摘要： 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.

摘要： A method of screening a hydrocarbon stream for potential toxicological hazards. The method involves providing a hydrocarbon stream; conducting 2-dimensional gas chromatography (2D-GC) analysis to quantify saturates and aromatic distribution in the hydrocarbon stream; identifying 2-8 ring aromatic distribution and weight percentage of 2-8 ring aromatic molecules in the hydrocarbon stream from the 2D-GC analysis; relating the weight percentage of 2-8 ring aromatic molecules in the hydrocarbon stream from the 2D-GC analysis to a mutagenicity index (MI), in which the MI is determined in accordance with ASTM Standard Method E 1687; and assessing a potential toxicological hazard of the hydrocarbon stream based on the weight percentage of 2-8 ring aromatic molecules in the hydrocarbon stream from the 2D-GC analysis and a MI threshold value. The 2-8 ring aromatic distribution preferably includes 3-6 ring aromatics, more preferably 3.5-5.5 ring aromatics. The 2-8 ring aromatic distribution includes mono alkylated and multi alkylated aromatic molecules.

摘要： Methods are provided for producing a plurality of lubricant base oil products with an increased overall yield. Prior to the final hydrocracking stage tor viscosity index uplift, a feed for making a lubricant base oil is fractionated in order to form at least a feed for making a lighter lubricant base oil and a feed for making a heavier lubricant base oil. The fractionation cut points are selected to so that the feed fraction for forming a light lubricant base oil has a higher Noack volatility and a lower viscosity than the desired targets for the lighter lubricant base oil. The feed fractions are then hydroprocessed separately to achieve desired properties.
