Naphthenic process oils are made by blending one or more naphthenic vacuum gas oils in one or more viscosity ranges with a high Ccontent distilled aromatic extract feedstock to provide at least one blended oil, and hydrotreating the at least one blended oil to provide an enhanced Ccontent naphthenic process oil. The order of the vacuum distillation and blending steps may be reversed.

High performance process oil based on distilled aromatic extracts

Naphthenic process oils are made by blending one or more naphthenic vacuum gas oils in one or more viscosity ranges with a high Ccontent ethylene cracker bottoms, slurry oil, heavy cycle oil or light cycle oil feedstock to provide at least one blended oil, and hydrotreating the at least one blended oil to provide an enhanced Ccontent naphthenic process oil. The order of the vacuum distillation and blending steps may be reversed.

High performance process oil

A process for producing naphthenic bright stocks from low quality naphthenic crude feedstocks. The naphthenic bright stocks produced by the process have improved low temperature properties at high yields based on feedstock.

Process for producing naphthenic bright stocks

A process for producing naphthenic base oils from low quality naphthenic crude feedstocks. The naphthenic base oils produced by the process have improved low temperature properties at high yields based on feedstock.
