表面活性剂用量对完全液相法制备的Cu-Zn-Al合成醇催化剂性能影响
Effect of surfactant dosage on the performance of Cu-Zn-Al catalyst prepared by complete liquid-phase technology for alcohol synthesis
摘要
Abstract
Cu-Zn-Al slurry catalysts were prepared by a complete liquid-phase technology and characterized by XRD, H2-TPR and NH3-TPD. The effect of dosage of the surfactant polyvinylpyrrolidone(PVP)used for catalyst preparation on the performance of catalysts in synthesis of higher alcohols from syngas was investigated. The results showed that increasing PVP amount could improve selectivity of C2+ alcohols and reduce methanol formation. PVP amount affected Cu° particle size of the catalysts, which was closely related to selectivity of alcohols. The smaller the Cu° particle size was, the higher the selectivity of methanol was. The larger the Cu° particle size was, the higher the selectivity of C2+ alcohols was.关键词
