Abstract

Chemical conversion of greenhouse gas CO₂ into value-added oxygenates such as ethanol, acetic acid, propanal, propionic acid, butanol, etc. is challenging due to the complexity of C-C coupling and the uncontrollable bonding. In this review, recent research progresses on the synthesis of multi-carbon oxygenates from CO₂ in fixed bed reactor are provided. Firstly, the reaction mechanisms of CO₂ hydrogenation are summarized. Then, the potential catalysts applied in one-step or tandem CO₂ hydrogenation, dry reforming with light hydrocarbons and hydroformylation were introduced over metal carbides, alkali metal modified single or binary metal catalysts such as Cu, Fe, Co, Rh, etc. The reaction mechanism over different catalysts were further elaborated. Finally, the problems and outlook are discussed.

二氧化碳催化转化为高附加值含氧化合物的研究进展

将温室气体二氧化碳化学转化为乙醇、乙酸、丙醛、丙酸、丁醇等高附加值含氧化合物具有很大的挑战性，原因在于 C-C 偶联的复杂性和键合的不可控性。本综述介绍了在固定床反应器中以二氧化碳为原料合成多碳含氧化合物的最新研究进展。首先，总结了二氧化碳加氢的反应机理。然后，介绍了金属碳化物、碱金属改性的单一或二元金属催化剂（如 Cu、Fe、Co、Rh 等）在一步或串联 CO2 加氢、轻烃干重整和加氢甲酰化中的潜在催化剂。进一步阐述了不同催化剂的反应机理。最后，讨论了存在的问题和展望。

期刊介绍： Journal of Fuel Chemistry and Technology (Ranliao Huaxue Xuebao) is a Chinese Academy of Sciences(CAS) journal started in 1956, sponsored by the Chinese Chemical Society and the Institute of Coal Chemistry, Chinese Academy of Sciences(CAS). The journal is published bimonthly by Science Press in China and widely distributed in about 20 countries. Journal of Fuel Chemistry and Technology publishes reports of both basic and applied research in the chemistry and chemical engineering of many energy sources, including that involved in the nature, processing and utilization of coal, petroleum, oil shale, natural gas, biomass and synfuels, as well as related subjects of increasing interest such as C1 chemistry, pollutions control and new catalytic materials. Types of publications include original research articles, short communications, research notes and reviews. Both domestic and international contributors are welcome. Manuscripts written in Chinese or English will be accepted. Additional English titles, abstracts and key words should be included in Chinese manuscripts. All manuscripts are subject to critical review by the editorial committee, which is composed of about 10 foreign and 50 Chinese experts in fuel science. Journal of Fuel Chemistry and Technology has been a source of primary research work in fuel chemistry as a Chinese core scientific periodical.
