In this study, the effect of bio nanoparticles (biochar) was investigated on anti-wear properties of an industrial lubricant. In the first phase, nanoparticles were produced sugarcane bagasse charcoal by ball mill method. The production of biochar nanoparticles from sugarcane waste products as biological nanoparticles can be a step towards reducing environmental problems. The produced nanoparticles were evaluated by EDS and XRD tests. In the second phase, biochar nanoparticles produced with a concentration of 0.5% by weight was combined with Golden Speed 20W-50 oil used in the cooling system of bearing housing of oil and petrochemical pumps then were determined anti-wear properties, coefficient of friction and heat transfer coefficient (k) of blends. Based on the results, it was found that nano-lubricant with a concentration of 0.5 wt% has a good performance, In such a way that the reduction of its friction coefficient compared to the base oil at linear speeds of 0.15, 0.2 and 0.3 m/s was 26.67, 32.3 and 27.87%, respectively. Therefore, in the third phase of this nano-lubricant blend, the role of biochar nanoparticles in combination with oil was used to field the pump bearing housing. The results of elemental analysis showed that the erosive elements of iron, chromium, aluminum, tin, copper and lead related to the nano-lubricant blend were reduced compared to conventional oil. Due to its positive role in the wear and friction test, the application of these nanoparticles in combination with the oil used in the bearing housing of petrochemical pumps had a positive effect.
