Abstract

Cette invention concerne des procédés permettant de réduire la teneur en impuretés renferment du soufre dans des matières carbonées. Un de ces procédés consistent à mettre les matières en contact avec une solution aqueuse d'acide hydrofluorosilicique en l'absence de fluorure d'hydrogène dans des conditions telles qu'une partie au moins des impuretés contenant du soufre forment des produits de réaction et à séparer ces produits de réaction des matières carbonées. Un autre procédé consiste à mettre ces matières en contact avec une solution aqueuse d'acide hydrofluoroisilicique en l'absence de fluorure d'hydrogène dans des conditions telles que partie au moins des impuretés contenant du soufre réagissent avec l'acide hydrofluorosilicique pour former des produits de réaction, à séparer lesdits produits set l'acide hydrofluorosilicique des matières carbonées et de traiter ensuite ces matières carbonées avec uns solution d'acide de fluor comprenant une solution d'acide hydrfluorosilicique et de fluorure d'hydrogène. Un autre procédé encore consiste à traiter les matières carbonées à l'aide d'une solution d'acide de fluor comprenant une solution aqueuse d'acide hydrofluorocilicique et de fluorure d'hydrogène, à séparer les matières carbonées de ladite solution, puis de mettre les matières carbonées en contact avec un solvant organique capable de dissoudre le soufre élémentaire.
