Reducing a climate killer - 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 happy gas or 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 that is 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. |
