A hydrocracking system is upgraded by modifying an existing ebullated bed initially utilizing a supported ebullated bed catalyst to thereafter utilize a dual catalyst system that includes metal sulfide catalyst particles and supported ebullated bed catalyst. The upgraded hydrocracking system achieves at least one of: (1) hydroprocess lower quality heavy oil; (2) increase conversion of higher boiling hydrocarbons that boil at 524° C. (975° F.) or higher; (3) reduce the concentration of supported ebullated bed catalyst required to operate an ebullated bed ...
1. A method of upgrading a heavy oil hydroprocessing system to hydroprocess lower quality heavy oil, comprising: initially operating an ebullated bed reactor containing a supported ebullated bed catalyst to hydroprocess an initial heavy oil of first higher quality defined by at least one of boiling point, molecular weight, hydrogen-to-carbon ratio, asphaltene concentration, or concentration of sulfur, nitrogen and metals, the ebullated bed reactor including a liquid phase comprising the initial heavy oil, a solid phase comprising the supported ebullated ...
