Hydrotreatment and Hydrocracking of Oil Fractions

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.

ADHD in Adults (2010)
EN NW EB DLISBN: 9781139005500 bzw. 1139005502, in Englisch, Cambridge University Press, Cambridge University Press, Cambridge University Press, neu, E-Book, elektronischer Download.
Lieferung aus: Vereinigte Staaten von Amerika, in-stock.
Although the phenomenon of ADHD (Attention-Deficit Hyperactivity Disorder) is well described in children, it is now thought that in up to 60% of cases the symptoms persist into adulthood. This volume reviews our growing knowledge of adult ADHD and presents a transatlantic perspective on the identification, assessment and treatment of the disorder. The introductory section covers the history of ADHD, as well as the epidemiology, consequences, gender differences and legal aspects. Detailed descriptions of the clinical features of ADHD in adults are then given to enhance the reader's clinical recognition and assessment. Subsequent sections cover treatment strategies, emphasising pharmacological, psychological and social interventions. Written and edited by experts internationally renowned for their work in ADHD, this is an essential resource for all mental health workers who encounter adults presenting with neurodevelopmental disorders.
