Systems and methods are provided for producing naphthenic compositions corresponding to various types of products, such as naphthenic base oil, specialty industrial oils, and/or hydrocarbon fluids. The methods of producing the naphthenic compositions can include exposing a heavy fraction from a fluid catalytic cracking (FCC) process, such as a FCC bottoms fraction (i.e., a catalytic slurry oil), to hydroprocessing conditions corresponding to hydrotreating and/or aromatic saturation conditions. Naphthenic compositions formed from processing of FCC fractions are also provided.
A method for processing a product fraction from a fluid catalytic cracking (FCC) process, comprising:
A naphthenic base oil composition, comprising 500 wppm or less sulfur, 18 mol % to 30 mol % paraffinic carbons, 50 mol % or more of naphthenic carbons, a kinematic viscosity at 100° C. of 2.0 cSt to 30 cSt, a viscosity index of 25 or less, and a T5 distillation point of 260° C. or more.
A naphthenic base oil composition, comprising 500 wppm or less sulfur, 18 mol % to 30 mol % paraffinic carbons and 60 mol % or more of naphthenic carbons, the naphthenic base oil composition further comprising:
