What are the sulfides in the gasification products?
Thread Content
May I ask the seniors, what sulfides are present in the syngas produced by the gasifier? I want to know about both inorganic sulfur and organic sulfur! Thank you!
H2S and COS, thiol CH3CH2SH
Most of the sulfur was converted into H2S (about 95% of the total), but there were also very small amounts of COS, SO2, as well as various thiol compounds (C2H5SH) and thiophenes (C4H4S). The sulfur content in gas is related to the sulfur content in the fuel as well as the processing method.
70%-80% of the sulfur in coal is converted into gases, of which about 95% exists in the form of H2S, while the remainder is present in the form of organic sulfur
In addition to what was mentioned by the person in charge on the 4th floor, about 10% goes into the solid slag, forming slag substances such as sulfates and sulfides.
