摘要: Abstract The present study considers the potentials of well-known production syngas by steam methane reforming (SMR), operation within microstructured reactors. model a microchannel reactor is developed, including very fast kinetic reaction rates on coated catalytic walls module. By varying characteristic dimensions channels, and considering technical constraints design operating conditions, results demonstrate that SMR can be drastically miniaturized while maintaining its productivity without any additional pressure drop. Furthermore, reducing channel dimensions, it possible to suppress heat mass-transfer limitations enabling at thermodynamic equilibrium. A method for preliminary heat-exchanger reactors enables identify optimal channels number power needed reach process specifications.
