What Is Group II Base Oil?


Group II base oils are produced using modern hydroprocessing and catalytic dewaxing technologies.

The process begins with crude oil feedstock that undergoes atmospheric fractional distillation before being further distilled in a vacuum distillation tower. Vacuum gas oil (VGO) leaves the distillation tower and flows to a hydrocracker for further processing.

Inside the hydrocracker, hydrogen is introduced to saturate the waxy vacuum gas oil molecules and remove impurities like sulfur, oxygen, nitrogen, and heavy metals. During the process, aromatic molecules are converted to saturated paraffin molecules in the presence of a catalyst and under extreme temperature and pressure.

After hydrocracking is complete, the stream of oil passes through a catalytic dewaxing process, where waxy paraffin molecules are chemically restructured into isoparaffins. These isoparaffins are more resistant to gelling and have much better low-temperature characteristics.

A hydro-finisher wraps up the final step in hydroprocessing. Inside the hydro-finisher, hydrogen is reintroduced into the stream of oil to remove any lingering aromatics and impurities, which results in a finished product with a high viscosity index (VI), excellent oxidation, and thermal stability.
