A Review of Process Aspects and Modeling of Ebullated Bed Reactors for Hydrocracking of Heavy Oils

摘要: The main characteristics of ebullated bed reactors have been reviewed in this work. Key factors the application these to hydrocracking heavy petroleum fractions, such as sediments formation, catalyst attrition and deactivation, clearly discussed. Mathematical representation systems has organized into hydrodynamics, scaling down reactor modeling. Only a few reports dealing with topic review were found literature, which employ different levels sophistication establish model equations. These literature summarized properly discussed, from it recognized that modeling is complex task deserves more attention.
