Abstract
"PROCESSO PARA TRATAR MATERIAIS CARBONADOS". A presente invenção refere-se a processos para reduzir a quantidade de impurezas contendo enxofre nos materiais carbonados são descritos. Um processo compreende contatar os materiais com uma solução aquosa de ácido hidrofluorsilícico na ausência do fluoreto de hidrogênio sob condições onde pelo menos um pouco das impurezas que contêm enxofre reage com o ácido hidrofluorsilícico para formar produtos de reação e separar os produtos de reação dos materiais carbonados. Um outro processo compreende contatar os materiais com uma solução aquosa de ácido hidrofluorsilícico na ausência de fluoreto de hidrogênio sob condições onde pelo menos um pouco das impurezas contendo enxofre reage com o ácido hidrofluorsilícico para formar produtos de reação, separar os produtos de reação e o ácido hidrofluorsilícico dos materiais carbonados e subseq³entemente tratar os materiais carbonados com uma solução de ácido de flúor que compreende uma solução aquosa de ácido hidrofluorsilícico e fluoreto de hidrogênio. Um processo adicional compreende tratar os materiais carbonados com uma solução de ácido de flúor que compreende uma solução aquosa de ácido hidrofluorsilícico e fluoreto de hidrogênio, separar os materiais carbonados da solução aquosa do ácido hidrofluorsilícico e fluoreto de hidrogênio e a seguir contatar os materiais carbonados com um solvente orgânico capaz de dissolver o enxofre elementar."PROCESS TO TREAT CARBON MATERIALS". The present invention relates to processes for reducing the amount of sulfur-containing impurities in carbonaceous materials are described. One process comprises contacting the materials with an aqueous hydrofluoric acid solution in the absence of hydrogen fluoride under conditions where at least some of the sulfur-containing impurities react with hydrofluoric acid to form reaction products and separate reaction products from carbonated materials. . Another process comprises contacting the materials with an aqueous hydrofluoric acid solution in the absence of hydrogen fluoride under conditions where at least some of the sulfur-containing impurities react with hydrofluoric acid to form reaction products, separate reaction products and acid. hydrofluoric acid of the carbonaceous materials and subsequently treating the carbonaceous materials with a fluorine acid solution comprising an aqueous hydrofluorosilicic acid and hydrogen fluoride solution. A further process comprises treating the carbonaceous materials with a fluorine acid solution comprising an aqueous hydrofluorsilicic acid and hydrogen fluoride solution, separating the carbonated materials from the aqueous solution of the hydrofluorsilicic acid and hydrogen fluoride, and then contacting the carbonated materials with an organic solvent capable of dissolving elemental sulfur.
