The Importance of Recycling Used Oil into Diesel fuel?
- Fulfilling Oil Shortage and Assuring Energy Security: The recycling of waste engine oil into diesel helps relieve the oil shortage. With the faster growth of the economy, oil demand continues to rise. By converting waste engine oil into valuable diesel, wasteful resources are conserved, dependence on foreign oil is reduced, and national energy security is assured.
- Reduction of Environmental Pollution: Waste engine oil creates extremely severe environmental pollution if disposed of in the form of direct discharge or incineration. Recycling and regeneration of waste engine oil to diesel not only minimizes its negative environmental impact but also transforms waste into useful fuel.
- Developing Substantial Economic Benefits: Waste engine oil recovery to diesel has a strong market demand. It not only produces high-value products in this process, but also develops substantial economic benefits.

Working Process of YJ-DSL Lube Oil Refinery Plant
Oil contains many hydrocarbons of different sizes. Each type of hydrocarbon has unique properties, and therefore, oil is useful for the production of a range of products.
The cracking process is a key process in petroleum refining in which the heavy hydrocarbons are broken into smaller molecules. It is accomplished by exposing it to heat and pressure, at times with the addition of catalysts.
By cracking, the carbon–carbon bonds are broken, and heavier hydrocarbons are broken down to lighter hydrocarbons. It is one of the major methods in which used oil is processed into useful fuels such as motor gasoline, diesel oil, and heating oil.

Features of a YJ-DSL Lube Oil Refinery Plant
- High recovery rate: The highest recovery rate can reach 87-90%, including Gasoline 2-5%, diesel fuel 83-85%.
- Easy operation: The YJ-DSL series machine is easy to operate, low running cost, it needs only 2-3 workers to operate.
- Rich raw material: YANGJIANG’s YJ-DSL series can recycle all kinds of used black diesel, used engine oil, used machine oil, used mineral oil, and almost all industrial oil to diesel fuel. The cracked oil is able to be used as industrial or civil-use fuel, even power-driven fuel.
- Efficient catalyst: It is normally safe and available. It can help the waste oil undergo further catalytic cracking to ensure a higher recovery rate and good quality of oil. The output oil can be used in ships, generators, as fuel for boilers, construction machines, agriculture machines, etc., directly.
What Kinds of Catalysts We Use?
YANGJIANG has been committed to researching and developing new technologies, continuously breaking through the oil recycling technologies. We have discovered this liquid catalyst through continuous experiments. The catalyst is safe to use, it won’t cause machine coke, helps to get better diesel color and diesel smell, lower sulfur content, and pour point.
Many people use solid catalyst after distillation, we use it before, but the problem is that the catalyst is easy to block or coke when hot oil vapor passes through the solid catalyst. It is normally safe and available. It can help the waste oil undergo further catalytic cracking to ensure a higher recovery rate and good quality of oil.
