糠醛气相脱羰催化剂的制备和再生研究

Preparation and regeneration of catalyst for gas-phase furfural decarbonylation

糠醛经过脱羰反应生成的呋喃是一类应用广泛的化工产品。目前脱羰反应主要有气相脱羰和液相脱羰,液相脱羰反应对环境的污染比较严重,其发展受到了限制。气相脱羰反应则因活性高、污染小逐渐成为主要的研究方向。笔者主要对气相脱羰用催化剂的制备及表征、活性测试、再生方法进行研究分析。

Furan is a kind of widely used chemical products obtained from decarbonylation of furfural. At present, the decarbonylation reaction mainly includes gas-phase and liquid-phase decarbonylation. However, the development of liquid-phase decarbonylation has been restricted because of the serious pollution of reaction process. The gas-phase decarbonylation reaction has become the main research direction due to its high activity and low pollution. In this paper, the preparation and characterization of gas-phase decarbonylation catalyst, activity test, and regeneration method are introduced and discussed.
