Mobile Emissions Catalysts Overview

New engine technologies, tightening emission regulations and fluctuating precious metals prices create emissions control challenges. BASF helps make customers more successful with innovative, cost-effective solutions to meet the toughest emissions control regulations.

BASF Mobile Emissions Catalysts: Driving Solutions for a Sustainable Future

Since its inception, BASF’s three-way catalyst technology has destroyed over 1 billion tons of HC and NOx and CO before they ever reached the atmosphere. BASF continues to lead the way in the development and commercialization of advanced emissions catalysts for both gasoline and diesel-powered vehicles.

PremAir® Direct Ozone Reduction

PremAir® is a patented catalyst coating from BASF that transforms ground level ozone, the main component of smog, into oxygen. As air flows over a vehicle's coated radiator, PremAir® catalyzes the reaction that converts ozone into oxygen.

How does the three-way catalytic converter work?

The widespread introduction of such catalytic converter systems in North America (starting in 1976) and Europe (1986) resulted in a marked decrease in metropolitan air pollution from harmful tailpipe emissions despite a growing population of vehicles. This device was able to catalyze the conversion of the three main pollutants (unburned hydrocarbons, carbon monoxide and nitrogen oxides) simultaneously.

FWC™ Four-Way Conversion Catalyst - How Does it Work?

The innovative FWC™ catalyst combines the functionality of a TWC catalyst with a filter to remove all four pollutants from gasoline-engine exhaust, with just one component. This can help automakers meet strict new emissions regulations including Euro 6.

EMPRO™ LNT & CSF.4 emissions control system for Euro 6c

BASF created the innovative LNT+CSF.4 emission control system for diesel engines to meet the Euro 6c regulations. The system combines the features of the Lean NOx Trap (LNT) and a multifunctional catalyzed soot filter (CSF.4) that removes Particulate Matter (PM) as well as Carbon Monoxide (CO), Hydrocarbons (HC) and NOx from the exhaust. This system also eliminates one catalytic component from the existing solution resulting in lower system weight, space and complexity.

When traffic and clean air go together, it's because at BASF, we create chemistry.
