Project

Exploiting ultrasound resonance to intensify photochemical reactors

Small-scale flow reactors for photochemistry support the shift in

chemical manufacture towards green and sustainable processes

based on renewable energy sources. However, the industrial

application of these small-scale flow reactors is significantly limited

by their currently achieved throughput and productivity. This project

aims to overcome these productivity limitations by exploiting the

synergistic effect of ultrasound on intensified photochemical reactors.

Specifically, we will gain a fundamental understanding of the

underlying ultrasound physics and their interplay with the reactor

geometry and fluids. We will exploit this fundamental understanding

to controllably excite ultrasound resonance modes to overcome

species and photon transport limitations in rationally designed

intensified reactors. We will increase light utilization and mass

transfer in two-phase photochemical reactors by inducing the gasliquid

atomization phenomenon (i.e. to nebulize liquid droplets from

the liquid slug into the illuminated gas bubble) via ultrasound

resonance. Hence, this project will provide fundamental

understanding of ultrasound resonance modes leading to innovative

and intensified photochemical reactors promoting green and

sustainable chemistry.
