摘要: In the present work, we for the fist time found that the Jerusalem artichoke tubers, without any treatment, were selectively transformed into low-molecular polyols with our previously developed catalyst Ni-W2C/AC. In a typical example, a conversion as high as 95.2% of jerusalem artichoke tubers was achieved at 255 oC and 6 MPa H2, and the yields of ethylene glycol, 1,2-propanediol, and glycerol were 10.5%, 28.6%, and 5.3%, respectively. It is very interesting that the yield of 1,2-propanediol is uniquely high, close to 30%. It is well known that 1,2-propanediol is a very important chemical and widely used in polyester industry. Thus, this method opens a new way to the sustainable production of chemicals from renewable biomass. Moreover, the transformation reaction is carried out in aqueous solution and the separation of solid catalyst with liquid products is very easy, thus it represents an environmentally benign process. Compared with our previously reported cellulose transformation, it is found that the product distribution differs markedly with the biomass structure fed into the reactor. When cellulose was used as the starting material, ethylene glycol was the main product. Based on the unit structure of the biomass used, a transformation pathway was proposed for the formation of 1,2-propanediol or ethylene glycol.
