Abstract: | Microstructure reactors (microreactors) in recent decades became one of the most actively studied subjects of the reaction
equipment aimed at intensification of chemical processes and increase in their safety. It is not surprising because due to
miniature dimensions of microstructures which do not exceed 2 mm microreactors contribute to minimization of the material
at their production as well as raw material and energy in the process of exploitation. Moreover, due to acceleration of heat
and mass transfer the productivity of equipment with microreactors in a range of cases is significantly higher than classical
batch reactors applied in industry. The brief overview of the modern development and achievements of microreactor technology
is given in this article by an example of heterogeneous reaction systems which are different by their nature and occur in
different types of microreactors: phase-transfer catalysis, biocatalysis, and synthesis of nanoparticles. A special attention
in the article is paid to the aspects of intensification of the considered processes because exactly the possibility of intensification
makes microreactor technology attractive for the industry. |
