This book explores the common approaches to upgrade heavy and extra-heavy crude oils by means of catalytic hydrotreating, emphasizing hydrogen addition technology as well as carbon rejection alternatives. Kinetic and reactor models are combined with experimental data to simulate and optimize commercial-scale reactor performance. Key Features- Focuses on fixed-bed catalytic hydrotreating and catalysts and process scheme characteristics for commercial application.- Guides readers on hydrotreating process technology development from batch reactor experiments to semi-commercial test.- Describes step-by-step methodologies for development of kinetic models based on experimental data generated at different reaction scales.- Provides detailed explanation on how to formulate a reactor model for the simulation of catalytic hydrotreating of heavy oils. A comprehensive guide to the upgrading of crude oils, this book has particular appeal for petroleum refining industry professionals, catalyst developers, workshop instructors, professors, and their graduate and postgraduate students.

This book provides an up-to-date treatment of all the important aspects of modeling of reactors employed in the main processes for heavy petroleum upgrading. It explains approaches to modeling catalytic reactors and discusses such aspects as thermodynamics, reaction kinetics, process variables, process schemes, and reactor design. To validate the models developed, the author uses experimental data obtained directly from the laboratory. This essential reference focuses on more practical issues regarding reactor modeling for upgrading of heavy petroleum and emphasizes detailed descriptions of catalytic reactor modeling.

During the upgrading of heavy petroleum, asphaltene is the most problematic impurity since it is the main cause of catalyst deactivation and sediments formation. Exploring many aspects related to asphaltenes composition and conversion, this book highlights the changes that these heavy and complex molecules undergo during catalytic hydroprocessing.
