Characteristics of the Fe/Cr/Cu catalyst pellet in the high-temperature water-gas shift reaction

The Fe/Cr/Cu catalyst pellet was prepared for application in the high-temperature water-gas shift reaction (HTWGSR) to produce hydrogen from the gasified gases of waste plastics. The Fe/Cr/Cu catalyst pellet was synthesized using a compression molding method with the prepared catalyst powder. The HTWGSR was conducted using the prepared catalyst pellet with CO: H₂O ratios of 1: 2 and 1: 3 at a temperature range of 300 ℃ to 400 ℃. The maximum average CO conversion of the Fe/Cr/Cu catalyst pellet was observed at a CO: H₂O ratio of 1: 2, with a value of 87%. These results suggest that the prepared Fe/Cr/Cu catalyst pellet is suitable for high-temperature water-gas shift reactions in terms of CO conversion.
