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.

Sulfuric Acid

BASF designs catalysts for maximum performance. Since 1913, we have run production plants with the lowest levels of sulfur dioxide (SO2) emissions in the world. That’s because the large surface area of our sulfuric acid catalysts delivers an unrivaled SO2 emission profile.

To our customers, that means effortless regulatory compliance, no additional emission reduction costs, higher conversion and bigger profits. These results last. Because of their exceptional physical stability, our catalysts offer a longer lifetime, energy savings and minimal downtime risks.

At BASF, all of that comes with total service dedication, reliable customer support backed by the inventor of sulfuric acid catalysts, and decades of experience.

Patents: Never Stop Inventing

In 1913, the first patent on the vanadium-based catalyst was granted to BASF. Invented by BASF, the vanadium-based catalyst is still the chemical foundation of all sulfuric acid catalysts on the market.

That’s how the new O4-115 Quattro was born. The latest addition to our catalyst family features a 30 percent higher surface area and improved pore accessibility to boost performance, reduce emissions and further increase your plant capacity. This new shape is patented by BASF.


BASF catalysts are proven in our plants and designed to enhance yours. Our sulfuric acid production plants have had the lowest SO2 emissions in the world since 1913, making them ideal for regulatory compliance and cost savings. Work with us to get the full benefit of almost a century’s worth of experience. Our oxidation catalysts are optimized for manufacturers that produce:

  • Fertilizers
  • Chemicals
  • Detergents
  • Dyes
  • Pigments
  • Pharmaceuticals
  • Steel
  • In Metallurgical Processes
