Speaker: Professor Changsui Zhao, Southeast University, China
I will briefly introduce our research activities in the areas of coal combustion/gasification and pollutants emission control. They cover projects on CO2 capture, fluidized bed combustion and gasification, dense phase pulverized coal/biomass pneumatic convey at high pressure, incineration and energy recovery of solid waste and high concentration organic effluent, emission and control of SO2, NOx, Hg, trace element, heavy metal and PM2.5 from coal combustion, coal/petcoke water slurry transportation and atomization etc.. I will describe in more detail our projects as follows:
-Experimental study and numerical simulation on pyrolysis/combustion characteristic and formation/control characteristic of different coals under O2/CO2 atmosphere on TGA coupled with FTIR spectrometer, drop tube furnace and 50 kWth comprehensive circulating fluidized bed facility;
-Calcium-based sorbents calcination/carbonation reaction looping including sorbent modification with ethanol, acetic acid; doped with solid waste: rice husk ash and alkaline salts: K, Na, KMnO4; condition optimization including pressurized carbonation, optimized temperature, hydration with calcium Lignosulfonate and sorbent synthesization by coprecipitation;
-Development of CO2 capture technology using solid potassium-based sorbent including choose proper active component (K2CO3 calcined from KHCO3 ) and proper supports (a special y-Al2O3); optimization of carbonation/regeneration conditions of K2CO3/Al2O3 for CO2 capture.
