Abstract
Изобретение относится к химической промышленности, в частности, к производству катализаторов конверсии SO2 в SO3 с использованием отработанных ванадиевых катализаторов. Способ включает выщелачивание активных компонентов в пульпе, отделение их с фильтратом от твердого остатка, обработку фильтрата и твердого остатка, смешение его с активными компонентами из фильтрата, введение компонентов свежей контактной массы, высушивание и формование. Твердый остаток после фильтрации обрабатывают раствором щелочи при мольном соотношении SiO2 / (К2О + Na2О) – V2O5 от 2,5 до 29,8 с последующим двойным осаждением SiO2 и V2O5 фильтратом или серной кислотой. Из фильтрата можно щелочью осаждать V2O5, который используют при смешивании с активными компонентами. В случае степени извлечения SiO2, равной 1,0, отработанный ванадиевый катализатор можно использовать без измельчения. Изобретение обеспечивает освобождение V2O5 из массы отработанного катализатора и повышение активности регенерированного носителя при температуре 405°С.
