Abstract: A hydrocarbon fluid is disclosed that has a pour point of at most ?30° C., as measured by ASTM D5950, and that comprises at least 99 wt % of naphthenes and paraffins, based on the total weight of the hydrocarbon fluid, wherein the weight ratio of naphthenes to paraffins is at least 1, as measured by GC-MS, and wherein the paraffins consist essentially of isoparaffins, as determined by GC-FID. In addition, preferred uses of said hydrocarbon fluid are disclosed.

Abstract: A system and methods for manufacturing a base oil stock from a light hydrocarbon stream are provided. An example method includes cracking a light hydrocarbon stream to form an impure olefinic stream, separating water from the impure olefinic stream, and oligomerizing the impure olefinic stream to form a raw oligomer stream. A light olefinic stream from the raw oligomer stream and linear alpha olefins are recovered from the light olefinic stream. A heavy olefinic stream is distilled from the raw oligomer stream and hydro-processed to form a hydro-processed stream. They hydro-processed stream is distilled to form the base oil stock.

Abstract: Systems and methods are provided for integration of use deasphalted resid as a feed for fuels and/or lubricant base stock production with use of the corresponding deasphalter rock for gasification to generate hydrogen and/or fuel for the fuels and/or lubricant production process. The integration can include using hydrogen generated during gasification as a fuel to provide heat for solvent processing and/or using the hydrogen for hydroprocessing of deasphalted oil.

Abstract: Methods are provided for forming lubricant base stocks from feeds such as vacuum resid or other 510° C.+ feeds. A feed can be deasphalted and then catalytically and/or solvent processed to form lubricant base stocks, including bright stocks that are resistant to haze formation.

Abstract: Methods are provided for producing lubricant base stocks from deasphalted oils formed by sequential deasphalting. The deasphalted oil can be exposed a first deasphalting process using a first solvent that can provide a lower severity of deasphalting and a second deasphalting process using a second solvent that can provide a higher severity of deasphalting. This can result in formation of at least a deasphalted oil and a resin fraction. The resin fraction can represent a fraction that traditionally would have been included as part of a deasphalter rock fraction.

Abstract: Systems and methods are provided for reducing the end point of distillate fuel boiling range fractions while reducing or minimizing conversion of the distillate fuel to naphtha or light ends. To perform end point reduction, a distillate boiling range fraction is exposed to a conversion catalyst that has a total surface area of at least 200 m2/g, an average pore size of 12 Angstroms or more, and/or a low acidity, where the conversion catalyst includes a supported Group 8-10 metal, such as a supported Group 8-10 noble metal. Such a conversion catalyst can have improved activity for reducing end point of a distillate fuel fraction while reducing or minimizing conversion relative to 177° C. Performing end point reduction using such a catalyst can allow for increased yields of distillate fuel boiling range products by allowing increased amounts of heavy feed components to be included in the input to a distillate fuel processing train.

Abstract: Electro-kinetic separation processes for removing solid particles from hydrocracker process streams are provided herein.

Abstract: Systems and methods are provided for producing lubricant basestocks using a process flow that includes a conversion catalyst that can provide a desired improvement in viscosity index at a reduced or minimized amount of feed conversion. An initial processing stage can be used to produce a lubricant boiling range fraction with a reduced or minimized heteroatom content. After a separation, at least a portion of the lubricant boiling range portion can be exposed to a conversion catalyst that has an effective pore size of at least 8.0 Angstroms, a total surface area of at least 200 m2/g, and/or an Alpha value of 20 or less, where the conversion catalyst includes a supported Group 8-10 noble metal. The methods can allow for increased yields of high viscosity index lubricant boiling range products from a process flow for lubricant base stock and/or blend stock production.

Abstract: Methods are provided for forming lubricant base stocks from feeds such as vacuum resid or other 510° C.+ feeds. A feed can be deasphalted and then catalytically and/or solvent processed to form lubricant base stocks, including bright stocks. The catalytic processing can correspond to processing in at least two stages. The amount of conversion performed in each stage can be varied to produce bright stocks with various properties.

Abstract: Finished wax compositions with low aromatic content and high oil contents may be suitable for use in candle applications and/or food packaging and other food grade quality applications despite such high oil contents. Such wax compositions can reduce the need for wax refinement and/or post-processing, such as de-oiling, and increase the ease and efficiency of batch preparation and large volume manufacture.
