  • Patent number: 10287516
    Abstract: Systems and methods are provided for block operation during lubricant and/or fuels production from deasphalted oil. During “block” operation, a deasphalted oil and/or the hydroprocessed effluent from an initial processing stage can be split into a plurality of fractions. The fractions can correspond, for example, to feed fractions suitable for forming a light neutral fraction, a heavy neutral fraction, and a bright stock fraction, or the plurality of fractions can correspond to any other convenient split into separate fractions. The plurality of separate fractions can then be processed separately in the process train (or in the sweet portion of the process train) for forming fuels and/or lubricant base stocks. The separate processing can allow for selection of conditions for forming lubricant fractions, such as bright stock fractions, that have a cloud point that is lower than the pour point.

  • Publication number: 20090105103
    Abstract: A lubricating oil composition for use in oil-impregnated sintered bearings together with a resin member having C?C bonds or C?O groups in the molecules, which comprises a base oil comprising a synthetic hydrocarbon oil as the main component, and 0.1-30% by weight of an ester-based oil on the basis of total composition, and free from zinc dialkyldithiophosphate and molybdenum dialkyldithiocarbamate, where the synthetic hydrocarbon oil as the main component of the base oil has substantially no adverse effect on resin, can minimize an adverse effect on various metal species of sintered materials by suppressing a mixing amount of a wear inhibitor or an extreme pressure agent to a minimum, without deteriorating a good lubricability required for the lubricating oil in oil-impregnated sintered bearings.
