Base stocks and lubricant compositions containing same
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. This can allow for formation of unexpected base stock compositions.
Enhanced distillate oil recovery from thermal processing and catalytic cracking of biomass slurry
A method for thermal processing and catalytic cracking of a biomass to effect distillate oil recovery can include, particle size reduction. slurrying the biomass with a carrier fluid to create a reaction mixture, slurrying a catalyst with a carrier fluid to create a catalyst slurry, heating the reaction mixture and/or the catalyst slurry, and depolymerizing the reaction mixture with the catalyst. The reaction mixture can undergo distillation and fractionation to produce distillate fractions that include naphtha, kerosene, and diesel. In some embodiments, thermal processing and catalytic cracking includes vaporization of the biomass followed by distillation and fractionation. In some embodiments, a resulting distillate can be used as a carrier fluid. In some embodiments, the method can include desulfurization, dehydration, and/or decontamination.

COMPOSITION OF ESTERIFIED LIGNIN IN HYDROCARBON OIL
The present invention relates to a composition comprising hydrocarbon oil and substituted lignin, wherein the lignin has been substituted by esterification and acetylation of the hydroxyl groups, wherein the hydroxyl groups are esterified with a C14 or longer fatty acid at a degree of substitution of at least 20%, wherein the hydroxyl groups are acetylated at a degree of substitution of at least 20% and wherein at least 90% of the hydroxyl groups of the lignin is substituted by esterification and acetylation. The composition is essentially free from free fatty acid.
Processes for producing fuels and biofertilizers from biomass and products produced
An IBTL system having a low GHG footprint for converting biomass to liquid fuels in which a biomass feed is converted to liquids by direct liquefaction and the liquids are upgraded to produce premium fuels. Biomass residues from the direct liquefaction, and optionally additional biomass is pyrolyzed using microwave pyrolysis to produce structured biochar, hydrogen for the liquefaction and upgrading, and CO.sub.2 for conversion to algae, including blue green algae (cyanobacteria) in a photobioreactor (PBR). Produced algae and diazotrophic microorganisms are used to produce a biofertilizer that also contains structured biochar. The structured biochar acts as a nucleation agent for the algae in the PBR, as a absorption agent to absorb inorganics from the biomass feed to direct liquefaction or from the liquids produced thereby, and as a water retention agent in the biofertilizer. The ratio of cyanobacteria to diazotrophic microorganisms in the biofertilizer can be selected so as to achieve desired total chemically active carbon and nitrogen contents in the soil for a given crop.
Dechlorination of mixed plastics pyrolysis oils using devolatilization extrusion and chloride scavengers
A process for dechlorination of a hydrocarbon stream and/or a hydrocarbon stream precursor comprising introducing the hydrocarbon stream and/or hydrocarbon stream precursor, a first zeolitic catalyst, and a stripping gas to a devolatilization extruder (DE) to produce an extruder effluent, wherein the hydrocarbon stream and/or hydrocarbon stream precursor comprises one or more chloride compounds in an amount of equal to or greater than about 10 ppm chloride, based on the total weight of the hydrocarbon stream and/or hydrocarbon stream precursor, and wherein the extruder effluent comprises one or more chloride compounds in an amount of less than the chloride amount in the hydrocarbon stream and/or hydrocarbon stream precursor.
