Abstract: An ebullated bed hydroprocessing system is upgraded using a dual catalyst system that includes a heterogeneous catalyst and dispersed metal sulfide particles to hydroprocess opportunity feedstocks (i.e., lower quality heavy oils or lower quality feedstock blends) while maintaining or increasing the rate of production of converted products. The dual catalyst system improves the ability of the upgraded ebullated bed hydroprocessing system to accommodate and withstand negative effects of periodic use of opportunity feedstocks (e.g., without significantly increasing equipment fouling and/or sediment production). In some cases, an upgraded ebullated bed reactor using the dual catalyst system can hydroprocess opportunity feedstocks while decreasing equipment fouling and/or sediment production.

Abstract: An ebullated bed hydroprocessing system is upgraded using a dual catalyst system that includes a heterogeneous catalyst and dispersed metal sulfide particles to improve the quality of vacuum residue. The improved quality of vacuum residue can be provided by one or more of reduced viscosity, reduced density (increased API gravity), reduced asphaltene content, reduced carbon residue content, reduced sulfur content, and reduced sediment. Vacuum residue of improved quality can be produced while operating the upgraded ebullated bed reactor at the same or higher severity, temperature, throughput and/or conversion. Similarly, vacuum residue of same or higher quality can be produced while operating the upgraded ebullated bed reactor at higher severity, temperature, throughput and/or conversion.

Abstract: An ebullated bed hydroprocessing system is upgraded using a dual catalyst system that includes a heterogeneous catalyst and dispersed metal sulfide particles to increase rate of production of converted products. The rate of production is achieved by increasing reactor severity, including increasing the operating temperature and at least one of throughput or conversion. The dual catalyst system permits increased reactor severity and provides increased production of converted products without a significant increase in equipment fouling and/or sediment production. In some cases, the rate of production of conversion products can be achieved while decreasing equipment fouling and/or sediment production.
