Abstract: Technical lignin compositions and pyrolysis methods for forming such technical lignin compositions from pyrolyzed biomass are provided. The technical lignin compositions can include at least about 50 wt % phenolic polymers and/or at least about 75 wt % combined phenolic monomers and phenolic polymers. In some aspects, less than about 50 wt % of the linkages between benzylic units in the phenolic polymers and/or in the composition can correspond to β-O-4 linkages. At least about 50 wt % of the hydroxyl groups in the composition can correspond to phenolic hydroxyl groups. At least about 60 wt % of the phenolic hydroxyl groups and/or phenolic ether groups can correspond to phenolic hydroxyl groups and/or phenolic ether groups in an ortho position relative to at least one substituent.

Abstract: Provided are marine lubricating oils including from 15 to 95 wt % of a Group III base stock having a kinematic viscosity at 100 deg. C. of 4 to 12 cSt, 0.5 to 55 wt % of cobase stock having a kinematic viscosity at 100 deg. C. of 29 to 1000 cSt, 0.1 to 2.0 wt % of a molydithiocarbamate friction modifier, 0.1 to 2.0 wt % of a zinc dithiocarbamate anti-wear additive, and 2 to 30 wt % of other lubricating oil additives. The cobase stock is selected from the group consisting of a Group I, a Group IV, a Group V and combinations thereof. Also provided are methods of making and using the marine lubricating oils.
