The thesis studied the effect of catalyst preparation methods
and additives on the vanadium-based catalyst preformances for
the selective oxidation of hydrogen sulfide. In addition,BET、
SEM、XRD and ESCA were used for catalyst characterization.
Six different methods were used to prepare the catalyst with Sb/
V=1.0 and the best method was found to be the one prepared with
oxalic acid. However,for catalyst with Sb/V=0.3 ,the catalyst
prepa- red with nitric acid had better performance than the one
prepared with oxalic acid.
The different calcination temperature (450、600、850℃) were
used to prepare the catalyst with Sb/V=1.0 and the best
calcination temperature was found to be at 450℃.
Three different supports (TiO2、ZrO2、γ-Al2O3) were used to
pre- pare supported catalyst with Sb/V=0.3 . Both TiO2 and ZrO2
supported catalysts reached the surfur yield of 100％, but ZrO2
supported cata- lyst had better catalytic activity.
