Description
Синтез аммиака в технике производитс действием смешанных железных катализаторов, приготовл емых плавлением:The synthesis of ammonia in the technique is produced by the action of mixed iron catalysts prepared by melting:
1)окислов железа с активаторами электротоком;1) iron oxides with activators of electric current;
2)металлического железа при окислении его кислородом; при этом сплав с активаторами образуетс за счет выдел ющегос тепла окислени железа;2) metallic iron during its oxidation by oxygen; in this case, an alloy with activators is formed due to the released heat of iron oxidation;
3)еще примен етс способ приготовлени аммиачных катализаторов образованием комплексных соединений железа .3) the method of preparing ammonia catalysts is also used to form iron complex compounds.
Активаторами во всех случа х, главным образом, служат окислы щелочных и щелочноземельных металлов, а также AlaOa и SiOg в различных комбинаци х .The activators in all cases are mainly oxides of alkali and alkaline-earth metals, as well as AlaOa and SiOg in various combinations.
Проведенными автором в Госуд. И-те высоких давлений работами вы влено, что, если после окислени чистого железа кислородом образующуюс расплавленную массу вместе с добавленными активаторами нагреть каким-либо способом и поддержать окисленный продукт некоторое врем , то охлажденный сплав представл ет собой активный и устойчивый катализатор синтеза аммиака.Conducted by the author in Gosud. High-pressure works have revealed that, after oxidizing pure iron with oxygen, the resulting molten mass together with the added activators is heated in some way and the oxidized product is kept for some time, the cooled alloy is an active and stable ammonia synthesis catalyst.
Приготовление производитс следующим образом. Металлическое железоPreparation is carried out as follows. Metallic iron
(5)(five)
окисл етс кислородом, образующиес окислы плав тс вследствие выдел ющегос тепла, прибавл ютс порци ми активаторы и железо; когда окислительный процесс заканчиваетс , то начинаетс нагревание жидкого сплава каким-либо способом до более высокой температуры, при не прекращаемом дутье кислорода. Жидкий сплав выдерживаетс при высокой температуре некоторое врем .oxidized with oxygen, the resulting oxides melt due to the heat generated, activators and iron are added in portions; when the oxidation process is completed, the liquid alloy is heated in some way to a higher temperature, with uninterrupted oxygen blowing. The molten alloy is kept at a high temperature for some time.
Получаетс низко-температурный активный и устойчивый катализатор. Переплавка с добавлением небольшого количества А12Оз + повышает активность катализатора.A low temperature active and stable catalyst is obtained. Melting with the addition of a small amount of A12Oz + increases the activity of the catalyst.
Пример. Q кг обыкновенной поделочной стали были расплавлены порци ми при помощи ацетилено-кислородной горелки с добавочным дутьем кислорода и к каждой порции прибавлены глинозем и азотнокислый калий. Когда все железо было расплавлено и были внесены все активаторы (0,4 кг AljOa н 0,8 кг KNOg), то начали одним дутьем кислорода окисл ть и переплавл ть всю массу до начала затвердевани . Вслед за этой операцией мощной ацетиленовой горелкой в присутствии слабого дуть кислорода массу хорощо переплавили, выдержав некоторое врем в расплавленном состо нии. Затем катализатор былExample. Q kg of ordinary commercial steel was melted in portions using an acetylene-oxygen torch with an additional blast of oxygen, and alumina and potassium nitrate were added to each portion. When all the iron was melted and all activators were added (0.4 kg AljOa and 0.8 kg KNOg), they began to oxidize with a single blast of oxygen and melt the whole mass before solidification. Following this operation, a powerful acetylene torch in the presence of weak oxygen blowing the mass was well melted, having stood for some time in the molten state. Then the catalyst was
