Description

Изобретение относитс  к способам диссоциации аммиака с помощью катализаторов из металлов, например железа, никел  и др., нанесенных на носитель из окиси алюмини .This invention relates to methods for dissociating ammonia using metal catalysts, such as iron, nickel, etc., supported on alumina carrier.

Сущность изобретени  состоит в том, что в состав каталитической массы введен магний.The essence of the invention is that magnesium is introduced into the composition of the catalytic mass.

Преимуществом предлагаемого состава каталитической массы  вл етс  повышенна  активность катализатора .The advantage of the proposed composition of the catalytic mass is the increased activity of the catalyst.

Анализ кривых сопоставлени  активности катализаторов железного и предлагаемого показывает, что при 600° и объемной скорости 405 час- остаточное содержание аммиака в смеси после реактора составл ет 0,4% (степень диссоциации 99,2%), в то врем  как при работе на железном катализаторе остаточное содержание аммиака составл ет даже при 650° 36% (степень диссоциации 39%).An analysis of the comparison curves for the activity of iron catalysts and the proposed one shows that at 600 ° and a space velocity of 405 hours, the residual ammonia content in the mixture after the reactor is 0.4% (dissociation degree is 99.2%), while The catalyst has a residual ammonia content even at 650 ° -36% (the degree of dissociation is 39%).

Предложенный катализатор готов т следующим образом.The proposed catalyst is prepared as follows.

Поситель из активированной окиси алюмини  после предварительного обжига при 1000° пропитывают раствором нитратов никел , железа и магни  из расчета получени  на 100 см дробленого катализатора 3 г Ni, 3 г Fe, 0,5 г MgO. Затем просушивают катализатор при 100- 120°с выдержкой в течение двух часов и обжигают при 350°, при этом температуру со 100-120° до 350° поднимают со скоростью, не превышающей 50° в час и выдерживают при 350° не менее двух часов.After the preliminary calcination at 1000 ° C, an activated alumina bed is impregnated with a solution of nickel, iron and magnesium nitrates at the rate of obtaining 3 g of Ni, 3 g of Fe, 0.5 g of MgO per 100 cm of crushed catalyst. Then the catalyst is dried at 100-120 ° with an exposure for two hours and calcined at 350 °, while the temperature is raised from 100-120 ° to 350 ° at a speed not exceeding 50 ° per hour and maintained at 350 ° for at least two hours .

Предмет изобретени Subject invention

Способ диссоциации аммиака с помощью катализаторов из металлов , например железа, никел  и др., нанесенных на носитель из окиси алюмини , отличающийс  тем, что, с целью повышени  активности катализатора, в состав каталитиче ской массы введен магний.A method of dissociating ammonia using catalysts from metals, such as iron, nickel, etc., supported on an alumina carrier, characterized in that, in order to increase the activity of the catalyst, magnesium is introduced into the composition of the catalytic mass.
