Lube base oil

Main points of mineral base oil lubricant base oil, synthetic base oil and vegetable oil base oil three categories.Mineral base oil is used widely, the dosage is very big (about 90%), but must use some applications of synthetic base oil and vegetable oil base oil products, thus making the two base oil to get rapid development.

Mineral oil base oil from crude oil refining.Lube base oil production process mainly includes: the atmospheric and vacuum distillation, solvent deasphalting, solvent refining, solvent dewaxing, clay or supplement hydrogenation refining.In 1995 revised the current standard of lube base oil, the main revised classification method, and increases the low setting and depth of refined special base oil standards.Mineral lubricating oil production, the most important thing is to choose the best oil.

The chemical composition of mineral base oil including high boiling point, high molecular weight hydrocarbon and non-hydrocarbon mixture.Its composition is commonly alkane (linear, branched chain, much branched chain), naphthene (single, double loop, polycyclic), aromatics (monocyclic aromatic hydrocarbons, polycyclic aromatic hydrocarbons), ring alkyl aromatics and oxygen, nitrogen and sulfur containing organic compounds and non-hydrocarbon compounds such as colloid and asphaltene.
