It cannot be used directly as diesel. If the oil deteriorates, it may not be fully burned, causing carbon deposits, affecting engine performance, etc. Light cycle oil is a kind of light oil, abbreviated as LCO in English. It is produced from the catalytic cracking (FCC) unit. It is an intermediate cycle material in crude oil production and can be used as fuel oil for large machinery, mines, ships, etc.
At present, it plays a decisive role in my country's domestic ship fuel market; light cycle oil is a type of diesel base oil, which can be processed into diesel through hydrodesulfurization and other processes and used to blend diesel.
With the continuous optimization of the processing technology of blending oil manufacturers, light cycle oil has been blended in the Southeast Asian origin. After importing, it can be directly used by marine ships. Compared with diesel oil, the indicators are: sulfur content, density Indexes such as and carbon residue are slightly larger, the cetane number is smaller, and the total aromatic content exceeds 50% (only other similar products whose aromatic components weigh more than non-aromatic components will be classified into the light cycle oil range). The main and auxiliary engines of power fishing boats and cargo ships can be used directly, and can be used to blend No. 0 ordinary diesel.
In the petroleum refining industry, light oil can refer to light distillate oil or light oil products. The former includes gasoline (or naphtha), kerosene (or jet fuel), light diesel (or atmospheric gas oil) and other fractions, as well as top oil, raffinate oil, etc., which mainly come from crude oil distillation, catalytic cracking, thermal cracking, Petroleum coking, hydrocracking and catalytic reforming equipment.
