The unique properties and selectivities of zeolites can provide effective solutions for environmental pollution by minimizing the production of pollutants and by secondary treatment of the effluents produced.
Many of the gains made by the current generation of environmental technologies are being offset by the growth of industrialized populations. Consequently, new and creative pollution prevention and abatement methods are under investigation.
Several areas in which zeolites show strong environmental potential are:
- Reduction of atmospheric NOx
- Reduction of atmospheric VOC's (including automotive cold start)
- Process improvements in the chemical industry
Zeolyst International can provide zeolite products for the following:
- NOx Reduction Catalysts
- Custom Powders and Catalysts
As vehicles, their engines, and their fuels are redesigned to reduce the creation of pollutants, so too are zeolites being designed and employed to handle the new concentrations, combinations, and conditions of combustion products. One example involves the use of efficient, oxygen-rich, lean-burn diesel engines, which produce less CO2, a greenhouse gas. Metal-exchanged zeolite catalysts have been employed on these vehicles as a less costly and more effective option for NOx removal than the three-way catalytic converter.
Another emerging zeolite technology is lean NOx, a catalytic process that uses hydrocarbons such as methane and higher hydrocarbons as the reductant, making it practical for automotive and other mobile sources.
Zeolyst International is always open to partner with you to help develop a new custom catalyst for your application.
