Investigation on the lubricating behavior of cashew nut shell liquid oil as a renewable and reliable petrochemical product

In order to compact the ecological and harmful concerns of lubricants, it is necessary to focus on the environment-friendly oils as lubricants and manufacturing. Aforementioned studies reveal the significance of Cashew Nut Shell Liquid oil as renewable, biodegradable and non-toxic to the environment, hence the current study sought to explore the lubrication property of Cashew Nut Shell Liquid oil (CNSL) in comparison with base lubricant oil (SAE 20 W-40). In order to improve the lubrication in internal combustion engines, the study is conducted with various blends and the properties are evaluated as per ASTM standards. We believe ours is the first report to study the lubricating behavior of cashew nut shell liquid oil before and after pyrolysis process. Our study focuses on testing the CNSL oil according to the ASTM test standard and proposing the optimized blend for improving lubrication in IC engine by 8%. ? 2020 Elsevier Ltd. All rights reserved.
