Preparation and characterization of an effective sorbent for SO2 and NOx removal using coal washery reject

TL;DRAbstract

The work presented in this thesis, in general, involves preparation and characterization of sorbents for SO2 and NOx removal using waste carbonaceous materials. The specific objectives of this project are to fundamentally investigate into (1)          the feasibility of utilization of coal washery reject m preparation of an effective sorbent for toxic gas removal from flue gases; (2)          structural and adsorptive properties of coal reject-derived sorbents; (3)          mechanisms and kinetics of the preparation processes as well as the sorption of SO2 and NOx onto the sorbents. A series of experimental and theoretical studies were carried out to fulfill the objectives of this work. These studies are mainly on the preparation processes such as pyrolysis in inert atmosphere and activation in oxidative gases, and also on the sorption and reaction of SO2 in the carbonaceous sorbent developed. The principal experimental techniques used include (a) Thermogravimetric Analyzer (TGA) for k
