An improved process for making a bright stock base oil from a base oil feedstream comprising an atmospheric resid feedstock, and, optionally, a base oil feedstock, via hydroprocessing. The process generally involves subjecting a base oil feedstream comprising the atmospheric resid to hydrocracking and dewaxing steps, and optionally to hydrofinishing, to produce base oil product(s) including a bright stock grade base oil product having a viscosity of at least about 22 cSt at 100 C. The invention is useful to make heavy grade base oil products such as bright stock, as well as Group II and/or Group III/III+ base oils.

A process to produce olefinic products suitable for use as or conversion to oilfield hydrocarbons includes separating an olefins-containing Fischer-Tropsch condensate into a light fraction, an intermediate fraction and a heavy fraction, oligomerising at least a portion of the light fraction to produce a first olefinic product which includes branched internal olefins, and carrying out either one or both of the steps of (i) dehydrogenating at least a portion of the intermediate fraction to produce an intermediate product which includes internal olefins and alpha-olefins, and synthesising higher olefins from the intermediate product which includes internal olefins and alpha-olefins to produce a second olefinic product, and (ii) dimerising at least a portion of the intermediate fraction to produce a second olefinic product. At least a portion of the heavy fraction is dehydrogenated to produce a third olefinic product which includes internal olefins. Also provided is a process to produce paraffinic products suitable for use as or conversion to oilfield hydrocarbons which includes separating a Fischer-Tropsch wax into at least a lighter fraction and a heavier fraction, hydrocracking the heavier fraction to provide a cracked intermediate, and separating the cracked intermediate into at least a naphtha fraction, a heavier than naphtha paraffinic distillate fraction suitable for use as or conversion to oilfield hydrocarbons, and a bottoms fraction which is heavier than the paraffinic distillate fraction.

A combined hydrogenation process method for producing high-quality fuel by medium-low-temperature coal tar, wherein a medium-low-temperature coal tar is fractionated to obtain a final product through a thermal hydrocracking unit, a first atmospheric fractionation unit, a hydro-refining, unit, a vacuum fractionation unit, a diesel and wax oil hydro-upgrading unit, a wax oil hydro-cracking unit, a gasoline and diesel precious metal hydrogenation unit and a fourth atmospheric fractionation unit. The present invention can effectively improve the quality of naphtha, aviation kerosene and diesel products, and produce high-end products with high yield and high value, and thus it has a great prospect of promotion and application.

The present disclosure provides a system and method for converting crude oil to light hydrocarbon products useful as a chemical feedstock. The system may also include a conversion system, such as a steam cracking unit, that converts the chemical feedstock from the feed preparation system to useful hydrocarbon chemicals. Exemplary hydrocarbon chemicals produced by the conversion system include light olefins, such as ethylene, propylene, and/or butadiene.

A heavy fuel oil product consists essentially of a hydroprocessed product of a high-sulfur-content feedstock that is at least one of A) a feedstock that is non-compliant with ISO 8217: 2017; B) a feedstock that is of non-merchantable quality as a residual marine fuel oil, and C) an intermediate product obtained by hydroprocessing a feedstock that is non-compliant with ISO 8217: 2017 so that the intermediate product is compliant with ISO 8217: 2017 but has a sulfur content of from 0.5 wt. % or more, the hydroprocessed product having a final sulfur content (ISO 14596 or ISO 8754) of less than 0.5 wt. %.

A process for the production of sustainable aviation fuel (SAF) with low carbon intensity. The jet fuel is produced from the reaction of hydrogen from the electrolysis of water with captured carbon dioxide. The hydrogen and carbon dioxide are reacted to product a stream comprising carbon monoxide. Hydrogen and carbon monoxide are reacted to produce n-alkanes. Alkanes are hydroisomerized to produce sustainable aviation fuel with low carbon intensity.

Process for reforming a hydrocarbon feedstock comprising paraffins and naphthenes. A hydrocarbon feedstock is separated to produce a first fraction enriched in naphthenes and a second fraction that is enriched in paraffins. The first fraction is contacted with a first reforming catalyst in a first reactor that is maintained at a temperature and pressure that facilitates conversion of naphthenes to aromatics. The second fraction is contacted with a second reforming catalyst in a second reactor at a temperature and pressure that converts at least 50 wt. % of paraffins in the second fraction to olefins. The process produces a liquid hydrocarbon reformate product suitable for use as a blend component of a liquid transportation fuel.
