摘要: Abstract The present work investigated the feasibility of heterocyclic sulfur (HS) removal for coal utilizing potassium tert-butoxide and hydrosilane system. Changes forms with treatment time in Xinyu (XY) were determined by XANES. Results showed that reductions total organic XY 55% 53%, respectively. >85% sulfoether thiophene removed after treated 4 h, suggesting HS could be to a high extent from coal. However, contents sulfonate sulfonic ester increased due hydrolysis oxidation intermediate products containing Si S bands. Furthermore, it indicated selectively without destroying macromolecular structure based on analysis desulfurization mechanism. These findings suggested refractory obtained using tert-butoxide/hydrosilane reductive system, which provided reference
