阅读说明：本技术 热解焦油和闪蒸底部物的改质 (Upgrading pyrolysis tar and flash bottoms ) 是由 徐腾 K·坎德尔 K·J·伊曼纽尔 J·C·叶 G·S·康泰罗 于 2019-05-24 设计创作，主要内容包括：提供了用于共同处理热解焦油与热解前闪蒸底部物的系统和方法。在一些方面,共同处理可对应于溶剂辅助加氢处理。通过组合热解焦油和闪蒸底部物与溶剂,可减小或最小化与馏分的加氢处理有关的各种困难,例如与高粘度进料和/或高硫进料的加氢处理有关的困难。任选地,可使用单独的溶剂和/或稀释剂用于热解焦油和闪蒸底部物。所得改质产物可适合于例如包括在低硫燃油(LSFO)中。(Systems and methods for co-processing pyrolysis tar with pre-pyrolysis flash bottoms are provided. In some aspects, the co-processing may correspond to solvent assisted hydroprocessing. By combining pyrolysis tar and flash bottoms with the solvent, various difficulties associated with hydrotreating of fractions, such as those associated with high viscosity feeds and/or high sulfur feeds, may be reduced or minimized. Optionally, separate solvents and/or diluents may be used for pyrolyzing the tar and flashing the bottoms. The resulting upgraded product may be suitable for inclusion in Low Sulfur Fuel Oil (LSFO), for example.)
