摘要：
An improved system and method for processing feedstocks in an ebullated-bed hydroprocessing reactor is provided in which hydrogen gas is dissolved in the fresh and recycled liquid feedstock by mixing and/or diffusion of an excess of hydrogen, followed by flashing of the undissolved hydrogen upstream of the reactor inlet, introduction of the feed containing dissolved hydrogen into the ebullated-bed hydroprocessing reactor whereby the dissolved hydrogen eliminates or minimizes the prior art problems of gas hold-up and reduced operational efficiency of the recycle pump due to the presence of excess gas in the recycle stream when hydrogen gas was introduced as a separate phase into the reactor.
摘要（中）：
提供了一种用于在沸腾床加氢处理反应器中处理原料的改进的系统和方法，其中通过混合和/或扩散过量的氢，将氢气溶解在新鲜和再循环的液体原料中，随后闪蒸未溶解的氢气上游 的反应器入口，将含有溶解氢的进料引入沸腾床加氢处理反应器中，由此由于存在过量的气体，溶解的氢消除或最小化现有技术的气体滞留问题和降低再循环泵的操作效率 当将氢气作为单独的相引入反应器时，在再循环流中。
