Environmentally Friendly Catalysts

Using the HYDECAT process

The HYDECAT process was first developed for the decomposition of waste hypochlorite solutions arising from the manufacture of hypochlorite bleach.

The HYDECAT equation

2NaOCl

2NaCl + O2

As can be seen from the equation above, the catalytic decomposition releases oxygen. It was realised that this oxygen could be used to oxidise unwanted impurities in environmental contexts. So the same chemistry that had been developed for the HYDECAT process was adapted for use in other areas.

Putting HYDECAT to use

Under the name Odorgard the catalytic process was introduced to remove smells in a range of industries including meat rendering, sewage water treatment, food and spice processing and leather tanning.

The environmental capability of the process has been further extended to treat liquid effluents under the names of Accent and Accolade. These have been particularly successful in dealing with impurities that are not easily treated by other means because, for example, they are biotoxic or non-biodegradable.

So chemical catalyst technology originally designed for one purpose has provided important benefits in some totally new areas.
