Contributing to climate and

ENVIRONMENTAL PROTECTION IN THREE WAYS

By mitigating the greenhouse effect, helping to preserve the ozone layer, and reducing atmospheric pollution with other, health and climate damaging nitrogen oxides, the EnviNOx® process contributes to climate and environmental protection. The catalyst EnviCat®N2O is a central component of the innovative process.

Challenge

REDUCING HARMFUL EMISSIONS – THE CATALYST ENVICAT®N2O AND ENVINOX® REMOVE NITROUS OXIDE

The signs of climate change can no longer be ignored. While carbon dioxide is a major contributor to the greenhouse effect, nitrous oxide – commonly known as laughing gas – is the third most damaging climate gas after methane and is responsible for about 6% of anthropogenic climate effects. One unit of nitrous oxide is about 300 times more climate damaging than the same amount of CO2. Nitrous oxide results mainly from the industrial production of nitric acid used in fertilizer manufacture and other processes.

Solution

An innovative catalyst in an ingenious process

The Clariant catalyst EnviCat® N2O used in the EnviNOx® process, developed by ThyssenKrupp Uhde GmbH, removes nearly all of the nitrous oxide from the tail gas of nitric acid plants and converts it in two stages to the harmless substances oxygen, nitrogen and water. At the heart of the process is the highly active catalyst EnviCat® N2O consisting of porous, crystalline zeolites.
