Abstract The performance of both ebullated bed H-Oil vacuum residue (VR) hydrocracking and fluid catalytic cracking (FCC) of vacuum gas oils (VGO) is interrelated. The increase of H-Oil unit reaction temperature maximizes VR conversion and augments the aromaticity and density of the hydrocracked heavy oils. The FCC of VGO blends that contain more aromatic H-Oil VGOs is featured by a lower VGO conversion. It was found in this study that the reactivity of the H-Oil heavy oils depends on their molecular weight (T50) instead on their aromatics content as observed during catalytic cracking of straight run VGOs reported in other studies.

H-Oil 减压渣油加氢裂化强度对流化催化裂化装置性能的影响

摘要 沸腾床 H-Oil 减压渣油 (VR) 加氢裂化和减压瓦斯油 (VGO) 的流化床催化裂化 (FCC) 的性能是相互关联的。H-Oil 单元反应温度的增加使 VR 转化率最大化，并增加了加氢裂化重油的芳香性和密度。含有更多芳香族 H-Oil VGO 的 VGO 混合物的 FCC 具有较低的 VGO 转化率。在这项研究中发现，H-Oil 重油的反应性取决于它们的分子量 (T50)，而不是它们的芳烃含量，如在其他研究中报道的直馏 VGO 催化裂化过程中观察到的。
