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 catalyticaliy and/or solvent processed to form lubricant base stocks, including bright stocks that are resistant to haze formation.
Abstract:
Methods are provided for hydroprocessing a feed (such as hydrotreating, hydrocracking, or hydrofining a feed) to generate a product with a reduced or minimized aromatics content relative to the severity of the hydroprocessing conditions. In some types of hydroprocessing applications, it can be desirable to select the severity of hydroprocessing conditions to achieve a desired level of removal for sulfur, a desired level for removal of nitrogen, and/or a desired level for increasing the viscosity index of a feed. The severity for heteroatom removal and/or viscosity index uplift can also correspond to an amount of conversion of a feed to lower boiling point products, so the lowest severity conditions suitable for achieving a product quality can be desirable. By improving the aromatics saturation during hydroprocessing, the severity of subsequent aromatics saturation processes can be reduced.
Abstract:
This invention relates to methods for deoxygenation utilizing bulk metal catalysts feedstocks derived in part or whole from biological sources and alternatively, further hydrotreatment processing of such deoxygenated feedstocks. Feedstocks containing bio-derived feed components, and preferably additionally mineral oil feed components, are deoxygenated in a first stage or zone using a bulk metal catalyst. In additional embodiments, the deoxygenated feedstock effluent from the deoxygenation stage is further subjected to a hydrodesulfurization stage or zone.
Abstract:
Feeds containing triglycerides are processed to produce an olefinic diesel fuel product. The olefinic diesel can optionally be oiigomerized to form a lubricant base oil product. The olefinic diesel is generated by deoxygenating the triglyceride- containing feed using processing conditions that enhance preservation of olefins that are present in the triglycerides. The triglyceride-containing feed is processed in the presence of a catalyst containing a Group VI metal or a Group VIII metal and optionally a physical promoter metal.
Abstract:
An integrated process for producing naphtha fuel, diesel fuel and/or lubricant base oils from feedstocks under sour conditions is provided. The integrated process includes an initial dewaxing of a feed under sour conditions, optional hydrocracking of the dewaxed feed, and a separation to form a first diesel product and a bottoms fraction. The bottoms fraction is then exposed to additional hydrocracking and dewaxing to form a second diesel product and optionally a lubricant base oil product. Alternatively, a feedstock can be hydrotreated, fractionated, dewaxed, and then hydrocracked to form a diesel fuel and a dewaxed, hydrocracked bottoms fraction that is optionally suitable for use as a lubricant base oil.

Abstract:
Feeds containing triglycerides are processed to produce a diesel fuel product and propylene. The diesel product and propylene are generated by deoxygenating the triglyceride-containing feed using processing conditions that enhance preservation of olefins that are present in the triglycerides. The triglyceride-containing feed is processed in the presence of a catalyst containing a Group VI metal and a Group VIII non-noble metal and in the presence of CO.
Abstract:
Provided are processes for making hydrocarbons from renewable feed sources. In an embodiment, there is provided a method for co-producing lube basestock and transportation fuel from a feedstock of biological origin, the method including: a) converting a feedstock of biological origin to a ketone or a dimer acid in the presence of a first catalyst; and b) hydrogenating the ketone or the dimer acid to produce a hydrocarbon in the presence of a second catalyst comprising a hydrogenation catalyst and a hydrothermally stable binder.
Abstract:
Feeds containing triglycerides are processed to produce an olefinic diesel fuel product and propyiene. The olefinic diesel can optionally be oligomerized to form a lubricant base oil product. The olefinic diesel and propylene are generated by deoxygenating the triglyceride-contaming feed using processing conditions that enhance preservation of olefins that are present in the triglycerides. The triglyeeride-containing feed is processed in the presence of a catalyst containing a Group VI metal or a Group VIII metal and optionally a physical promoter metal.
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.
