    摘要: A process for reducing or removing at least 90% of sulfur in a tall oil composition, e.g., to a level of 15 ppm or less is disclosed. The process employs at least a first desulfurization and a second desulfurization treatment in parallel or in series. The first treatment comprises adsorptive desulfurization, wherein the adsorbent material comprises silica adsorbent having an average pore size between 50-200 Å, BET surface area of at least 300 mm 2 /, pore volume of 1.20 to 3.00 cc/g, and a silanol [Si-OH] level of 0.5 to 5 unit/nm 2 . The second desulfurization treatment is selected from adsorptive treatment, heat treatment, distillation, extraction, oxidation, reduction, hydrogenation, and sulfur scavenging for a reduced sulfur content.

    摘要: The present invention is directed to a process for preparing a polymer modified bituminous binder composition in the substantial absence of crosslinking agents by heating a bitumen component in a stirred tank to a temperature from 185 °C to 221 °C; adding a block copolymer composition to the bitumen component while the bitumen component is being stirred to form a homogeneous mixture of the bitumen component and the block copolymer composition; and continuing to stir the homogeneous mixture while maintaining the temperature from 185 °C to 221 °C for a period of time from 4 hours to 30 hours thereby forming a cured polymer modified bituminous binder composition. The block copolymer composition utilized in the process comprises a diblock copolymer comprising one block of a monovinylaromatic hydrocarbon and one block of a conjugated diene having a peak molecular weight from 30,000 to 78,000 and a vinyl content from 35 to 80 mol percent based on the number of repeat monomer units in the conjugated diene block, and optionally one or more block copolymers comprising at least two blocks of monovinylaromatic hydrocarbon and at least one block of conjugated diene, the block copolymer selected from linear triblock copolymers having a peak molecular weight that is 1.5 to 3.0 times the peak molecular weight of the diblock copolymer, multiarm coupled block copolymers having a peak molecular weight that is 1.5 to 9.0 times the peak molecular weight of the diblock copolymer, and mixtures thereof, wherein each block copolymer has a vinyl content from 35 to 80 mol percent based on the number of repeat monomer units in the conjugated diene block, wherein when both (i) and (ii) are present in the block copolymer composition, the ratio of (i) to (ii) is greater than 1:1. The present invention is further related to an alternative to this process, a specific class of bituminous binder compositions and concentrates and a specific class of block copolymer compositions.
