To remove selectively H2S and reduce SO2 emission, a regenerable hybrid TiO2/zeolite composite was developed with double advantages of zeolite adsorption
and TiO2 photocatalysis.
To verify the performance of the hybrid TiO2/zeolite composite in biogas purification, research about the effect of moisture and CO2 in biogas on H2S
removal was carried out.
Meanwhile, a research on the regeneration of TiO2/zeolite by basic washing and calcination is also conducted.
