Abstract

Изобретение относитс  к химической промышленности и может быть использовано при получении безводного хлорида алюмини , используемого дл  производства металлического алюмини . Цель изобретени  - повышение производительности процесса. Дл  этого алюминатный раствор подвергают карбонизации при 30-60°С в течение 1,5-3,0 ч. При этом получают смесь байерита и гиббсита в соотношении /9-4/:1, которую прокаливают при температуре 700-900°С до получени  соотношени  γ H=AL 2O 3:γ B=AL 2O 3 = /6-3/:1, где γ H - низкотемпературна  модификаци , γ B - высокотемпературна  модификаци . Полученный оксид подвергают хлорированию. Данный способ позвол ет повысить производительность процесса с 20 до 31-35 кг/ч ALCL 3. 1 табл.The invention relates to the chemical industry and can be used in the preparation of anhydrous aluminum chloride used for the production of aluminum metal. The purpose of the invention is to increase the productivity of the process. For this, the aluminate solution is carbonized at 30-60 ° C for 1.5-3.0 hours. A mixture of bayerite and gibbsite is obtained in a ratio of / 9-4 /: 1, which is calcined at a temperature of 700-900 ° C to obtaining the ratio γ H = AL 2 O 3: γ B = AL 2 O 3 = / 6-3 /: 1, where γ H is a low-temperature modification, γ B is a high-temperature modification. The resulting oxide is subjected to chlorination. This method allows to increase the productivity of the process from 20 to 31-35 kg / h of ALCL 3. Table 1.
