Sorbent from aluminium oxide may adsorb nitrogen and sulphur oxides and be regenerated heating in 600-650 degrees Celsius; it is produced by including aluminium an oxide stabilisation agent into the sorbent. The precipitation moment is the most proper way to add aluminium oxide. Afterwards a prepared precipitated powder suspension, made of fine and poured out in drops in order to let a form of stabilised spheroid aluminium oxide elements. In order to get a stabilised sorbent, these elements are soaked with alkaline or earth metals. Stabilisers of the aluminium oxide are of silicon dioxide, lanthanum oxide, other oxides of rare earth metals, titanium oxide, zirconium dioxide and earth metals. |
