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.

Liquid phase adsorptive separation of cycloparaffins from hydrocarbon mixture

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.

Adsorptive process for separation of isoparaffinic lube base stock from lower quality oils

A method for separating classes of hydrocarbon compounds from a feed stream including a hydrocarbon mixture is disclosed. The method includes the steps of passing a feed stream through a plurality of separation units arranged in a series in any order, wherein each separation unit has an adsorbent material; and separating classes of hydrocarbon compounds from the feed stream. When one of the plurality of separation units comprises an adsorbent material that is a metal organic framework selected from a zirconium, hafnium, cerium, or titanium-based metal organic framework, then another plurality of separation units includes an adsorption material that is different from the metal organic framework. The method is conducted in a liquid phase. The method can also use a single separation unit with a continuous cyclic bed apparatus. The method can be combined with refining and downstream processes.

Advanced adsorptive separation processes for molecular class separation

A molecular separation method can include: passing a deasphalted oil stream through a reactor containing an active substrate, wherein the catalytic active substrate adsorbs heteroatom species from the deasphalted oil stream and produces a pretreated hydrocarbon feed stream essentially free of 4+ ring aromatic molecules (ARC 4+ species), metal species, and heteroatom species; and chromatographically separating with a simulated moving bed apparatus or a true moving bed apparatus (SMB/TMB) the pretreated hydrocarbon feed stream into a saturate fraction and an aromatics fraction.

Molecular separations process

Catalysts including at least one microporous material (e.g., zeolite), an organosilica material binder, and at least one catalyst metal are provided herein. Methods of making the catalysts, preferably without surfactants and processes of using the catalysts, e.g., for aromatic hydrogenation, are also provided herein.

Catalysts and methods of making the same

Disclosed are methods and apparatuses for separating a wax product from a hydrocarbon feedstream by a) conducting a hydrocarbon feedstream to a membrane separation zone; b) retrieving at least one retentate product stream from the first side of the membrane element; c) retrieving at least one permeate product stream having a wax phase and an oil phase from a second side of the membrane element, wherein a pour point of the wax phase of the permeate product stream is higher than a pour point of the oil phase of permeate product stream; and d) separating a wax product from the wax phase of the permeate product stream.

Methods for separating wax products from hydrocarbon feedstreams

Systems and methods are provided for performing selective catalytic reduction on engine exhaust using ethanol from the engine fuel as the reducing agent. Fuel from a fuel tank or other fuel source can be passed through a separation module to produce a fuel stream with a reduced ethanol content and an ethanol-enriched fraction. After combustion of fuel under lean conditions, the combustion exhaust can be exposed to a catalyst system in the presence of the ethanol-enriched fraction.

Treatment of combustion exhaust

Systems and methods are provided for performing on-board separation of a fuel into a higher octane fuel fraction and a lower octane fuel fraction using a membrane under osmosis conditions. By performing the separation under osmosis conditions, the feed for separation can be exposed to the membrane without requiring prior heating. This can avoid the need for having a separate heat exchanger system for heating the feed to the membrane to a desired temperature range. Additionally or alternately, the permeate from the membrane separation can be at a pressure of roughly 100 kPa-a or higher. This can avoid the need for having an eductor to provide a pressure below 100 kPa-a for the permeate side of the membrane. The fuel fractions produced during the membrane separation can then be used as fuel in a dual-fuel spark ignition engine.

On-board separation process

Gas separation modules and methods for use including an integrated adsorbent and membrane. In certain refining applications, it is paramount to obtain high purity product gases. Adsorbent beds are effective at removing certain contaminants, such as CO, from gas streams containing product and contaminant constituents to form a product-rich stream. The integrated membrane permits a further separation of products from any unadsorbed contaminant to produce a high purity product, such as hydrogen, stream. The gas separation modules described herein include stacked, radial, and spiral arrangements. Each modules includes a configuration of feed and cross-flow channels for the collection of contaminant gases and/or high purity product gases.

Separation of gases using reactive adsorbents and membranes

In a process for separating one or more 3,3'-, 3,4&#x2032;- and 4,4&#x2032;-dimethyl biphenyl isomers, a feed comprising the isomers is contacted with a zeolite adsorbent which contains one or more metal cations in the +1 or +2 oxidation states. Separation processes for each of the 3,3&#x2032;-, 3,4&#x2032;- and 4,4&#x2032;-dimethyl biphenyl isomers is provided.

Processes for separating dimethyl biphenyl isomers using zeolite adsorbents

Asymmetric membrane structures are provided that are suitable for various types of separations, such as separations by reverse osmosis. Methods for making an asymmetric membrane structure are also provided. The membrane structure can include at least one polymer layer. Pyrolysis can be used to convert the polymer layer to a porous carbon structure with a higher ratio of carbon to hydrogen.

Reverse osmosis membranes and separations

A process for separating dimethyl biphenyl (DMBP) isomers, including contacting a mixture of 3,3'-DMBP, 3,4&#x2032;-DMBP and 4,4&#x2032;-DMBP in a first solvent with a 12-member ring zeolite exchanged with potassium or barium, or combinations thereof, and adsorbing the 3,3&#x2032;-DMBP onto the 12-member ring zeolite, such as by passing the mixture through at least one packed bed of the potassium and/or barium exchanged 12-member ring zeolite.

Adsorptive separation of dimethyl biphenyl regioisomers using 12-member ring zeolite sorbents

In a process for separating one or more 3,3'-, 3,4&#x2032;- and 4,4&#x2032;-dimethyl biphenyl isomers, a feed comprising the isomers is contacted with an adsorbent containing a zeolite having a largest diffuse along dimension of at least 4 Angstroms. The adsorbents provide selective adsorption of 4,4&#x2032;-dimethyl biphenyl.

Methods for coating a substrate with a coating including an adsorbent material and a binder comprising an organosilica material which is a polymer comprising independent units of Formula [ZZSiCH](I), wherein each Zrepresents a hydroxyl group, a C-Calkoxy group or an oxygen atom bonded to a silicon atom of another unit or an active site on the substrate and each Zrepresents a hydroxyl group, a C-Calkoxy group, a C-Calkyl group, an oxygen atom bonded to a silicon atom of another unit or an active site on the substrate are provided. Methods of gas separation are also provided.
