Sorbead WS
Water-resistant adsorbent

BASF Sorbead WS water resistant silica gel adsorbents have high capacity and protect other adsorbents and catalysts from water vapor in a broad range of applications.
The BASF Sorbead line of highly efficient adsorbents is an alumino- silicate gel formed into hard, spherical beads ¨C having a high resistance to crushing and a low attrition rate. Sorbead adsorbents have a longer life than most other adsorbents and can reduce opera- ting costs in most applications.

Sorbead WS is the only 100% water-resistant adsorbent with a high adsorption capacity. It is frequently used as a protective layer in combination with Sorbead

R, Sorbead H, Sorbead Plus or other adsorbents such as mole-cular sieves, activated alumina, activated carbons and catalysts in order to increase the reliability of the system. The high capacity ofSorbead WS enables it to be used on a stand-alone basis as well.

With its high resistance against hydrothermal aging and low regeneration temperature, BASF Sorbead WS is ideal for applications where adsorbent regeneration with humid gas occurs (e.g. heat-of-compression, blower-purge air dryers and air separation plants).
