Изобретение относитс к извлечению ванади из отработаннЕ гх катализаторов дл окислени сернистого ангидрида и может быть исполь-эовано в черной и цветн.ой металлургии, химической и нефтехимической и друг их отрасл х промышленности.The invention relates to the recovery of vanadium from waste catalysts for the oxidation of sulfur dioxide and can be used in ferrous and non-ferrous metallurgy, chemical and petrochemical and other industries.
Цель изобретени - сокращение числа операций и ускорение процесса.The purpose of the invention is to reduce the number of operations and speed up the process.
Пример 1. ДО,00 г отработанного ванадиевого катализатора СВД (размолотого, просе нного через сито со 100 отв./см , с содержанием А,2% ) выщелачивают водным раствором гидразинсульфата (60 мл). Количество гидразинсульфата в растворе О,А г (1% от веса катализатора, отношение Ж:Т 1,5:1). Начальна температура выщелачивани 60 С, далее процесс продолжают без подогрева. Врем выщелачивани 2,5 ч. Раствор после выщелачивани фильтруют с получением ванадийсодержащего фильтрата, в котором содержалось 1,63 г/л Vjd; (получают 1 л раствора), соответственно этому извлечение ванади в раствор 97%.Example 1. BEFORE, 00 g of spent SVP vanadium catalyst (milled, sifted through a sieve with 100 holes / cm, with A content, 2%) is leached with an aqueous solution of hydrazine sulfate (60 ml). The amount of hydrazine sulfate in the solution is O, A g (1% by weight of the catalyst, the ratio W: T 1.5: 1). The initial leaching temperature is 60 ° C, then the process is continued without heating. Leaching time 2.5 hours. The solution after leaching is filtered to obtain a vanadium-containing filtrate, which contained 1.63 g / l Vjd; (get 1 l of solution), respectively, the extraction of vanadium in a solution of 97%.
Приме р 2. 40,00 г отработанного ванадиевого катализатора СВС (размолотого, просе нного через сито со 100 отв,/см, с содержанием 3,1% VjОу) выщелачивают водным раствором гидразинсульфата (80 мл). Количество гидразинсульфата в растворе 0,8 г (2% от веса катализатора, ). Выщелачивание вели в услови х примера 1 .Example 2. 40.00 g of spent vanadium SHS catalyst (milled, sieved through a sieve with 100 holes, / cm, with a content of 3.1% VjOy) is leached with an aqueous solution of hydrazine sulfate (80 ml). The amount of hydrazine sulfate in the solution is 0.8 g (2% by weight of the catalyst,). Leaching was carried out under the conditions of Example 1.
После фильтрации раствора от выщелачивани получали ванадийсодержащий фильтрат, который содержал 1,2 г/л VjOj ( получали 1 л раствора), соответственно извлечение ванади в раствор составл ло 96,5%.After filtration of the leaching solution, a vanadium-containing filtrate was obtained, which contained 1.2 g / l VjOj (1 l of solution was obtained), respectively, vanadium extraction into the solution was 96.5%.
П р и м е р 3. 40,00 г отработанного катализатора ИК-1-4 (размолотого , просе нного через сито со 100 отв./см , с содержанием 6,2%PRI me R 3. 40.00 g of spent catalyst IK-1-4 (milled, sifted through a sieve with 100 holes / cm, with a content of 6.2%
Vj C)g) выщелачивают водным раствором гидразинсульфата (60 мл). Количество гидразинсульфата в растворе 0,4 г (1% от веса катализатора, Ж:Т 1,5:1).Vj C) g) is leached with an aqueous solution of hydrazine sulfate (60 ml). The amount of hydrazine sulfate in the solution is 0.4 g (1% by weight of the catalyst, G: T 1.5: 1).
Вьщ5елачивание вели в услови х примера 1. После фильтрации раствора от вьш5елачивани получали ванадий содержащий фильтрат, который содержалAllocation was carried out under the conditions of Example 1. After filtration of the solution from the extinction, vanadium containing filtrate was obtained, which contained
2,13 г/л VjOj (получали 1 л раствора )-, соответственно извлечению ванади в раствор составл ло 86,0%.2.13 g / l VjOj (received 1 l of solution) -, according to the extraction of vanadium in the solution was 86.0%.
Услови и результаты вьпцелачивани приведены в таблице.The conditions and results of aiming are shown in the table.
