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.

Olefin Purification products from BASF are offered under the following trade names:

Selexsorb® Activated Aluminas

PuriStar® and ProsorbTM Metal Oxide-based products

Besides offering products for olefin purification, BASF also offers a wide range of products for oxygen removal or removal with the help of oxygen. These products are referred to as DeOxo catalysts.

Selexsorb®

Selexsorb CD is custom-formulated to provide optimum adsorption of a number of polar compounds including: water, oxygenated hydrocarbons (alcohols, aldehydes, ketones, ethers, peroxides), mercaptans, sulfides and nitrogen-based molecules (ammonia, amines, nitriles).

PuriStar®

PuriStar R3-16 is a high-efficiency CuZn catalyst which is tailor-made for the purification of polymer-grade ethylene.

Prosorb

Prosorb N, used as sulfur guard beds for naphtha reformers and isomerization units, is a next generation, nickel-based adsorbent which provides significant performance improvement for removal of trace levels of various sulfur species.

Applications for Adsorbents for Olefin Purification

Olefin purification adsorbents can be found in various areas such as refineries for ethylene recovery and propylene recovery, steam crackers for cracked gas purification, and down to the consumer level for EPDM plants, butanol plants, among others. A graphic showing the different applications and the typical location of BASF adsorbents used is provided. For enlarging the graphic, please click on the +.
