| Abstract: | The preparation of liquid fuels and chemicals by alcoholysis of biomass has been widely concerned. However, there are some problems such as complex products, low selectivity and unclear reaction mechanism. In this work, the reaction characteristics of carbohydrates with different degrees of polymerization in ethanol solvent were studied. The results showed that with the increase of temperature, the conversion rate of glucose, sucrose and cellobiose increased as follow: glucose > sucrose > cellobiose > cellulose. At temperatures 160-200oC, glucose mainly produced 5-hydroxymethylfurfural, while the main products of cellobiose and sucrose changed from levoglucosan to 5-hydroxymethylfurfural and from ethyl-α-ᴅ-glucopyranose to 5-hydroxymethylfurfural, respectively. |
