Micro- and milli process technologies constitute innovative continuous chemical approaches with highest impact on process intensification, dedication to sustainability, and large uptake by the chemical industries (European Roadmap of Process Intensification, 2008). Core device and system technology is here microstructured reactors with outer dimensions from fist to shoebox-size, meanwhile covering the whole range from laboratory (e.g. 1 l/h for single-phase liquid flows) to pilot (e.g. 100 l/h) range and even expanding in some cases to production scale (1000 l/h and more). The portfolio of IMM's reactor hardware includes also other innovative reactor concepts such as foams, tube and capillary reactors, etc. Integration of such devices to systems, e.g. to integrated micromixer-micro heat exchangers or even complete fuel processors, is IMM's expert knowledge. Core processing technology is Novel Process Windows (see e.g. www.dbu.de) which is an approach to tailor processes to have maximal use of the very high heat and mass transfer capacities of the microstructured reactors, while considering the need for shortening residences, e.g. to match throughput issues.
