USE OF PURE AND SULPHUR DOPED TiO2 NANOPARTICLES FOR HIGH TEMPERATURE CATALYTIC DESTRUCTION OF H2S GAS

H2S reduction over Pure and Sulphur doped TiO2 nanoparticles was studied in this work. The parameter was catalytic destruction of H2S gas under high temperature of 450C using fixed bed catalytic system under laboratory conditions. Under these conditions 99.97% reduction was achieved using S-doped TiO2. 2.89% Sulphur was adsorbed on S-doped TiO2 nanoparticles to form Ti(SO4)2. Comparatively, no significant reduction in the H2S gas concentration was observed using Pure TiO2. The XRD, SEM and EDX techniques were performed to characterize the nanoparticles and gas reduction analysis was done using GC-MS for gas samples. FTIR analysis was carried out to investigate the byproducts of the experiments.
