Catalytic conversion of ethanol to high value-added chemicals
摘要
Abstract
Biomass ethanol is the building block for producing a variety of high value-added chemicals(e.g.acetaldehyde,olefins,butanol and high carbon alcohols,aromatic alcohols/aldehydes,etc.)through catalytic dehydrogenation,dehydration,aldol condensation,cyclization,etc.The catalytic conversion of biomass ethanol to high value-added chemicals is a green route with low carbon emission and high atomic economy.Due to the complexity of the ethanol reaction network,the main concern for this pathway is the synergy of different catalytic active sites with matched elemental reaction rates.This article reviews the research progress of heterogeneous catalytic ethanol conversion to high value-added chemicals according to the types of products based on the understanding of the active center,reaction pathway and reaction mechanism.For the catalyst system and reaction mechanism,the synergetic modulation of multi-active center and the structure-performance relationship are summarized.The regulation mechanism of the product distribution is clarified.It is also pointed out that the preparation of higher value-added C6+alcohols and aromatic oxygenate from ethanol is the most promising research in the future.From the industrial application viewpoint,there is an urgent need to develop integrated reaction-separation technology for ethanol conversion and utilization.关键词
