PROCESS FOR SOLIDIFYING SURFACES OF GRANULAR ADSORBENTS

摘要

A process for consolidating the surface of a granular adsorbent, wherein thermoplastic crosslinkable bonding fibers are applied from aqueous suspension, the water taken up by the adsorbent is evaporated off and the bonding fibers adhering to the surface of the adsorbent are crosslinked by heating. The adsorbent thus treated has virtually the same adsorption and desorption properties as the untreated adsorbent, but exhibits substantially improved abrasion resistance.
