Widest portfolio of adsorbent technologies for a broad spectrum of applications. Catalytic converters for aircraft cabins and fuel inerting. Cathode materials, e-mobility, next-generation technology solutions. Air cleaners that help to improve indoor air quality. Solutions for the most challenging applications. BASF maintains significant diesel research and development facilities around the world. These facilities are being used to develop the technologies needed to meet the extremely low emission levels called for in new emissions regulations. As the global leader in mobile emissions catalysts, BASF has developed a number of specialized catalyst technologies. BASF offers a "full loop" of precious metals products & services. Catalysts for chemical, petrochemical, and refining industries. We offer precious metals supply and full-loop management services, including refining to recover precious metals from spent catalysts. The development of fuels and chemicals based on biological feedstocks is critical to a sustainable future and BASF is proud to provide the catalysts to support this industry. BASF has established itself as a front-runner in this field by becoming the global market leader for sodium methylate, the homogeneous catalyst used for biodiesel production. BASF catalyst technologies play a crucial role in the manufacture of a wide range of fine and specialty chemical products including flavor and fragrances, herbicides and pesticides, resins, pigments and dyestuffs, pharmaceuticals, and plastic and rubber additives. Chemistry plays an important role in the transformation of vegetable oils to products for our daily life. Catalysts are an indispensable tool to make this transformation possible. BASF offers more than 125 years of experience with oxidation catalysts. Each percent of catalyst selectivity advantage creates additional value and reduces COx emission. Solutions for power plants, process industries and more. BASF Catalysts has long been a leader in the development of highly active, robust and selective catalysts and related technologies for the destruction of volatile organic compounds (VOC). Thermocouples, pyrometers - insights for higher yields. Our contact temperature probes include high temperature thermocouples, platinum thermocouples, noble metal thermocouples, thermocouples for the glass industry, profile and spike thermocouples for diffusion furnaces, high temperature industrial thermocouples, furnace thermocouples, and high temperature thermocouple wire and cable. A specialty of BASF for many years is the glass thermocouple. We have grown with the industry and, as glass technology requirements have expanded and changed over the years. Offering excellent accuracy, resolution, repeatability, and stability, EXACTUS® optical pyrometer technology provides significant performance advantages in non-contact temperature measurement in a practical, rugged and user-friendly design.

Sulfuric Acid Catalysts

Since 1913 BASF runs the lowest SO2-emission sulfuric acid production plants worldwide. We design our catalysts for maximum outcomes. That starts with the unrivaled SO2-emission performance they can deliver because of their large surface area. 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, deliver energy savings, and minizime downtime risks. At BASF, all of that comes with total service dedication, reliable customer support backed by the inventor of the sulfuric acid catalysts, and decades of experience.

BASF offers full systems design for:

  • Performance reliability from planning through all phases of plant operation
  • Simulations of plant operations
  • Converter design calculations
  • Highest conversion requirements
  • Capital investment optimization
  • SO2 emission reduction
  • Environmental protection maximization
