Description

идрогеп , которь:р послелоолтепьно иогтpfpraoT обработке раствором концетрации 8 г/п, раствором (0,5 г/п) нитрптов редкоземельных элементов церне- вой подгруппы и затем вновь раствором ( в r/п). Поспе третьей обработки шарики гидрогел  промывают паровым кон-  гнсатом и сушат при ISO С, 11росушенны шдрики гидрогел  подвергают обработке 0,1 н. раствором серной кислоты при температуре 8О С в течение 4 час, Обработанный таким образом адсорбент промываю паровым конденсатом и сушат при темпера туре 2 СО С. Пример 2. 1,7 н. раствор силиката натри  и 1,2 н. раствор .4 в количествах соответственно 6ОО и ЗОО г/час смешивают в струйном смесители с вощюй суспензией ueonHTaNa 4концентрации 90-100 г/л и копи шстве 160-210 п/час при температуре 7-8 С. Образовавнгийс  золь подвергают затем коагул ции в Шарики гидрогел  и обрабатывают последовательно сначала смесью растворов Idropep, which is: treatment of the concentration solution with a solution of 8 g / n, a solution (0.5 g / n) of nitrates of the rare-earth elements of the cerium subgroup, and then again with a solution (in r / n). After the third treatment, the hydrogel beads are washed with steam condensate and dried at ISO C, 11 dried shdrika hydrogel is treated with 0.1 n. sulfuric acid solution at a temperature of 8 ° C for 4 hours. The adsorbent treated in this way is washed with steam condensate and dried at a temperature of 2 CO C. Example 2. 1.7 n. sodium silicate solution and 1.2 g. solution .4 in quantities of 6OO and ZOO g / hr, respectively, are mixed in a jet mixer with a wax suspension of ueonHTaNa 4 concentration of 90-100 g / l and a saving of 160-210 p / h at a temperature of 7-8 C. The formation of sol is then coagulated in The balls are hydrogel and are treated sequentially first with a mixture of solutions.

Промытые после ак тивации и просушенные шарики гидрогел  обрабатывают О.1 н, раствором серной кислоты при 70 С в течение 4 час. Затем адсорбент промывают дистиллированной в6« дои и сушат при температуре 20О С. В таблице приведены сравнительные качества цеолитсодержащего адсорбен та , полученного предлагаемым и извест- I Ным способами. Из данных таблицы видно, что введение стадии активации О,1 н. раствором серной кислоты значительно повышает его адсорб- .циошгые свойства. Полученный по предлагаeмo /ly способу адсорбент обладает более развитыми удельными поверхностью и объе-; мом пор,  вл етс  более селективным по отношению;к. аромат1гческим углеводородам.The rate of nitrite mmoi (I 6-2O i / l) and syrphgm rare earth metal el-meth in (npfMW, l iton, neodymium, proeodymium) contliterii 0.8-1.2 g / l at 42-52 24 hours, and the solution with a solution (20 g / l) of ammonium nitrate. Washed, after activation, and dried hydrogel beads are treated with O.1 n, sulfuric acid solution at 70 ° C for 4 hours. Then the adsorbent is washed with distilled B6 до mildew and dried at a temperature of 20 С. C. The table shows the comparative qualities of the zeolite-containing adsorbent obtained by the proposed and known methods. From the data table shows that the introduction of the activation stage O, 1 n. Sulfuric acid solution significantly increases its adsorb- tion properties. The adsorbent obtained by the proposed / ly method has a more developed specific surface area and volume; this is more selective in relation to; aromatic hydrocarbons.
