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.A method for reducing the content of sulfur-containing impurities in carbon materials is considered. One method involves contacting materials with an aqueous solution of hydrofluoric acid in the absence of hydrogen fluoride under conditions in which at least some of the sulfur-containing impurities interact with fluoric hydrofluoric acid to form reaction products, and separating the latter from carbon materials. Another method involves contacting materials with an aqueous solution of hydrofluoric acid in the absence of hydrogen fluoride under conditions in which at least some of the sulfur-containing impurities interact with fluoric hydrofluoric acid to form reaction products; separating said reaction products and fluorosilicic acid from carbon materials; and the subsequent processing of carbon materials with a fluorine-containing acidic solution, which contains an aqueous solution of fluorosilicic acid and hydrogen fluoride. Another method involves treating carbon materials with a fluorine-containing acidic solution, which contains an aqueous solution of hydrofluoric acid and hydrogen fluoride; separating carbonaceous materials from an aqueous solution of hydrofluoric acid and hydrogen fluoride and then contacting carbonic materials with an organic solvent capable of dissolving elemental sulfur. The international application was published together with an international search report.
