Enzyme Immobilization in Wall-Coated Flow Microreactors
2020Flow microreactors are emergent engineering tools for the development of continuous biocatalytic transformations. Exploiting enzymes in continuous mode requires their retention for multiple rounds of conversions. To achieve this goal, immobilizing the enzymes on microchannel walls is a promising approach.

Coking in pulse and flow microreactors
Chemical Engineering Science, 1992Abstract A relation is obtained for coke deposition in pulse microreactors. The relation has three parameters: an initiation rate constant, a chain-growth rate constant, and an asymptotic deposition amount. The relation can be easily extended to apply to coke deposition in continuous-flow reactors.

Continuous Flow Enzyme-Catalyzed Polymerization in a Microreactor
Journal of the American Chemical Society, 2011Enzymes immobilized on solid supports are increasingly used for greener, more sustainable chemical transformation processes. Here, we used microreactors to study enzyme-catalyzed ring-opening polymerization of ε-caprolactone to polycaprolactone. A novel microreactor design enabled us to perform these heterogeneous reactions in continuous mode, in ...

Green and Sustainable Chemical Synthesis Using Flow Microreactors
ChemSusChem, 2010AbstractSeveral features that allow flow microreactors contribute to green and sustainable chemical synthesis are presented: (1) For extremely fast reactions, kinetics often cannot be used because of the lack of homogeneity of the reaction environment when they are conducted in batch macroreactors. Better controllability, by virtue of fast mixing based

Propane combustion in non-adiabatic microreactors: 2. Flow configuration in posted microreactors
Chemical Engineering Science, 2011Abstract The aim of this paper is to analyze cross-flow operation in a microreactor with posted catalytic inserts for Pt-catalyzed propane combustion under fuel-lean conditions. The insert consists of 150 posts arranged in-line in six rows. The posts are static pillar-like structures in the flow channel, which act as static mixers and provide higher ...

Pauson–Khand Reactions in a Photochemical Flow Microreactor
Organic Letters, 2013Pauson-Khand reactions were achieved at ambient temperature without any additive using a photochemical flow microreactor. The efficiency of the reaction was better than that in a conventional batch reactor, and the reaction could be operated continuously for 1 h.
