Coal devolatilization - ScienceDirect
WebCoal devolatilization is an important step in thermal coal conversion systems such as combustion, gasification, hydro- pyrolysis, and coke manufacturing. When coal is exposed to sufficiently high temperatures it decomposes into a complex mixture of gaseous and tarry components, leaving behind a solid residue. WebApr 1, 1994 · Introduction Coal devolatilization plays an important role in major coal conversion processes, such as combustion and gasification. It has been the subject of a large number of studies for the last three decades. WebCoal pyrolysis and hydrogasification were investigated in a laboratory-scale pressurized fixed-bed reactor to examine the effects of temperature, pressure, and catalyst on the gas productivity and yields under different gas atmospheres. The experimental results show that the methane yield is significantly higher under a hydrogen atmosphere. The release rate … cabinet office it
