Overcoming mass and photon transfer limitations in a scalable reactor: Oxidation in an aerosol photoreactor

The use of microflow reactors enabled dramatic improvements in the apparent rates photochemical reactions. However, scaling-up photomicroreactors remains a challenge due to difficulties distributing light and flow all units photomicroreactors. In this work, mass photon transfer limitations an easily scalable micro-structured reactor, aerosol photoreactor, was studied. reactor concept, each droplet works as microreactor. nature interaction enables good distribution droplets. A singlet oxygen mediated photosulfoxidation reaction utilized model assess performance. were proven be overcome photoreactor. rate constant calculated 0.12 s−1. simple solution convection–diffusion equation for presented check reactors. Sauter mean diameters droplets at different pressures varied between 7 8 µm. photoreactor these diameters. addition, highest volumetric coefficient (kLa) 1.2 s−1, which same order magnitude compared other intensified photoreactors such Corning Advanced Flow ReactorsTM or gas–liquid discussion on increasing throughput further is presented. This work paves way efficient industrial use.
