• Sommario/riassunto: This authoritative work represents a broad treatment of the field, including the basic principles of membrane reactors, a comparative study of these and conventional fixed-bed reactors or multi-tube reactors, modeling, industrial applications, and emerging applications -- all based on case studies and model reactions with a stringent mathematical framework. The significant progress made over the last few years in this inherently hot multidisciplinary field is summarized in a competent manner, such that the novice can grasp the elementary concepts, while professionals can familiarize themse
