste

“…Researchers have explored in many ways to change the characteristics of the lubricant oils. [10][11][12][13][14][15] In particular, oxides are more and more used as lubricating oil additives because of their advantages in hardness, stability and morphology. [16][17][18] It is reported that boron oxide (B 2 O 3 ) and alumina (Al 2 O 3 ) nanoparticle additives can improve lubrication properties of lubricant oil prominently.…”

Textile Fabrics Containing Recycled Poly(ethylene terephthalate), Oyster Shells, and Silica Aerogels with Superior Heat Insulation, Water Resistance, and Antibacterial Properties

“…It is estimated that there will be 12 billion tons of plastic waste in the world by 2050. Thus, there is an urgent need to identify solutions for recycling and/or reusing this material. − At present, poly­(ethylene terephthalate) (PET) is the most common plastic-bottle waste. PET is incredibly tough and lightweight, while also exhibiting high tensile impact strength, abrasion resistance, and processing performance. , PET is recyclable but with a slight decrease in its mechanical properties after each cycle.…”
