Book Review Catalyst Deactivation, edited by E.E. Petersen and A.T. Bell, Marcel Dekker Inc., New York and Basel, 1987, xi+356 pp., $89.75 (USA and Canada), $107.50 (other countries) ISBN O-8247-774 1-7 The phenomenon of catalyst deactivation is of such widespread occurrence that when one encounters a catalyst exhibiting stable activity one is pleasantly surprised. It is a major challenge to the skill of the catalytic chemist to identify in any particular case which of the many possible causes of deactivation is at work, and to know what steps must be taken to eliminate the problem. For many years, deactivation was considered as an act of God, something inherent in the nature of catalysis and to be tolerated with the best possible grace. Carbon deposition was long ago recognised as a major problem; the classical work of Maxted on catalyst poisons introduced chemical principles into the experimental observations; and the work of Boudart and Benson ushered in an era in which the sintering of metallic particles could be quantitatively measured. This book is based on the invited contributions to the Third International Symposium on Catalyst Deactivation and Poisoning (ISCDAP3) held in June 1985 at the Lawrence Berkeley Laboratory. The subject is divided into four sections: (1) Theory of Catalyst Deactivation; (2) Bimetallic Catalyst Stability; (3) Chemistry and Physics of Catalyst Deactivation; and (4) Structural and Chemical Stabilization of Catalysts. Each section comprises three articles of an authoritative nature: abbreviated titles and the names of the senior author are as follows: (1) Poisoning of Catalysts (Butt); Fouling of Catalysts (Petersen); and Sintering of Supported Metals (Wanke). (2) Characterization by Gas Titration (Menon); Bimetallic Stabilization Mechanisms (Dadyburjor); Role of Sulphur (Oudar). (3) Deactivation of Fuel Cell Catalysts (Ross); Homogeneous Catalysts (Warren); and Carbonaceous Residues {Bell). (4) Metals in Molecular Sieves (Gallezot); Microstructural Changes in Catalyst Particles (Schmidt); and Hydrodemetallation Catalysts (Hegedus). These various articles are a mine of information and will repay careful study by anyone working with technical catalysts, either in the laboratory or on the plant. The book stands as a testimonial to the advances made in recent years in the scientific investigation of catalyst deactivation; but more than this, it is a valuable source of information and a convenient summary of the present state of play.
