How to recycle black engine oil to diesel?
Recycle black engine oil to dieselBlack engine oil and biofuels are two important alternative fuel sources proved to be the best substitutes for existing petrofuels, since black engine oil represent more than 60% of used engine oils. Therefore, black engine oil is one of the most abundant pollutant residues that is generated nowadays, reaching the value of 24 million metric tonnes per year. In recent years, recycling of the black engine oil and utilizing of the products asdiesels have become important topics for researchers.
Most of the black engine oil is generally obtained from petroleum resources. Petroleum-derived base oils currently account for about 97% of the total lubricant production. However, these oils become black engine oil harmful for environment after a certain time period. Recycling of the black engine oil by purifying and converting them into diesel is very important in terms of protection of the environment.

Millions of tons of black engine oil is disposed through dumping on the ground or in water, land filling, or non-energy-recovery. The used or black engine oil can be refined and treated to produce diesel or lubricating oil base stock. On the other hand, the black engine oil pose an environmental hazard due to both their metal content and other contaminants.
The high-volume black engine oil can be turned into valuable diesel products by refining and treating processes. Converting of the black engine oil into diesel to be used in engines without disposing is very important.
Utilization of the diesel produced from the black engine oil, and blending of the produced diesel with gasoline or turpentine decrease consumption of petroleum based fuels, protecting environment from toxic and hazardous chemicals. It also saves of foreign exchange, reduces greenhouse gas emissions and enhances regional development especially in developing countries.
