Book Description
This Symposium on Catalyst Deactivation ensues those held at Berkeley (1985), Antwerp (1980) and Berkeley (1978).The three main topics emphasised at this most recent symposium were: the techniques used in deactivation studies, the mechanisms of catalyst deactivation, and modelling. With respect to the first, it became apparent that the study of deactivation faces even more difficulties than the characterization of fresh catalysts and the measurement of activity or selectivity, due to the multiplicity of interacting processes occurring during deactivation. Quite substantial progress has been made recently in the understanding of the mechanisms of various deactivation processes, particularly coking, and extra time was accorded to these topics at the symposium. The third topic corresponds to a problem which is very central to development studies and to the chemical engineering aspect of catalysis: it deals with the representativity of accelerated tests and the modelling of the deactivation phenomena.

Book Description
Catalyst Deactivation 1994 was an expansion of earlier, highly successful symposia. The objective of the symposium was to promote a scientific approach of the phenomenon of catalyst deactivation which will contribute to the development of catalysts which are less subject to structural transformations and more resistant to poisons and coke formation. These aspects are dealt with in 12 plenary lectures, 48 oral presentations and 35 poster papers, which were critically selected from an impressive response from some 30 countries. Both fundamental and applied aspects were covered. The deactivation of catalysts in important industrial processes like fluid bed catalytic cracking hydrotreatment, hydrodesulfurization, catalytic reforming, hydrodenitrogenation, steam reforming, hydrodemetallization, hydrocracking, Fischer-Tropsch synthesis, propane dehydrogenation, phthalic anhydride synthesis received considerable attention. Mechanisms of poisoning, sintering and coking were further investigated and modelled and new experimental techniques for the characterization and the quantification of deactivation were also introduced.--[Source inconnue].

Book Description
Catalyst Deactivation 1991 was an expanded version of earlier, highly successful symposia. The symposium featured invited and solicited papers including 4 plenary lectures, 78 oral presentations and 23 poster papers. Most of the papers are contained in this volume. The eight main topics emphasised at this most recent symposium were: deactivation mechanisms/phenomena (carbon deposition, poisoning, and sintering), methods (modeling and techniques), and important catalysts (hydrotreating, oxides, and zeolites). All of these areas were well represented as attested by the substantial number of papers contained in these proceedings. Four review papers based on the plenary lectures provide state-of-the-art perspectives on new thrusts in deactivation research and development.
