Book excerpt: 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.

Download or read book Handbook of Petroleum Processing written by Steven A. Treese and published by Springer. This book was released on 2015-08-04 with total page 0 pages. Available in PDF, EPUB and Kindle. Book excerpt: This extensively updated second edition of the already valuable reference targets research chemists and engineers who have chosen a career in the complex and essential petroleum industry, as well as other professionals just entering the industry who seek a comprehensive and accessible resource on petroleum processing. The handbook describes and discusses the key components and processes that make up the petroleum refining industry. Beginning with the basics of crude oils and their nature, it continues with the commercial products derived from refining and with related issues concerning their environmental impact. More in depth coverage of many topics previously covered in the first edition, such as hydraulic fracturing or fracking as it is often termed, help ensure this reference remains a relevant and up-to- date resource. At its core is a complete overview of the processes that make up a modern refinery, plus a brief history of the development of processes. Also described in detail are design techniques, operations and in the case of catalytic units, the chemistry of the reaction routes. These discussions are supported by calculation procedures and examples, which enable readers to use today’s simulation-software packages. The handbook also covers off-sites and utilities, as well as environmental and safety aspects relevant to the industry. The chapter on refinery planning covers both operational planning and the decision making procedures for new or revamped processes. Major equipment used in the industry is reviewed along with details and examples of the process specifications for each. An extensive glossary and dictionary of the terms and expressions used in petroleum refining, plus appendices supplying data such as converging factors and selected crude oil assays, as well as an example of optimizing a refinery configuration using linear programming are all included to aid the reader. The 2nd edition of the Handbook of Petroleum Processing is an indispensable desk reference for chemists and engineers as well as an essential part of the libraries of universities with a chemical engineering faculty and oil refineries and engineering firms performing support functions or construction.

Download or read book Hydrotreatment and Hydrocracking of Oil Fractions written by B. Delmon and published by Elsevier. This book was released on 1997-01-20 with total page 594 pages. Available in PDF, EPUB and Kindle. Book excerpt: The symposium on Hydrotreatment and Hydrocracking of Oil Fractions aims to provide a global perspective and an inspection of the state-of-the-art of these processes. New American, European and Japanese environmental regulations call for advanced hydrotreatment processes for HDS and HDN for the removal of S- and Ni-components from oil fractions. These will alter the product slate of the oil refineries and the hydrocarbon composition of these products. Hydrocracking will play an important part in this shift. Adapting the operating conditions will not suffice to reach the desired product specifications and yields. Adequate catalysts will have to be developed. Powerful tools are now available for this, e.g. surface science techniques, molecular modeling and new types of reactors operated in a nonsteady mode. Another instrument in the improvement of hydrotreatment and hydrocracking units is the availability of more realistic kinetic models. These are based on a judicious insight into the reaction mechanism, also provided by the above-mentioned tools. Progress in the analytical techniques has allowed the reduction of the lumping of components in these kinetic models and first order kinetic equations are gradually replaced by equations accounting for the adsorption of the various components. More detailed and more realistic reactor models are now based on rigorous hydrodynamic models and their application has become possible through the rapidly increasing possibilities of computers.
