Trust BASF absorbents for olefin purification

BASF is a leading supplier of adsorbents to a wide range of industries and this for more than 50 years. We help companies meet and exceed demanding economic, quality, environmental, and government standards with tailored solutions. A special focus lies with those industries that generate, recover, and use olefins, and for which BASF offers products under the title of Olefin Purification.


BASF offers:

  • Highly-effective removal of a wide range of contaminants from olefin-containing streams
  • Complete system solutions for treatment of olefin-containing streams from catalytic crackers (FCC, DCC, CPP) and acetylene producing units
  • Complete system solutions for treatment of olefins used in polyolefin and cumene units
  • Long lifetime and easy operability
  • Physical hardness and durability
  • Outstanding global technical support and distribution

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

Selexsorb® Activated Aluminas

PuriStar® and ProsorbTM Metal Oxide-based products


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


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 +.
