Abstract

Procedeu de obtinere a oxidului de aluminiu si a acidului clorhidric, prin descompunerea clorurii de aluminiu hidratate într-un reactor cu încalzire indirecta si calcinarea si descompunerea cantitatilor reziduale de clorura de aluminiu într-un cuptortubular rotativ încalzit direct cu racirea oxidului de aluminiu format într-un cuptor rotativ tubular, cu racirea oxidului de aluminiu, format într-un tub rotativ cu preîncalzirea simultana a gazelor cu continut de oxigen caracterizat prin aceea ca, în scopul obtinerii de acid clorhidric gazos de mare concentratie, 70.....95% din clorura de aluminiu se descompune în zona încalzita în mod indirect materialul astfel descompus se introduce în zona de calcinare a oxidului de aluminiu.
