Description

,54} СПОСОБ ПОЛУЧЕНИЯ ГИДРАТИРОВАННОЙ ДВУОКИ Cii НИР КОН И Я, 54} METHOD OF OBTAINING A HYDRATED TWO CI NON KON AND ME

Иэобре-гение относитс  к способу получени  регенерируемых поглотителен двуокиси углерода из влажной атм(х:фе ры герметичных объемов иа основе гидратированной двуокиси циркоин .Ibre-genie relates to a method for producing regenerable carbon dioxide absorptive materials from wet atm (x: fraction of pressurized volumes based on hydrated zircoin dioxide.

Известен способ получени  гндрати- рованной двуокиси циркони , основанный на взаимодействии растворов солей циркони  с растворами щелочных металлов и аммиака с дальнейшей про -{ывкой и сушкой осадковГ .A known method of obtaining hydrated zirconia is based on the interaction of solutions of zirconium salts with solutions of alkali metals and ammonia with further proc - ing and drying of precipitates.

Способ заключаетс  в следующемThe method is as follows.

В разбавленные (0,3-1,0 м) растворы солей циркони  (нитрат оксоциркони  и хлорид циркони ) в 0,5-1,5 н, раст« воре соответствуюшей кислоты (азотной или хлористоводородной) добавл ют 1 н. р 1створы гидроокисей натри , кали , цези  и аммони  при различных значени х рН (4-5; 6-7; 8 -9; 1О -11), Све™ жеосажденные гели выдерживают дл  созревани  в маточном р ;тзоре опреде™ ленное epeMsi (О, 24, 48, 72 час), после чего фильтруют и прокрываютTo diluted (0.3-1.0 m) solutions of zirconium salts (oxocirconium nitrate and zirconium chloride) in 0.5-1.5 N, dilute the corresponding acid (nitric or hydrochloric acid) with 1 n. P 1 solutions of sodium, potassium, cesium, and ammonium hydroxides at different pH values (4-5; 6-7; 8-9; 1-0-11); Fresh ™ homogenized gels are kept for maturation in the uterine p; tzore certain epeMsi O, 24, 48, 72 hours), then filtered and covered

Недостаток протот}$па состоит в том, что пол чегШР г.фнаедеиным способом Г1 драт}1роват1а  двуокись Щ1ркони  мало пригодна дл  адсорбиин СО а нз влажного воздуха, так как гфе  ставл ет собой твердью зерна, которые легко растpecKissaioTCH при контакте с капельножидкой водой и которые трудно тонко изметьчить дл  получени  шюзтичного материала при формовшгии в механически гфс ные гранулы с помощьло св зующего вешества. Кроме того, полученные наавашвим способом сорбенты обладают отиосЕтельно низкой сорбцлонной акт1 Бнсстью по двуокиси углерода.up to a negative reaction to umi chloride nitrate ions. Dissolving the gel at a temperature of 201OO C, as well as in the Bs yyivfHOM exsnator at 4 ° C, With this, from the final product of the final product with synthesis conditions. The lack of prototype pas is that the floor by means of the ice method G1 Drat} 1 of Sch1rconi dioxide is not suitable for adsorbine CO and nz of humid air, since the soil is a solid grain that is easily grown by contacting with water and water. which are difficult to fine-tune to obtain schuzztic material when molded into mechanically hf granules with the aid of a binding substance. In addition, the sorbents obtained using the Navashivim method have a very low sorbtslonnoy act1 Carbon dioxide.

Цель изобретени  - повышение дисперсносиз н сорбшюкной емкссти по СОд , т.е. получение гидрат ровашюйThe purpose of the invention is to increase the dispersion of sorption of emulsion by SO, i.e. getting rovash hydrate
