Micro process engineering is approaching both academia and industry. With the provision of micro devices and systems by commercial suppliers, one main barrier for using these units has been eliminated. More and more they become familiar, thereby being one facet of the upheaval in chemical industry.This book focuses on processes rather than on devices: what is 'before' and 'behind' micro device fabrication. A comprehensive and detailed overview is given on:A multi-faceted, hierarchic analysis of chemical micro process technologyModelling and simulation of micro reactorsLiquid- and liquid/liquid-phase reactionsGas/liquid reactionsGas-phase reactions (heterogeneous catalysis)
