Description

Известны способы получени  катализатора дл  синтеза аммиака из желтой кров ной соли путем осаждени  с применением промотирующих добавок в виде солей т желых металлов, например, хлористого железа, вз тых в эквивалентном количестве или в недостатке по сравнению со стехиометрически.м количеством, необходимым дл  осажденк .Methods are known for preparing a catalyst for synthesizing ammonia from yellow blood salt by precipitation with the use of promoting additives in the form of salts of heavy metals, for example, ferric chloride, taken in an equivalent amount or in deficiency compared to the stoichiometric amount required for precipitating.

Активность катализаторов, полученных по известным способам, не Зависит от того, промывают их или нет в процессе получени .The activity of the catalysts obtained by known methods does not depend on whether or not they are washed in the production process.

В способе получени  катализатора карбонитридного типа дл  синтеза аммиака, защищенном авт. св. № 134666 от 13 апрел  1960 г., примен ют стехиометрическое количество осадител  и осадок не промывают .In the method of producing a carbon-nitride type catalyst for ammonia synthesis, protected by author. St. No. 134666 dated April 13, 1960, a stoichiometric amount of precipitator is used and the precipitate is not washed.

Предлагаемый способ получени  катализатора дл  синтеза аммиакз  вл етс  дальнейщим развитием способа, защищенного авт. св. 134666 и заключаетс  в осаждении комплексной железоцианидной соли взаимодействием калийферроцианида с хлоридами двух, трех и четырех валентных металлов, вз тых в отличие от известного в избытке по сравнению со стехиометрическим количеством их, необходимым дл  осаждени .The proposed method for producing a catalyst for the synthesis of ammonia is a further development of the method protected by the author. St. 134666 and consists in the precipitation of a complex iron cyanide salt by the interaction of potassium ferrocyanide with chlorides of two, three and four valence metals, taken in contrast to the known excess in comparison with the stoichiometric amount required for the precipitation.

Вторым отличием предлагаемого способа от известного  вл етс  применение сущки лолученпого осадка с дальнейшей промывкой его в подкисленной воде и последующей сущкой.The second difference of the proposed method from the known method is the use of the semi-crystalline precipitate substance with its further washing in acidified water and the subsequent substance.

По данным авторов, эти отличи  привод т к повыщению активности и стабильности катализатора.According to the authors, these differences lead to an increase in the activity and stability of the catalyst.

Жолйчёство аммиака иа выходе из колонны составило 12,0%. Пример 2. Параллельно приготовл ют так же, как в примере 1, образец комплексного железоцианидного катализатора, состо щий из K4Ft(CN)(; . ЗЬЬО и полуторного количества А1С1з бПаО с добавкой того же количества FeClg в осадитель.The ammonia content at the exit from the column was 12.0%. Example 2. In parallel, a sample of a complex iron cyanide catalyst consisting of K4Ft (CN) was prepared in parallel as in Example 1. (;. LUT and one and a half amount of A1Cl3 bPaO with the addition of the same amount of FeClg to the precipitant.

Испытани , проведенные при тех же услови х, как и в примере 1, показали, что количество аммиака на выходе составл ет 18,5%, т. е. ур.еличение выхода аммиака составл ет 50% относительных.Tests carried out under the same conditions as in Example 1 showed that the amount of ammonia at the outlet was 18.5%, i.e. ur. The increase in the yield of ammonia was 50% relative.

Предмет изобретени Subject invention

Способ получени  катализатора дл  синтеза аммиака по авт. св. „М 134666, отличающийс  тем, что, с целью повыщени  активности и облегчени  отмывки катализатора, промотирующие добавки берут в избытке против стехиометрии, полученную катализаторную массу сушат , промывают подкисленной водой и снова сущат.A method for producing a catalyst for ammonia synthesis according to ed. St. M 134666, characterized in that, in order to increase the activity and facilitate the washing of the catalyst, the promoters are taken in excess against the stoichiometry, the resulting catalyst mass is dried, washed with acidified water and again formed.

Иа стр. 2 в строке 1 сверху напечатано железнодорожного, следует читать железоцианидного .Ea p. 2 in line 1 is printed on top of the railway, it should be read ferrocyanide.
