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.

BASF introduces new sulphuric acid catalyst

  • Unique shape leads to 30 percent greater catalytic surface area
  • New sulphuric acid catalyst O4-115 Quattro in operation at first reference plant already for one year
  • Proven performance improvement for sulphuric acid producers

BASF has introduced the new sulphuric acid catalyst O4-115 Quattro into the market. The new, cesium-based catalyst is unique due to its geometrical shape – a combination of four strands – leading to a 30 percent greater catalytic surface area compared to conventional sulphuric acid catalysts. For sulphuric acid producers, this translates into higher conversion in the catalyst bed, reduction of SO2 emissions, and improved performance in plants with limited catalyst volumes. Additionally, the O4-115 Quattro features enhanced physical and mechanical properties. Due to its improved catalyst hardness, which is reflected in a lower sieving loss, this new catalyst offers long-term stability and cost-efficient operation.

A reference plant operated by Domo Caproleuna GmbH has been using the new sulphuric acid catalyst O4-115 Quattro since 2016. With the new catalyst, the plant has seen an increase of the SO2 conversion and a simultaneous capacity increase. Ulf Müller, Domo Caproleuna’s plant manager, is pleased with the BASF Quattro catalyst performance: “The right catalyst is a crucial factor for successfully operating a sulphuric acid production plant. Since we have been using the O4-115 Quattro catalyst, we are able to operate our plant in a much more efficient way.”

BASF is one of the leading manufacturers of sulphuric acid catalysts worldwide, leveraging its own sulphuric acid production expertise. The company operates four sulphuric acid plants at its headquarters in Ludwigshafen, Germany where the latest catalyst technologies are used.

“For the new development of catalysts, in-house sulphuric acid production is a huge advantage because we can gain important insights on the performance and long-term stability of the catalysts, and our customers can directly benefit from these findings,” said Detlef Ruff, Senior Vice President, BASF Process Catalysts. “In addition, we are continuously investing in sulphuric acid catalyst research to help our customers be even more successful. In 2016, we launched a new catalyst test facility, and the sulphuric acid catalyst O4-115 Quattro is the first of many new developments that will emerge from it.”
