Description
Обычно дл извлечени хлористого алюмини из отходов крэкинга нефти примен ют воду, что влечет за соб&й увеличение зольности нефт ного кокса, так как при крэкинге часть хлора из его соединени с алюминием улетучиваетс в виде сол ной кислоты.Typically, water is used to extract aluminum chloride from waste oil cracking, which results in a consistent increase in the ash content of petroleum coke, since in cracking some of the chlorine from its compound with aluminum evaporates as hydrochloric acid.
Предлагаемый способ переработки отходов имеет целью устранить-указанный недостаток и получить из отх-ода два ценных продукта, нужных дл производства металлического алюмини , а именно: чистую окись алюмини и нефт ной кокс, а также сол ную кислоту, котора может найти применение вместо серной кислоты дл пол чени фосфористых удобрений.The proposed waste treatment method aims to eliminate this drawback and to obtain from waste products two valuable products needed for the production of metallic aluminum, namely, pure alumina and petroleum coke, as well as hydrochloric acid, which can be used instead of sulfuric acid. to obtain phosphorous fertilizers.
Способ состоит в следующем. Отходы после крэкинга систематически извлекаютс слабой сол ной кислотой, причем в раствор переход т хлористый алюминий и хлористое железо. Крепкий раствор хлористого алюмини подвергают очистке от железа путем электролиза с применением угольных анодов и железных или медных катодов. Катодные пространства отделены от анодного с помощью диафрагм.The method consists in the following. The waste after cracking is systematically extracted with weak hydrochloric acid, and aluminum chloride and iron chloride are transferred to the solution. A strong solution of aluminum chloride is purified from iron by electrolysis using carbon anodes and iron or copper cathodes. The cathode spaces are separated from the anodic with the help of diaphragms.

ЛИЗ дает удовлетворительные результатн при соблюдении следующих трех условий: 1) температура должна быть не выше 40°; 2) наиболее выгодна катодна плотность около 70 амп1м. При более высоких плотност х тока увеличиваетс расход энергии, при меньших же плотност х тока не достигаетс нужна степень очистки; З) необходима достаточна циркул ци электролита.LIZ gives satisfactory results if the following three conditions are met: 1) the temperature must be no higher than 40 °; 2) the most profitable cathode density is about 70 amp1m. At higher current densities, energy consumption increases, while at lower current densities, the degree of purification is not reached; H) sufficient electrolyte circulation is necessary.
Из очищенного от железа раствора хлористого алюмини выдел ют Путем упаривани гидрат хлористого алюмини , который далее, по известным методам, разлагаетс на чистую окись алюмини и сол ную кислоту.From the iron-free aluminum chloride solution, the aluminum chloride hydrate is separated by evaporation, which is further decomposed by known methods into pure alumina and hydrochloric acid.
