Synthesis and tribological studies of nanoparticle additives for pyrolysis bio-oil formulated as a diesel fuel
Xu, Yufu; Peng, Yubin; Zheng, Xiaojing; Dearn, Karl D.; … - In: Energy 83 (2015) C, pp. 80-88
The tribological behaviour of pyrolysis bio-oil with a synthesized nano-Lanthanum oxide (La2O3) additive was evaluated using a point contact four ball tribometer under different frictional conditions. Results were compared against a micro (μ)-La2O3 additive and an un-additised bio-oil as a...
