Description

Изобретение относитс  к области очистки газов, в частности водорода, от кислых компонентов.The invention relates to the field of gas purification, in particular hydrogen, from acid components.

Целью изобретени   вл етс  повышение степени очистки от кислых примесей и обеспечение одновременной возможности очистки от диоксида углерода.The aim of the invention is to increase the degree of purification from acidic impurities and to ensure simultaneous purification from carbon dioxide.

П р и м е р 1. Керамзит измельчают, отсеивают фракцию 1-2 мм, заливают 350 мл 25%-ного водного раствора гидроксида натри  и выдерживают 1 ч. Затем раствор сливают, контакт сушат при 120°С в течение 3 ч. Содержание гидроксида натри  в нем составл ет 21,5%.PRI me R 1. Claydite is crushed, the fraction of 1-2 mm is sifted out, 350 ml of 25% aqueous sodium hydroxide solution are poured and kept for 1 hour. Then the solution is drained, the contact is dried at 120 ° C for 3 hours. sodium hydroxide is 21.5%.

Навеску 100 г контакта помещают в аппарат диаметром 2,5 см и высотой 25 см. Через аппарат при 140°С пропускают поток газа (водорода), содержащего 0,32 мг/м3 хлористого водорода, 0,32 мг/м сероводорода и 0,32 мг/м углекислого газа с объемной скоростью 1000 ч . Степень очистки от С02-99,9%, от HCI - 100%, от H2S - 100%.A weighed 100 g of contact is placed in an apparatus 2.5 cm in diameter and 25 cm high. A stream of gas (hydrogen) containing 0.32 mg / m3 of hydrogen chloride, 0.32 mg / m of hydrogen sulfide and 0 is passed through the apparatus at 140 ° C. 32 mg / m of carbon dioxide with a volumetric rate of 1000 hours. The degree of purification from CO2-99.9%, from HCI - 100%, from H2S - 100%.

Аналогично осуществл ют примеры 2-15.Examples 2-15 are carried out in a similar manner.

Состав контактов, услови  и результаты испытаний приведены в табл. 1.The composition of the contacts, conditions and test results are given in Table. one.

Результаты аналогичных опытов по известному способу приведены в табл. 2.The results of similar experiments by a known method are given in table. 2

Таким образом предлагаемый способ очистки газов обеспечивает повышение степени очистки от кислых примесей и возможность очистки от диоксида углерода.Thus, the proposed method of gas purification provides an increase in the degree of purification from acidic impurities and the possibility of purification from carbon dioxide.
