Summary
A new procedure effectively scales up photoreactors for advanced oxidation processes (AOPs) using lab data. This method accurately predicts performance in large-scale reactors, validated by experimental results for formic acid decomposition.
Area of Science:
- Chemical Engineering
- Environmental Science
- Photocatalysis
Background:
- Advanced Oxidation Processes (AOPs) are crucial for water treatment.
- Scaling up photoreactors from laboratory to industrial scale presents significant challenges.
- Accurate kinetic modeling is essential for efficient photoreactor design.
Purpose of the Study:
- To develop and validate a procedure for scaling up photoreactors used in AOPs.
- To apply the developed procedure to the decomposition of formic acid using UV/H2O2.
- To bridge the gap between laboratory-scale experiments and large-scale reactor predictions.
Main Methods:
- Laboratory experiments in a small batch reactor with recycling.
- Kinetic parameter estimation using radiation and mass balances.
- Non-linear parameter estimation to derive model kinetic constants.
- Modeling of a large-scale continuous tubular flow photoreactor (2m length, 12L volume).
Main Results:
- Kinetic parameters for formic acid decomposition were successfully obtained.
- The scale-up procedure accurately predicted performance in the large-scale reactor.
- Experimental data from the large-scale apparatus showed good agreement with theoretical predictions.
Conclusions:
