May 16 2007 · ABSTRACT Desulfurization of coal involves the removal of both the inorganic and organic forms of sulfur Several physical methods are available for the removal of inorganic sulfur which is normally represented by pyritic and sulfatic sulfur Removal of organic sulfur requires the use of chemical cleaning methodsGet Price
Jul 01 1993 · Thermophilic mixed cultures were identified that removed 90 of pyritic and sulfate sulfur and 33 of the organic sulfur from North Dakota lignite The 30–40 organic desulfurization barrier was studied for possible inhibitors to organic sulfur removal from coalGet Price
Nov 01 1999 · The effects of temperature on sulfur removal were investigated using the water soluble fraction of 20 g of wood ash for 10 g coal under 17 MPa partial pressure of oxygen for 30 min at 500 min −1 stirring speed Relations between the temperature and total sulfur removal from the coal samples are shown in Fig l of the total sulfur content increased continuously with increasingGet Price
Activated Carbon For Sulfur Removal Hydrogen Sulfide is a very volatile dissolved gas and readily escapes as a gas into the air causing unpleasant odors Once hydrogen sulfide leaves the dissolved phase and enters the gas phase it can cause odor and corrosion Desulfuration active carbon isGet Price
Jan 01 2020 · Inorganic sulfur in coal could be easily removed by the most economical physical method while organic sulfur removal was difficult due to the complexity of coal macromolecular structure As shown in Fig 1 organic sulfur mainly existed in the form of five kinds of sulfurcontaining groups including thiols thiophene thioether sulfoxideGet Price
SULFUR DIOXIDE REMOVAL There are no combustion strategies that can be used to control the generation of sulfur dioxide in PC plants If sulfur is present in coal it will be converted into sulfur dioxide during combustion The only recourse is to capture the sulfur either before the coal is burned using a coalcleaning processGet Price
removal in both of coal samples Pyritic sulfur removal was achieved at higher percentage than organic sulfur but it could be said that the degree of degradation depends on the nature and composition of coal because of the closeness of sulfur removal percentage of pyritic and organic sulfur in Hazro coal sample The removal of ash was around 27 at the highest alkali to coal ratioGet Price
Sulfur removal during coal pyrolysis at different conditions varies from 15 to 40 depending on coal sample pyrolysis temperature and time For most coal samples the sulfur content in char isGet Price
treatment of coal for sulfur removal sulfur capture during combustion and postcombustion treatment of flue gas Removal of sulfur techniques are classified as physical chemical thermal and biological Such techniques are extensively applied for coal desulfurization prior to combustion Most of research work on coal desulfurization has been focused on pyritic sulfur removalGet Price
Oct 23 2019 · Last year two articles by Chinese scientists from multiple institutions in Jiangsu Shandong and Beijing applied our potassiumbased method to remove the sulfur from raw coalGet Price
