Batch reactors or flow reactors are used to test the oxidation property of catalysts and catalytic membranes. Basic properties and operation conditions are tested in a laboratory scale reactors. Combinatorial approach (high through put method) is a strong tool to sort the catalysts and can be used in the photo-catalyst development. Laboratory scale test rig can treat e.g. 1-2L of liquid in one test.
A catalytic membrane reactor in a pilot scale has been demonstrated by Due Miljø through the EU-project WaterCatox and is under operation at SINTEF. A similar configuration can be used for a photo-catalytic membrane reactor in a pilot scale.
