Photocatalytic Oxidation of Methanol Using Silica-Titania Composites in a Packed-Bed Reactor.

The article reports on the development of a photocatalytic packed-bed reactor for the oxidation of methanol, which is the key component of high volume volatile organic gases emitted from pulp and paper mills. Bench-scale studies were performed using an annular reactor packed with silica-titania composite pellets, to optimize methanol removal and reduce the formation of by-products such as formaldehyde.
