Friction and wear properties of biomass-derived oils via thermochemical conversion processes

Abstract Tribological properties of biomass-derived oils (bio-oils) were experimentally investigated, and the compared with that standard mineral used for lubrication purposes. Bio-oils obtained from fast pyrolysis (using poultry pine), gasification (“gasitar” using pine) hydrothermal liquefaction processes Scenedesmus Nannocholoropsis). The friction wear tests conducted a ball on disk tribometer test. results showed coefficient (COF) around 0.02 both gasitar bio-oil; whereas, catalytic non-catalytic had COF 0.1. measurements bio-oils lower followed by bio-oil “gasitar”. Nannocholoropsis highest amount wear, algal higher to other oils. chemical analysis indicated oxygen content, while nitrogenates. Gasitar hydrocarbon content nitrogenates making it favorable lubricating oil.
