AI Technical Summary
Existing technologies for the preparation of cyclopentanone suffer from high energy consumption and environmental pollution. Precious metal catalysts limit industrial applications, and there is a lack of efficient and low-cost catalysts.
Cyclopentanone was prepared by using nitrogen-doped graphene carbon nanotube/carbon shell encapsulated metal catalyst via furfural hydrogenation reaction at 180–220 °C and 1–5 MPa. The catalyst was prepared from metal salt, organic matter and deionized water, and formed an encapsulated structure after calcination.
This method enables the efficient and low-cost conversion of furfural to cyclopentanone. The catalyst exhibits good stability and low price, making it suitable for large-scale applications. It solves the problems of high energy consumption and environmental pollution in cyclopentanone preparation, and the raw materials are widely available, aligning with the concept of green development.
