Catalyst for chlorinated VOCs competes with incineration

German chemical manufacturer Hoechst has developed a catalytic oxidation system which is claimed to be particularly effective for the destruction of chlorinated volatile organic compounds (VOCs). The technology is claimed to be cheaper and more effective than incineration.

Demand for efficient methods of capturing or destroying VOCs is set to grow strongly in the UK over the next few years as emission controls are implemented under the Environmental Protection Act 1990. Hoechst's innovation joins the growing number of technologies competing in this market.

Destruction of VOCs occurs over two catalyst beds. The first, aluminium oxide catalyst breaks down most of the chlorinated VOCs. Remaining hydrocarbons a
