Removal Of So2 And No From Flue Gas Using Sorbent Derived From Rice Husk Ash
The main objective of this research is to synthesize a sorbent from rice husk for simultaneous removal of SO2 and NO from flue gas. In this study, two types of rice husk ash (RHA), i.e. RHAraw and RHAinc were used. RHA was hydrated with CaO in NaOH solution and subsequently impregnated with C...

| description | The main objective of this research is to synthesize a sorbent from rice husk
for simultaneous removal of SO2 and NO from flue gas. In this study, two types of
rice husk ash (RHA), i.e. RHAraw and RHAinc were used. RHA was hydrated with
CaO in NaOH solution and subsequently impregnated with CuO. The research was
carried out by a statistical investigation on sorbent preparation parameters using
Design Expert software. Investigated sorbent preparation parameters were CuO
loading, RHA/CaO ratio, hydration period and NaOH concentration. The results
showed that CuO loading and NaOH concentration are the major parameters that
affect the sorbent’s desulfurization and denitrification activity. The optimum sorbent
preparation for RHAraw and RHAinc sorbents were 3.06% CuO loading, RHAraw/CaO
ratio of 1.41, 8.05 hours of hydration period, NaOH concentration of 0.80M and 3.04%
CuO loading, RHAinc/CaO ratio of 1.41, 19.95 hours of hydration period, NaOH
concentration of 0.20M, respectively. In addition, the effect of operating parameters
such as temperature, initial SO2 and NO concentration towards RHAraw and RHAinc
sorbents’ desulfurization and denitrification activity were also studied. Two types of
performances investigated were sorption at which 100% pollutants removal was
sustained and equilibrium removal efficiency. |
