Recycling of used engine oil using composite solvents and cashew bark activated carbon extraction technology
This research studies the recycling of 6 months used engine oil, using activated carbon from Cashew tree (Anacardium occidental) bark. The recycling process of the used engine oil, eventually led to comparison of results of the recycled engine oil with the fresh engine oil using ASTM standards. Test carried out on the used engine oil, fresh engine oil and the recycled engine oil include: viscosity at 40 and 100 °C respectively, specific gravity (Sp.g), flash point (FP), and fire point. The results shows that the recycled engine oil had the following physiochemical properties: viscosity at 40 °C was 137.01CSTmmSec-1, viscosity at 100 °C was 13.50CSTmmSec-1, specific gravity (Sp.g) was 0.8957gcm-3, flash point was 225.01 °C, fire point was 330.71 °C; This result shows an improvement in the physiochemical properties of the recycled engine oil.
