Systems and methods are provided for conversion of oxygenate feeds to lubricant and/or distillate boiling range compounds with desirable properties by first selectively converting oxygenates to light olefins and then converting the light olefins to distillate and lubricant boiling range compounds with beneficial properties. The distillate boiling range products can have an unexpectedly high cetane, while the lubricant boiling range products can have an unexpectedly high viscosity index. The ability to form the distillate boiling range products and lubricant boiling range products is facilitated by using a Ni-enhanced oligomerization catalyst.

The present invention provides a low viscosity poly-α-olefin lubricating oil and a synthesis method thereof. The method comprises: (1) the α-olefin raw material is subjected to dehydration treatment so that the water content in the raw material is ≤10 ppm; (2) a reaction of the dehydration treated α-olefin raw material is carried out in the presence of a complex catalyst and gaseous BF.sub.3 to obtain a reaction product, wherein the pressure of the gaseous BF.sub.3 is 0.01 to 1 MPa; (3) the reaction product obtained in step (2) is sequentially subjected to flash distillation, gas stripping, centrifugation, and washing treatment to obtain an intermediate product; (4) the intermediate product obtained in step (3) is subjected to distillation under reduced pressure to separate the unreacted α-olefin raw material and α-olefin dimers, and the remaining heavy fractions are subjected to hydrogenation saturation treatment followed by fractionation and cutting-off.

Aromatics extraction and hydrocracking processes are integrated with a stream pyrolysis unit to optimize the performance of the hydrocracking units by processing the aromatic-rich and aromatic-lean fractions separately in order to better control the hydrocracking operating severity and/or catalyst reactor volume design requirements.

The invention describes a process for the capture of organometallic impurities in a hydrocarbon feedstock of gasoline type containing olefins and sulfur, in which a capture body is brought into contact with the feedstock to be treated and a stream of hydrogen, said capture body comprises an active phase based on nickel oxide particles with a size of less than or equal to 15 nm, said active phase not comprising other metal elements of Group VIb or Group VIII, which are deposited on a porous support chosen from the group consisting of aluminas, silica, silicas/aluminas, or also titanium or magnesium oxides, used alone or as a mixture with alumina or silica/alumina.

An improved alkylation process with improved octane number and lower final boiling point. Further, the present disclosure comprises an alkylation system that allows flexibility in the operating parameters without loss of productivity. This enhances the advantage of the solid acid alkylation process of the invention over the liquid acid processes, as the C9+ alkylate will mainly contain the desired highly branched paraffin's in the case of solid acid alkylation. By fractionation of C9+, the RON number of the gasoline alkylate after fractionation remains very high, while the final boiling point of the gasoline fraction will decrease, improving value and blending flexibility.

The present disclosure is directed to methods of producing zincoaluminosilicate structures with AEI, CHA, and GME topologies using organic structure directing agents (OSDAs), and the compositions and structures resulting from these methods.

The present invention relates to a process for converting vegetable oils, animal fats, residual edible oils and carboxylic acids into renewable liquid fuels, such as bionaphtha, bioJET-A1 and renewable diesel, for use in a mixture with fossil fuels. The process consists of two steps: hydrotreating and hydrocracking. The effluent from the hydrotreatment step presents aromatics, olefins and compounds resulting from the polymerization of esters and acids in its composition. This fact occurs due to the use of partially reduced catalysts and without injection of sulfide agent and allows obtaining a bioJET-A1 with adequate quality for use in a mixture with fossil kerosene. At the same time, the process generates, in addition to products in the distillation range of naphtha, kerosene and diesel, high molecular weight linear paraffins (with up to 40 carbon atoms).

The invention relates to a process for the hydrodesulfurization of a sulfur-containing olefinic gasoline cut in which said gasoline cut, hydrogen and a regenerated catalyst are brought into contact, said process being carried out at a temperature of between 200° C. and 400° C., a total pressure of between 1 and 3 MPa, an hourly space velocity, defined as being the flow rate by volume of feedstock relative to the volume of catalyst, of between 1 and 10 h.sup.−1; and a hydrogen/gasoline feedstock ratio by volume of between 100 and 1200 SI/I, said regenerated catalyst resulting from an at least partially spent catalyst resulting from a process for the hydrodesulfurization of a sulfur-containing olefinic gasoline cut and comprises at least one metal from group VIII, at least one metal from group VIb and an oxide support.

Methods comprising contacting a residue comprising paraffinic, olefinic, and aromatic hydrocarbons with a polar solvent under conditions effective to extract at least a portion of the aromatic hydrocarbons from the residue into the polar solvent, thereby generating: an extract phase comprising the portion of aromatic hydrocarbons and the polar solvent; and, a raffinate phase comprising a majority of the paraffinic and olefinic hydrocarbons.

The present invention relates to a saturated aliphatic hydrocarbon compound composition having an evaporation loss of 4% by mass or less as determined by the Noack method, a kinetic viscosity at 100° C. of 6.5 mm.sup.2/s or less, and an average carbon number of 36 to 44, to a lubricating oil composition containing the saturated aliphatic hydrocarbon compound composition, and to a method for producing a saturated aliphatic hydrocarbon compound composition, including: a step 1 of oligomerizing an olefin to obtain an olefin oligomer; a step 2 of isomerizing the olefin oligomer to obtain an isomer; and a step 3 of hydrogenating the isomer.
