  • Patent number: 10947464
    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.
    Type: Grant

  • Patent number: 10808185
    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.

  • Patent number: 10570342
    Abstract: Systems and methods are provided for solvent deasphalting of steam cracker tar. The resulting deasphalted oil produced from the steam cracker tar can then be hydroprocessed, such as hydrotreated and/or hydrocracked in a fixed bed reactor. The solvent deasphalting can correspond to a mild or trim deasphalting or can correspond to solvent deasphalting at higher solvent to oil ratios. Performing a trim deasphalting can reduce or minimize the amount of deasphalting residue that is formed as a product from the deasphalting process.

  • Patent number: 10550341
    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.

  • Publication number: 20170183578
    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.
