Current scenario and prospects in manufacturestrategies for glass, quartz, polymers and metallicmicroreactors: A comprehensive review

Abstract

tOne of the most remarkable benefits of the microreactors is the achievement of more effi-cient processes by enhancing the heat and mass transfer phenomena, which is the key factorfor processes intensification in chemical reactions, resulting in higher conversion, selec-tivity and yield towards desired products. Currently, the entire scenario of microreactionapproach is an emergent technology and further advances are ongoing. Several strategieshave been successfully applied for structuring processes that imply the fixation of the cata-lysts on the microreactors. However, there are features such as the physicochemical stabilityof the coatings under reaction conditions that must be improved, motivating the search fornew protocols. This review provides a general overview of the most important method-ologies applied for glass, quartz, polymers and metals microreactors manufacture and fortheir coating, analyzing the advantages and drawbacks of every procedure. Furthermore, anoutline of the novel insights based on additive manufacturing techniques are described.
