Control Exhaust Emissions

Pollutants from tailpipe emissions include CO, NOx, hydrocarbons, and particulate matter (PM). Tier II standards, which will be fully phased in by 2009, call for a 90% reduction in NOx and PM from the earlier Tier I standards. Future environmental regulation will be tougher, and may even cover CO2 emissions. Accelrys technology provides a means to improve catalyst efficiency through in silico experimentation, and even provides way explore new reaction mechanisms such as HC-SCR (hydrocarbon selective catalytic reduction). Accelrys solutions can help you study:

• Three-way catalysts
• SCR
• Effect of poisons (sulfur)
• Efficiency of reduced precious metal content
