DMO经两种反应路径加氢制乙醇催化剂研究进展
Research progress on catalysts for dimethyl oxalate hydrogenation to ethanol via two reaction pathways
摘要
Abstract
One significant route for producing ethanol(EtOH)indirectly from syngas is the hydrogenation of coal-based syngas to EtOH via dimethyl oxalate(DMO)intermediates.There are two reaction pathways for DMO hydrogenation to EtOH∶hydrogenation to EtOH via ethylene glycol(EG)intermediates and hydrogenation to EtOH via methyl acetate(MA)intermediates.The characteristics of two reaction pathways for DMO hydrogenation to EtOH were analyzed,and the catalysts commonly utilized in these pathways and the key factors affecting selectivity of EtOH were summarized.DMO hydrogenation to EtOH via EG intermediates typically requires high reaction temperature and synergistic catalysis of multiple active sites.The catalytic activity of commonly used Cu-based catalysts can be regulated from three aspects:support structure,preparation method and additive addition.The reaction temperature of DMO hydrogenation to EtOH via MA intermediates is relatively low,and commonly used catalysts are mainly transition metal carbides(Mo-base and Fe-base),but the hydrogenation capacity of catalysts is still insufficient.It helps to deepen the systematic understanding of the two pathways for DMO hydrogenation to EtOH and provides reference for the rational design and preparation of highly stable and low-cost catalysts for DMO hydrogenation to EtOH in the future.关键词
