Despite the pandemic, the base oil market has shown positive dynamics in recent years. The motor oil market also experienced impressive growth. Industrial organizations in the USA, Europe, Japan regularly introduce new standards and increase the requirements for automotive oils in terms of harmful emissions, energy saving and additional engine protection. That is, they update the specifications for ash content, the content of salts, sulfur, paraffin and metals in the product.
Base mineral oils are usually obtained directly from oil refineries. These are oil categories I-III according to the classification of the American Petroleum Institute (API). The main difference between them is in the degree of purification and methods of processing of raw materials, which affect the chemical composition (presence of impurities) and physical properties (viscosity).
Commercial synthetic oils (lubricants) are produced using base oil as a feedstock material by compounding and mixing with functional additives. The quality of the final product depends on many parameters: the quality of the feedstock, the base oil, and the technology of its production. Hydrogenation processes play a key role in this.
