Chat Online· Some researchers studied sulfur removal from coal with reduction additives . Sodium borohydride was utilized to desulfurization of coal water slurry whose desulfurization processing was shown in reaction (3) . Active hydrogen atoms were produced after the additives reacted with water and reduced sulfur atoms to form sulfur-containing gases.
Chat Online· Removal of the mineral matter (or "ash") 3 which is largely noncombustible and may constitute up to 65 percent of the raw coal increases the heating value of the coal on a mass basis. 4 Although some combustible material is lost as part of the cleaning process the removal of unwanted material reduces the mass and volume of coal for a
Chat OnlineCoal waste and coal slurry are the largest industrial waste generated from coal preparation plants. This paper describes a method to make clean coal briquette with coal waste and coal slurry. Two binders were used during the coal briquette making process. In addition a mixture of cacium hydroxide and coal fly ash was added into the formulation acting as a sulfur retention agent.
