Low Cost Coal-based Carbons for Combined So2 and No Removal from Exhaust Gas

Coal Ash as a Low Cost Adsorbent for the Removal of Xylenol Orange from Aqueous Solution

The removal ofxylenol orange from aqueous solution onto the coal ash was investigated at room temperature. The results show that the adsorption capacity of xylenol orange increased as the adsorption time increased and then equilibrium established after 30 min adsorption time. The results obtained revealed that the coal ash removed about 80 % of xylenol orange from the aqueous solution withi...

Carbon-enriched coal fly ash as a precursor of activated carbons for SO2 removal.

Carbon-enriched coal fly ash was evaluated in this work as a low-cost adsorbent for SO2 removal from stack gases. The unburned carbon in coal fly ash was concentrated by mechanical sieving and vegetal oil agglomeration. The carbon concentrates were activated with steam at 900 degrees C in order to develop porosity onto the samples. The performance of these samples in the SO2 abatement was teste...

Removal of SO2 and the Simultaneous Removal of SO2 and NO from Simulated Flue Gas Streams Using Dielectric Barrier Discharge Plasmas

A gas-phase oxidation method using dielectric barrier discharges (DBDs) has been developed to remove S02 and to simultaneously remove SO, and NO from gas streams that are similar to gas streams generated by the combustion of fossil fuels. SO, and NO removal efficiencies are evaluated as a function of applied voltage, temperature, and concentrations of S02, NO, t'l,O~s), and N H 3. With constant...
