(EN) METHOD FOR PRODUCING SILICON DIOXIDE
(FR) PROCÉDÉ DE PRODUCTION DE DIOXYDE DE SILICIUM
(RU) СПОСОБ ПОЛУЧЕНИЯ ДИОКСИДА КРЕМНИЯ
Abstract
(EN)
Disclosed is a method for producing silicon dioxide from a cellulose-containing material using acid hydrolysis of a feedstock before burning same in order to produce silicon dioxide. The method makes it possible not only to produce silicon dioxide, but also to isolate carbonaceous materials such as monosaccharides and lignin as additional products, while expending less energy.
(FR)
Le procédé de production de dioxyde de silicium à partir de matière cellulosique en utilisant l’hydrolyse par acide des matières à premier avant sa combustion pour la production de dioxyde de silicium. Le procédé permet, avec des dépenses énergétiques réduites, d'obtenir non seulement le dioxyde de silicium mais aussi de dégager des matières carbonées tels que les monosaccharides et la lignine en tant que produits supplémentaires.
(RU)
Раскрыт способ получения диоксида кремния из целлюлозосодержащего материала с использованием кислотного гидролиза сырья перед его сжиганием для получения диоксида кремния. Способ позволяет при уменьшенных энергозатратах получать не только диоксид кремния, но и выделять углеродсодержащие материалы, такие как моносахариды и лигнин в качестве дополнительных продуктов.
