PROCESS FOR SOLIDIFYING SURFACES OF GRANULAR ADSORBENTS |
摘要 |
A process for consolidating the surface of a granular adsorbent, wherein a water-containing adsorbent, which has taken up 25-70% by weight of the maximum possible amount of water, is heated to a temperature at which the water taken up evaporates, and is at the same time treated with an aqueous dispersion of a self-crosslinking copolymer, and the adsorbent thus coated is heated to a temperature at which the copolymer crosslinks. The coated adsorbent has virtually the same adsorption and desorption properties as the untreated adsorbent, but in contrast exhibits substantially improved abrasion resistance. |
