Изобретение относитс  к очистке газов от микропримесей и может быть применено дл  очистки азота, водорода, инертных тазов и углеводородов от паров воды, кислорода, сероводорода , арсина, фосфина и других преимущественно протонодонорных примесей.The invention relates to the purification of gases from microimpurities and can be applied to the purification of nitrogen, hydrogen, inert pelvis and hydrocarbons from water vapor, oxygen, hydrogen sulfide, arsine, phosphine and other predominantly proton-donor impurities.

Известен способ очистки газов от вышеуказанных примесей путем контактировани  их с металлоорганическими соединени ми.A known method of cleaning gases from the above impurities by contacting them with organometallic compounds.

С помош,ью этого способа можно осуществить весьма тонкую очистку до остаточных концентраций в несколько .With the help of this method, it is possible to carry out a very fine purification to a residual concentration of several.

Однако из-за большой пожаро- и взрывоопасности этот способ находит лишь лабораторное применение.However, due to the high fire and explosion hazard this method finds only laboratory use.

Предлагаемый способ отличаетс  от известного тем, что металлооргапическое соединение, например, триалкилалюминий нанос т на инертный пористый носитель. В качестве носителей используют пемзу, пористый кирпич и другие пористые материалы, не содержащие кислых центров.The proposed method differs from the known one in that a metal-orbic compound, for example, a trialkyl aluminum, is deposited on an inert porous carrier. Pumice, porous brick and other porous materials that do not contain acidic centers are used as carriers.

Полученный таким образом поглотитель не самовозгораетс  на воздухе и при контакте с водой не взрывает.The absorber obtained in this way does not ignite spontaneously in air and does not explode when in contact with water.

Одновременно за счет резкого увеличени  поверхности, па которой идет массообмен,значительпо возрастает степень очистки. Например , остаточное содержание паров воды при одинаковых услови х уменьшаетс  в 10 раз, кислорода - в 4 раза,At the same time, due to a sharp increase in the surface, where mass transfer takes place, the degree of purification increases significantly. For example, the residual content of water vapor under the same conditions decreases by a factor of 10, oxygen by 4 times,

Пример 1. Измельченный носитель (с размерами частиц 4-10 мм) промывают разбавленпой сол ной кислотой, прокаливают при 700-800°С, охлаждают в токе азота и в тойExample 1. A crushed carrier (with a particle size of 4–10 mm) is washed with dilute hydrochloric acid, calcined at 700–800 ° C, cooled in a stream of nitrogen, and in that

же среде внос т в колонку. Затем носитель пропитывают 10%-ным раствором трпизобутилалюмини  в изопентане.the medium is added to the column. Then the carrier is impregnated with a 10% solution of trisabutylaluminum in isopentane.

Пропитку осуществл ют в несколько этапов. Каждый этап состоит из насыщени  носител The impregnation is carried out in several steps. Each stage consists of carrier saturation

раствором, удалени  раствора и отдувки растворител  током азота. Количество нанесенного триизобутилалюмини  составл ет 50 г на 1 кг носител . Через колонку с поглотителем пропускаютsolution, removing the solution and stripping the solvent with a stream of nitrogen. The amount of triisobutyl aluminum applied is 50 g per kg of carrier. Pass through the absorber column

поток азота с примесью паров воды и кислорода с объемной скоростью 100 . Концентрации паров воды и кислорода на входе - 0,0035 и 0,03% соответственно, на выходе - 0,00008 ц 0,0056%.a stream of nitrogen mixed with water vapor and oxygen with a bulk velocity of 100. Concentrations of water vapor and oxygen at the inlet are 0.0035 and 0.03%, respectively, and at the outlet, 0.00008 c 0.005656.

Пример 2. Через колонку, заполненную тем же поглотителем, пропускают поток ацетилена , содержащего 0,01% РНз и 0,01% AsHa. Эмиссионный спектр газа на выходе показывает отсутствие фосфора и мышь ка.Example 2. A column of acetylene containing 0.01% RNz and 0.01% AsHa is passed through a column filled with the same absorber. The emission spectrum of the output gas shows the absence of phosphorus and arsenic.
