Abstract

Adding CaO during the combustion of oil shale (OS) reduces sulfur dioxide (SO2) and nitrogen oxide (NOx) emissions, but it is challenging to synergistically control SO2 and NOx during fluidized combustion. This study utilized a lab-scale fluidized-bed reactor to explore the transformations of nitrogen and sulfur during the combustion of Chinese Beipiao oil shale (BOS) under different temperatures and Ca/S molar ratios. CaO significantly changed the combustion characteristics of OS by slowing the combustion rate of organic matter and altering the transformation mechanisms of nitrogen and sulfur. As the combustion temperature increased, the NO emissions initially rose and then decreased, while SO2 showed the opposite trend. The addition of CaO promoted the conversion of NH3 and HCN into NO and facilitated the reduction of NO to N2 through reactions with CO and char, which helped control NOx. Moreover, when the Ca/S molar ratio was 4.53, CaO reacted with released SO2 to form CaSO4, which significantly increased the sulfur fixation rate to 90.82 %. This research provides guidance for optimizing large-scale clean combustion technologies for OS and reducing pollutant emissions.
