Abstract: Provided herein are methods and systems of making a high quality isoparaffinic base stock which include contacting an adsorbent material with a hydrocarbon feedstock and a solvent and separating at least some of the one or more high VI components from the hydrocarbon feedstock to produce a first fraction base stock having a first fraction base stock viscosity index. The adsorbent material is desorbed with a second solvent to produce a second fraction base stock having a second fraction base stock viscosity index. In these methods, the first fraction base stock viscosity index is less than the hydrocarbon feedstock viscosity index and the second fraction base stock viscosity index is greater than the hydrocarbon feedstock viscosity index.

Abstract: A process for separating one or more one-ring cycloparaffins and one or more multi-ring cycloparaffins from a hydrocarbon mixture is disclosed. The process comprises the steps of providing the hydrocarbon mixture; and contacting the hydrocarbon mixture with an adsorbent material comprising a metal organic framework to separate the one or more one-ring cycloparaffins and the one or more multi-ring cycloparaffins from the hydrocarbon mixture. The process is conducted in a liquid phase.

Abstract: This disclosure provides methods for separating multi-ring naphthenes from a hydrocarbon feedstock. The hydrocarbon feedstock includes at least normal paraffins, isoparaffins, 1-ring naphthenes attached with a paraffinic alkyl chain, and multi-ring naphthenes. The methods comprise passing the hydrocarbon feedstock and a solvent, at a temperature and pressure through a bed of an adsorbent comprising a metal-organic framework (MOF) adsorbent, to adsorb the multi-ring naphthenes from the hydrocarbon feedstock, thereby producing a base stock product that is depleted in multi-ring naphthenes. The metal-organic framework adsorbent is a porous crystalline material comprised of metal functionalities connected by organic linkers to form a repeating 2-D or 3-D lattice. The base stock product has a viscosity index (VI) greater than the viscosity index of the hydrocarbon feedstock. The methods of this disclosure upgrade Group II base stocks (also Group II+ base stocks) to Group III or Group III+ base stocks, and also upgrade Group III base stocks to Group III+ base stocks.
