    Abstract: The process comprises introducing a first portion of a feedstock containing at least 20 parts per million of nitrogen into a feedpreparation zone to reduce the nitrogen and sulfur contents thereof; treating the effluent from the feed-preparation zone to separate a hydrogen-containing light gas and a heavy bottoms fraction from the effluent; introducing the treated effluent into a hydrocracking zone; and introducing a second portion of the feedstock containing at least 20 parts per million of nitrogen into the hydrocracking zone at a plurality of points spaced along the length of the hydrocracking zone to provide an increasing amount of nitrogen along the length of the hydrocracking zone in the direction of flow through the hydrocracking zone. The nitrogen-containing feedstock is introduced into the hydrocracking zone at a plurality of points along its length to control effectively the rate of reaction in the hydrocracking zone. The heat of the controlled hydrocracking reaction is used effectively to reduce external heat supplied to the hydrocarbons prior to their entry into the hydrocracking zone.

    Abstract translation: 该方法包括将含有至少20ppm的氮的原料的第一部分引入进料制备区以降低其中的氮和硫含量; 处理来自进料 - 制备区的流出物，以从流出物中分离含氢轻质气体和重质底部馏分; 将经处理的流出物引入加氢裂化区; 并且在沿着加氢裂化区的长度间隔开的多个点处将含有至少20ppm的氮的第二部分原料引入加氢裂化区，以沿着加氢裂化区的长度沿着加氢裂化区的长度提供增加量的氮 通过加氢裂化区的流动方向。 将含氮原料沿其长度的多个点引入加氢裂化区，以有效控制加氢裂化区的反应速率。 受控加氢裂化反应的热量有效地用于减少在进入加氢裂化区之前向烃提供的外部热量。
