摘要：

The mechanism of WGSR has been studied on an Fe-Cr catalyst. Although after reaction (from 250 to 400°C) formate species have been characterized on the Fe-Cr catalyst, by chemical trapping, TPD studies after reaction and after HCOOH adsorption have shown that formates are not the main intermediates. The disproportionation of CO or the regenerative mechanism seems to be more probable. © 1990 Akadémiai Kiadó.
