##STR00001##

wherein the moiety X[(RO.sub.a)(QO.sub.b)] and the moiety Z are mechanically mixed; wherein the weight percentage of the moiety Z is about 1% to about 99% of the total weight of the catalyst. Furthermore, the present disclosure provides a tunable, low-temperature, energy-efficient process for hydrocracking plastics to form a fuel, a lubricant, or a mixture thereof.

The present invention relates to a process for preparing liquid hydrocarbons by the Fischer-Tropsch process integrated into refineries, in particular comprising recycling streams from the steam reforming hydrogen production process as the feedstock for the Fischer-Tropsch process.

Systems and methods are provided for catalytic hydroprocessing to form lubricant base oils. The methods can include performing high pressure hydrofinishing after fractionating the hydrotreated and/or hydrocracked and/or dewaxed effluent. Performing hydrofinishing after fractionation can allow the high hydrogen pressure for hydrofinishing to be used on one or more lubricant base oil fractions that are desirable for high pressure hydrofinishing. This can allow for improved aromatic saturation of a lubricant base oil product while reducing or minimizing the hydrogen consumption. The high pressure hydrofinishing can be performed at a hydrogen partial pressure of at least about 2500 psig (˜17.2 Mpa), or at least about 2600 psig (˜18.0 Mpa), or at least about 3000 psig (˜20.6 MPa). The high pressure hydrofinishing can allow for formation of a lubricant base oil product with a reduced or minimized aromatics content, a reduced or minimized 3-ring aromatics content, or a combination thereof.

A C.sub.31 renewable base oil is disclosed that is suitable as a base oil to provide low viscosity base oils, such as having both low Noack volatility and low CCS-30° C. viscosity and/or to provide low viscosity base oils at the same time having a combination of acceptable HTHS and KV100 to allow the industry's base oil blenders to formulate high quality engine oils, such as SAE grade 0W-20, 0W-16, 0W-12 or 0W-8.

The present invention describes improved processes for the synthesis of high value chemical products from low carbon syngas. In one aspect, a process for the production of chemicals is provided. The process comprises the following: feeding a feedstock comprising hydrogen and carbon monoxide to a liquid fuel production reactor, wherein the liquid fuel production reactor comprises a catalyst, thereby producing a product, wherein the product comprises a liquid phase and a solid phase, and wherein the liquid phase comprises C5-C23 hydrocarbons and oxygenated hydrocarbons, and wherein the solid-phase comprises C24-C45 aliphatic hydrocarbons, and wherein the liquid phase is between 51 percent by volume and 99 percent by volume of the product.

Provided is a novel catalyst comprised of an alumina, silica-alumina, and a zeolite containing base impregnated with Ni, Mo, and W. In one embodiment, the trimetallic catalyst is layered with a conventional hydrocracking pretreat catalyst to provide a catalyst combination useful in hydrotreating a feed to a hydrocracking stage.

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.

A process is disclosed for producing renewable products, such as a renewable base oil, from a feedstock of biological origin. The process includes subjecting a feedstock containing free fatty acids and fatty acid glycerides, wherein at least one hydrocarbon chain is unsaturated, to esterification reaction in the presence of an alcohol. An ester stream thereby obtained is then subjected to metathesis conditions in the presence of a renewable alkene to obtain a metathesis product. Separation of the metathesis product includes recovery of a fraction containing or consisting essentially of C16 fatty acid esters, which is subjected to ketonisation reaction conditions to produce long chain ketones, which after hydrotreatment meet requirements for a renewable base oil. Ketonisation reaction produces renewable alkene usable in metathesis reaction.

The present disclosure provides a diesel fuel component produced from feedstock of biological origin and a method for producing the same. The present disclosure provides diesel fuel blends containing the diesel fuel component of biological origin and at least one additional diesel fuel.

The present disclosure provides a marine fuel component produced from feedstock of biological origin and a method for producing the same. The present disclosure provides marine fuel blends containing the marine fuel component of biological origin and at least one additional marine fuel.
