Abstract

A series of CuO-Fe2O3 sorbents with 25 wt% SiO2 as a support were prepared based on a simple mixing method in order to evaluate the effects of Fe2O3 on their desulfurization reactivities. The initial reactivities of sorbents were tested by using a TGA and their cyclic performance was investigated in a GC/microreactor system. The activation energy calculated by the Chatterjee-Conrad method based on the TGA experiment decreased as the content of Fe2O3 increased. Sulfur loading in the cyclic reactions increased with increase of Fe2O3 content, and its maximum value was 8.9 g sulfur per 100 g sorbent.
