ABSTRACT:
A hybrid adsorbent including particles of porous alumina having deposited thereon an ultrathin layer of carbon atoms which is essentially monomolecular. The carbon layer is produced by cracking a suitable hydrocarbon, preferably a gas, in contact with a hot turbulent fluidized bed of alumina particles. The hybrid adsorbent has the unique property of adsorbing more organic impurities than an equivalent weight of active carbon, and also oxalate ions which are not ordinarily adsorbed by carbon.
