Abstract

Abstract:

Metal oxide-zeolite (OX-ZEO) bifunctional catalyst can convert CO _x hydrogenation into light olefins with high selectivity. In this work, the progresses of metal oxide in OX-ZEO catalyst for CO _x hydrogenation to light olefins are summarized, the advantages of “relay catalysis” are expounded through the thermodynamic analysis of CO _x hydrogenation to methanol/ethylene reaction, and the type and composition of metal oxide, OX-ZEO preparation method and the influence of “proximity” between oxide and SAPO-34 are mainly discussed. The catalytic reaction mechanism, the role of oxygen vacancy and the strategy to suppress side reactions are discussed. The problems and challenges of the OX-ZEO catalytic route are analyzed, and the development trend of the OX-ZEO catalytic system is prospected. It is believed that the catalytic activity can be improved by increasing the oxygen vacancies of metal oxides through elemental doping, promoter modification or optimizing preparation conditions, etc. Moreover, the by-product CO₂ generation can be suppressed by hydrophobic surface modification of the metal oxides to improve the utilization of C atoms.

Key words: syngas, carbon dioxide, light olefins, metal oxide, bifunctional catalyst, oxygen vacancy

摘要：

金属氧化物-分子筛（OX-ZEO）双功能催化剂可实现CO _x 加氢制低碳烯烃的高选择性转化。本文概述了OX-ZEO催化CO _x 加氢制低碳烯烃反应中金属氧化物的研究进展，通过对CO _x 加氢制甲醇/乙烯反应热力学分析指出了“接力催化”的优势，重点讨论了金属氧化物的种类和组成、制备方法及金属氧化物和分子筛的“亲密度”对催化性能的影响，探讨了催化反应机理、氧空位的作用及抑制副反应的策略。分析了OX-ZEO催化反应面临的问题和挑战，展望了OX-ZEO催化体系的发展趋势，认为通过元素掺杂、助剂修饰、优化制备条件等可提高金属氧化物的氧空位含量，进而可提高催化活性，也可通过对金属氧化物进行表面疏水改性抑制副产物CO₂，提高C原子利用率。
