Abstract
Рассматривается способ снижения содержания серосодержащих примесей в углеродных материалах. Один способ включает контактирование материалов с водным раствором кремнефтористо-водородной кислоты в отсутствие фторида водорода в условиях, в которых по меньшей мере часть серосодержащих примесей взаимодействует с кремнефтористо-водородной кислотой с образованием продуктов реакции, и отделение последних от углеродных материалов. Другой способ включает контактирование материалов с водным раствором кремнефтористо-водородной кислоты в отсутствие фторида водорода в условиях, в которых по меньшей мере часть серосодержащих примесей взаимодействует с кремнефтористо-водородной кислотой с образованием продуктов реакции; отделение указанных продуктов реакции и кремнефтористо-водородной кислоты от углеродных материалов; и последующую обработку углеродных материалов фторсодержащим кислым раствором, который содержит водный раствор кремнефтористо-водородной кислоты и фторида водорода. Другой способ включает обработку углеродных материалов фторсодержащим кислым раствором, который содержит водный раствор кремнефтористо-водородной кислоты и фторида водорода; отделение углеродных материалов от водного раствора кремнефтористо-водородной кислоты и фторида водорода и затем контактирование углеродных материалов с органическим растворителем, способным растворять элементарную серу.Международная заявка была опубликована вместе с отчетом о международном поиске.
