Patent ID: 7695546

Claim:
A process for adsorbing and/or absorbing organic and/or inorganic substances from a liquid or gaseous phase comprising contacting said liquid or gaseous phase with an adsorbent which is a spherical granular adsorbent for organic compounds consisting of granules which contain 20 to 99.9 wt. % of filler particles of silica and rubber as a binder, said adsorbent having been made by a process of mixing at least one binder which is rubber with at least one filler particle which is silica in a granulator having a spiked shaft, by injecting the binder by means of at least one nozzle into said granulator in at least one location and granulating resulting mixture, whereby the filler particles are incorporated into the surface of the binder such that the resulting adsorbent does not stick together, said mixing taking place at a temperature of from 20° to 140° C., with a rotational speed of the granulator being from 100 to 1500 rpm, and where the circumferential speed of spike tips in said spiked shaft is 1 to 30 meters/sec.
