This book provides much information of interest to anyone working in the petroleum industry or studying catalyst preparation and characterization in industrial or university laboratories. It contains both review articles and papers reporting progress concerning hydrotreating catalysts which together provide an up-to-date picture of this interesting field. The use of modern spectroscopic techniques in catalyst characterization is described and new concepts such as microbial upgrading and the use of crystallography data in catalyst design are presented.
