Calcium oxide, lithium oxide and titanium oxide were investigated as additives of zinc oxide for the removal of hydrogen sulfide at high temperature.
This experiment was performed in the range of 1.0-2.0 vol.% H₂S concentration at 623-873 K reaction temperature, using a thermogravimetric analyzer.
A pore blocking model was found to fit the reaction rate and the kinetics data were sucessfully expressed by this model. The reactions between additive sorbents and hydrogen sulfide were first order with respect to hydrogen sulfide concentration in a gaseous mixture with nitrogen.
Among the used sorbents, ZnO-CaO 0.5 at.% and ZnO-TiO₂ 2.0 at.% sorbents had the best additive effects on the sulfidation reaction between additive sorbents and hydrogen sulfide, whereas the ZnO-Li₂O sorbents were ineffective.
