Book Description
Presents detailed information and study cases on experiments on hydrotreating catalysts for the petroleum industry Catalytic hydrotreating (HDT) is a process used in the petroleum refining industry for upgrading hydrocarbon streams—removing impurities, eliminating metals, converting asphaltene molecules, and hydrocracking heavy fractions. The major applications of HDT in refinery operations include feed pretreatment for conversion processes, post-hydrotreating distillates, and upgrading heavy crude oils. Designing HDT processes and catalysts for successful commercial application requires experimental studies based on appropriate methodologies. Experimental Methods for Evaluation of Hydrotreating Catalysts provides detailed descriptions of experiments in different reaction scales for studying the hydrotreating of various petroleum distillates. Emphasizing step-by-step methodologies in each level of experimentation, this comprehensive volume presents numerous examples of evaluation methods, operating conditions, reactor and catalyst types, and process configurations. In-depth chapters describe experimental setup and procedure, analytical methods, calculations, testing and characterization of catalyst and liquid products, and interpretation of experiment data and results. The text describes experimental procedure at different levels of experimentation—glass reactor, batch reactor, continuous stirred tank reactor, and multiple scales of tubular reactors—using model compounds, middle distillates and heavy oil. This authoritative volume: Introduces experimental setups used for conducting research studies, such as type of operation, selection of reactor, and analysis of products Features examples focused on the evaluation of different reaction parameters and catalysts with a variety of petroleum feedstocks Provides experimental data collected from different reaction scales Includes experiments for determining mass transfer limitations and deviation from ideality of flow pattern Presents contributions from leading scientists and researchers in the field of petroleum refining Experimental Methods for Evaluation of Hydrotreating Catalysts is an indispensable reference for researchers and professionals working in the area of catalytic hydrotreating, as well as an ideal textbook for courses in fields such as chemical engineering, petrochemical engineering, and biotechnology.

Book Description
Catalytic In-Situ Upgrading of Heavy and Extra-Heavy Crude Oils A comprehensive guide to a cutting-edge and cost-effective refinement process for heavy oil Oil sufficiently viscous that it cannot flow normally from production wells is called heavy oil and constitutes as much as 70% of global oil reserves. Extracting and refining this oil can pose significant challenges, including very high transportation costs. As a result, processes which produce and partially refine heavy oil in situ, known as catalytic upgrading, are an increasingly important part of the heavy oil extraction process, and the reduced carbon footprint associated with these methods promises to make them even more significant in the coming years. Catalytic In-Situ Upgrading of Heavy and Extra-Heavy Crude Oils provides a comprehensive introduction to these processes. It introduces the properties and characteristics of heavy and extra-heavy oil before discussing different catalysts and catalyzing processes, their mechanisms and underlying physics, and more. It offers the full sweep of description and analysis required for petroleum and chemical engineers to understand this vital aspect of the modern oil industry. Readers will also find: Detailed discussion of subjects including electron paramagnetic resonance spectroscopy, nuclear magnetic resonance spectroscopy, and more Analysis of both liquid catalysts and nanoparticle catalysts A numerical simulation of the catalytic in-situ oil upgrading process Catalytic In-Situ Upgrading of Heavy and Extra-Heavy Crude Oils is a valuable reference for petroleum and chemical engineers as well as advanced undergraduate and graduate students in related fields.

Book Description
"Upflow Moving Bed Hydrotreater (MBR) reactor is used for hydrotreating resid crude oil. It is a two-phase upflow reactor having a catalyst bed with conical bottom, and plena. At industrial conditions the reactor is not performing at its best and encountering issues such as hot spots, catalyst agglomeration inside the catalyst bed leading to frequent shutdown of the reactor. The root cause of these problems are linked to the improper hydrodynamics inside the catalyst bed. To investigate this, the industrial scale MBR is scaled down to a pilot scale and indicative and key hydrodynamic parameters are investigated using developed experimental methods and CFD simulation. The local hydrodynamics is quantified using an experimental technique called two-tip optical probe (TTOP). Developed algorithms for TTOP to derive the local phase saturations, velocities, backmixing, maldistribution using the time series data of the probe. The results indicates high maldistribution zones inside the catalyst bed and found convincing evidence to link this to the conical design and plena of MBR. Overall Gas and Liquid dispersion/Mixing in the catalyst bed is investigated by tracer studies using a developed methodology based on residence time distribution (RTD), Convolution, Regression, and Catalyst Bed Models based on axial dispersion and wave model. Good gas/liquid dispersion is seen at the industrial scaled down operating condition. A CFD model is developed for the lower plenum of MBR and validated with gamma ray densitometry (GRD) for radial profile of line average phase volume fraction. The simulation indicates that the current design of lower plenum is enabling a dominant movement of phases only in the central region outlets of this plenum. A modification of the current design proves to perform better in terms of movement of phases along entire outlets of the lower plenum"--Abstract, page iv.

Book Description
Many oil refineries employ hydroprocessing for removing sulfur and other impurities from petroleum feedstocks. Capable of handling heavier feedstocks than other refining techniques, hydroprocessing enables refineries to produce higher quality products from unconventional- and formerly wasted- sources.

Book Description
This handbook provides a comprehensive but concise reference resource for the vast field of petroleum technology. Built on the successful book "Practical Advances in Petroleum Processing" published in 2006, it has been extensively revised and expanded to include upstream technologies. The book is divided into four parts: The first part on petroleum characterization offers an in-depth review of the chemical composition and physical properties of petroleum, which determine the possible uses and the quality of the products. The second part provides a brief overview of petroleum geology and upstream practices. The third part exhaustively discusses established and emerging refining technologies from a practical perspective, while the final part describes the production of various refining products, including fuels and lubricants, as well as petrochemicals, such as olefins and polymers. It also covers process automation and real-time refinery-wide process optimization. Two key chapters provide an integrated view of petroleum technology, including environmental and safety issues.Written by international experts from academia, industry and research institutions, including integrated oil companies, catalyst suppliers, licensors, and consultants, it is an invaluable resource for researchers and graduate students as well as practitioners and professionals.
