Description
1.one.
Изобретение относитс к способу поттучени хлористого агаомини и может быть использовано в цветной металлургии,The invention relates to a process for the treatment of agaomin chloride and can be used in non-ferrous metallurgy.
Известен способ получени хлористого алюмини , зак;цочающийс в том, что на первой стадии т желое мае по при 75О-110О С подвергают крекингу на окиси алюмини , а на второй стадии окись агпомини , покрытую углеродом, хлорируют в псевдоожиженном слое при 450-8ОО С 1. Недостатком этого способа вл етс необходимость проведени процесса в две стадии, трудность достижени равномерного осаждени углерода на окиси алюмини .A method of producing aluminum chloride is known; it is found that in the first stage, heavy may be cracked on alumina at 75 ° -10 ° C, and carbon-coated aggominy oxide in the second stage is chlorinated in a fluidized bed at 450-8OO. 1. The disadvantage of this method is the need to carry out the process in two stages, the difficulty of achieving uniform carbon deposition on alumina.
Известен также способ получени хлористого алюмини путем обработки сырь , содержащего окись алюмини , хлором и окисью углерода при 4бО-650°С 2, Основным недостагком этого способа вл етс большслг дпительность процесса (пор дка 20 ч),There is also known a method for producing aluminum chloride by treating a raw material containing alumina, chlorine and carbon monoxide at 4 ° -650 ° C 2. The main disadvantage of this method is the large process (about 20 hours),
С целью интенсификации процесса получени хлористого алюмини описывают способ, заключающийс в том, что сырье, содержащее активированную окись алюмини о удельной поверхностью м /г, содержащуюIn order to intensify the process of obtaining aluminum chloride, a method is described that consists in that the raw material containing activated alumina with a specific surface area of m / g containing
0,5-10% воды, обрабатывают хлором и окисью углерода при нагревании, причем в качестве сырь используют боксит и процесс ведут при 4ОО-8ОО°С.0.5-10% of water is treated with chlorine and carbon monoxide when heated, and bauxite is used as a raw material and the process is carried out at 4OO-8OO ° C.
Отличительным признаком способа вл етс использование в качестве сырь активированной окиси алюмини с удельной поверхностью 1О-45О м /г, содержащей О,Г). воды, а также использований боксита и гфоведение процесса при 4ОО-8ОО С, Это позвол ет значительно интедаифишфовать процесс , длительность которого сокращаетс до 4О мин.A distinctive feature of the method is the use of activated alumina as a raw material with a specific surface of 1O-45O m / g, containing O, D). water, as well as the use of bauxite and hydrofusion of the process at 4OO-8OO C. This allows a significantly integrated process, the duration of which is reduced to 4 ° min.
Пример. 13О-135 мг боксита из Сьерра-Леона нагревают в потоке азота, подаваемого в количестве 4 л/ч в течение 30 мин до посто шюй температуры реакции, котора находитс в диапазоне 4ОО-вОО С, При 22О-24О С начинают термическое разложение боксита в высокоактивный боксит с большой внутрешюй поверхнсх;тъю, составл ющей 15О-25О м /г. Через ЗО мин отключают подачу азота и смесью хлорида и окиси углерода в соотношении 1:1 (по 2 п/ч) обрабатывают боксит, го ггржпщий активировшгную окись-алюмини . XnopupoBainie BejiyT .в течение 4О мин и достигают стеь .iH превращени свьице 9О%,Example. 13 O-135 mg of bauxite from Sierra Leone is heated in a stream of nitrogen supplied in an amount of 4 l / h for 30 minutes to a constant reaction temperature, which is in the range 4OO-HEO C. At 22 O-24 O C, thermal decomposition of bauxite is started. highly active bauxite with a large internal surface; with a diameter of 15 O-25 O m / g. After 30 minutes, the supply of nitrogen is shut off and a mixture of chloride and carbon monoxide in a ratio of 1: 1 (2 p / h each) is treated with bauxite, which is activated activated alumina. XnopupoBainie BejiyT. Within 4 minutes and reach the .iH stage of the conversion 9O%,
