Protecting the air we breathe from harmful emissions through innovation. BASF leverages unsurpassed expertise in the development of emission control technologies for a wide range of market applications. Did you know there can be 5x more air pollution inside your house than outside of it? Indoor Air Quality (IAQ) refers to the air quality within and around buildings and structures, especially as it relates to the health and comfort of building occupants. Understanding and controlling common pollutants indoors can help reduce risk of indoor health concerns. BASF offers the widest portfolio of adsorbent technologies for a broad spectrum of applications in industries such as refining, petrochemical, chemical, and gas processing. The BASF portfolio includes proprietary alumina, silica, alumino-silica gels and a broad line of base metal oxide guard bed materials, including the PuriStar family. At BASF, our Fluid Catalytic Cracking (FCC) catalyst and additive offerings together with our expert technical services build the right solution to create value within any unit’s constraints. The increasing demand for energy and resources is what drives us to develop more sustainable solutions, while addressing the need for energy efficiency and conservation. We partner with those who share our commitment to a healthier, more natural and more affordable future for energy and resources. We are constantly improving the quality and reliability of our products, and strive for even greater efficiency and productivity. BASF Natural Gas experts have a diverse portfolio of products to custom design a solution and help you meet your Natural Gas treatment needs. BASF has been serving the natural gas treatment market for over 60 years. With more than 150 years of experience in metal sourcing, trading, and hedging, we’ve built tangible results for our industrial customers. With more than 100 years of experience in recycling materials, BASF’s end-to-end recycling program is known and trusted around the globe. As a leader in precious-metal thermocouples for many years, BASF recently applied its technological expertise to optical-based temperature measurement. BASF Sorbead® Air adsorbents are alumino silicate gels in the form of hard, spherical beads. They are essential in removing water from compressed air so that the efficiency of chemical processes is not compromised. Sorbead® Air is the most energy saving and environmentally friendly adsorbent available for the air compression industry. Innovative, step-change technology with dual-purpose performance: removal of heavy hydrocarbons and water to cryogenic specifications in a single unit.

Our Innovative Solutions

Protecting the atmosphere from harmful emissions is the focus of all innovative solutions. New engine technologies, tightening emission regulations and fluctuating precious metals prices create emissions control challenges. We help make our customers more successful with innovative, cost-effective solutions to meet the toughest emissions control regulations.

Three-Way Conversion Catalyst (TWC)

TWC technology for gasoline engines. A leader in clean air technology, BASF has unsurpassed expertise in the development of catalysts for a wide range of applications that protect the air we breathe. Catalyst expertise enabled us to pioneer the development of the first catalytic converters for automobiles, which appeared on 1975-model cars. A year later, we introduced a major innovation — the modern, Three-Way Conversion catalyst (TWC), which today is capable of destroying over 90% of hydrocarbons (HC), carbon monoxide (CO) and oxides of nitrogen (NOx) produced by gasoline engines. In fact, it would take over 100 of todays cars to equal the pollution from one pre-1974 car. We were awarded the National Medal of Technology and the United Nations Award of the Decade, for the development of the first three-way automotive emissions control catalyst. Arguably the most important pollution abatement device ever invented, the catalytic converter now is a key component of most new cars around the world. Today, BASF continues to lead the way in the development and commercialization of advanced emissions catalysts. We work closely with our customers to manage the precious metal content in the catalysts. Our focus is on helping our automotive customers cost-effectively comply with tightening environmental regulations around the world.

This state-of-the-art platform technology uses BASF's patented, segregated washcoat technology, which precisely places the precious metals within the washcoat, resulting in several important benefits:

Optimal use of precious metals

Lower cost and higher effectiveness

Higher conversions of CO, HC and nitrogen oxides (NOx) over a wide range of conditions

BASF's TWC catalysts:

  • Have a lower light-off temperature
  • Offer high temperature stability enabling the catalyst to be moved closer to the manifold
  • Minimize hydrogen sulfide (H2S) emissions without using nickel
  • Have outstanding resistance to lead
  • Have a stable oxygen storage function to help original equipment manufacturers (OEMs) meet On-Board Diagnostics II (OBDII) requirements

Four-Way Conversion Catalyst (FWC)

The innovative single component FWC (Four-Way Conversion) catalyst can remove Particulate Matter (PM), as well as CO (Carbon Monoxide), HC (Hydrocarbons) and NOx (Nitrogen Oxides) from gasoline-engine exhaust. Upcoming Euro 6 and US Tier 3 regulations will enforce, besides the well-known limits for HC, CO and NOx, tighter control of PM emissions from gasoline-engine powered vehicles. BASF has developed innovative FWC catalyst technologies that can be applied in a system, together with a standard TWC, as a CC (Close Couple) or UF (Under-Floor) or even as a FWC-only device for a fully integrated system. The innovative FWC catalyst combines the functionality of a TWC catalyst with a filter to remove all four pollutants with just one component.

The benefits include:

Smart solutions to lower backpressure impact

Potential to reduce package design

Ensure particulate emissions below tight regulation limits

Reduction in system complexity, tooling and overall system cost

LGC Lean GDI (Gasoline Direct Injection) Catalyst

The patented BASF Lean GDI (Gasoline Direct Injection) Catalyst technology provides the additional NOx (nitrogen oxides) removal required from the exhaust of GDI engines. These engines use lean combustion (excess of air) to deliver improved fuel economy. However NOx exhaust emissions can increase and are a challenge to remove under these lean operating conditions. The Lean GDI catalyst is designed to operate under lean conditions and can be placed after the TWC catalyst to provide additional NOx conversion.

The benefits include:

Exceptionally high thermal stability

High NOx removal activity at high temperature

High NOx storage capacity

High NOx reduction efficiency
