Preparation and Characterization of Iron-based High-temperature Water-gas Shift Catalysts with Ball Milling Method
高能球磨法制备铁基CO高温变换催化剂及其性能表征

The high-energy ball milling method was applied to prepare traditional iron?chromium-based CO high-temperature water gas shift reaction (WGSR) catalysts. The effects of milling time and K2O promoter on the catalytic activity of catalysts were investigated. The structure and morphology of catalysts were characterized by XRD, BET, and SEM, and the catalyst reducibility was measured by TPR. The results showed that the catalytic activity of catalysts without any treatment increased from 65.17% to 74.78% with th...
