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.

Styrene Catalysts

The world’s highest stability by the inventor of styrene catalysts

For styrene producers requiring highest operational stability & productivity,

StyroStar® offers superior product stability from the original inventor of styrene industrial production and styrene catalysts (1929) as evidenced in the world’s largest reference list including BASF’s own styrene production.

BASF StyroStar® styrene catalysts are used in a wide range of 2 and 3 reactor adiabatic dehydrogenation technology designs. These technologies combine superheated steam with ethyl benzene to produce styrene with minimum formation of by-products. BASF styrene catalysts are suitable for a wide range of plant designs and operating conditions including 3-stage applications such as the UOP / Lummus SMART technology.

BASF Styrene Catalysts Provide:

  • Outstanding activity and selectivity
  • Excellent stability at low steam to oil (S/O) ratios
  • Robust and durable
  • Exceptionally low monthly decline rate
  • Low by-products formation, e.g. Phenylacetylene, Toluene, Alpha Methyl Styrene, and heavies.
