Polyethylene Glycol Addition Effect on Preparing Cu-Zn-O Catalysts for Low-temperature Methanol Synthesis

摘要

During the preparation of Cu-Zn-O catalyst, addition of small amount of Polyethylene Glycol (PEG) could increase the BET surface area and make Cu crystalline more finely dispersed, by stopping the sintering or agglomeration of the catalyst precursors. The PEG-added catalysts exhibited the enhanced activity for the low-temperature methanol synthesis from CO2-containing syngas, compared to their conventional analogue.
