1)‌ Cetane Number: This is an important to measure diesel’s combustion performance. The higher the value, the more full and complete the combustion, the stronger the explosive power of the engine, and the lower the fuel consumption rate. Cetane numbers usually range from 40 to 60 ‌2)Sulfur Content: Sulfur content is a measure of the sulfur content in diesel. The...

We can find that the sulfur content and aromatics content will reduce the quality of diesel oil, and the natural environment will be affected to a great extent. Therefore, at this stage, it is necessary to improve the quality of oil products and reduce their actual content, so as to effectively reduce environmental pollution and reduce harm to the human body. Sulfur content The element with the...

Hydrotreatment: under a certain temperature and pressure, diesel contact with hydrogen, the sulfur is converted into hydrosulfuric acid, then removed by pickling method. This method can effectively reduce the sulfur content in diesel, However the plantinvestment is large and the energy consumption is high. Solvent extraction method: choose an organic solvent that can form a substance with a...
