Two Zn-based sorbents, named as L-991 and L-992, used for hot gas desulfurization were developed. The L-992, which was prepared by changing Zn/Ti ratio and adding certain proportion of Cu and Mn metal oxide, has better performance than L-991. The suitable desulfurization temperature was 600–700 °C for the L-991 and 600–800 °C for the L-992. The sulfur capacity was about 16 g/100 g and 19–21 g/100 g...
This paper introduced two new zinc-based sorbents for hot gas desulfurization, G-201 and G-202. Evaluation tests proved that both G-201 and G-202 sorbents had good performance in desulfurization. They could reduce H 2 S concentration from about 10 g/m 3 in coal gas to less than 20 mg/m 3 . In addition, the sulfur capacity of both sorbents increased with temperature rising....
