Research on the Corn Stalk Composite Solvent Liquefaction

The northeast of China with rich sources of corn straw resources as raw materials, we take use of multi-component solvent as the liquefaction. Ethylene glycol, polyethylene glycol (200) and glycerol，the three kinds of solvent mixing for liquefacient. We got the optimum process conditions, which is reaction temperature is 160 °C, reaction time is 60 minutes, catalyst amount to total liquefied agent is 3%. On the product analysis shows that the solvent liquefied corn straw can be effectively degradation. The results indicated that the liquefaction products contains phenols, aldehydes, et al, such as carboxylic acid group material, which can be converted into the corresponding ether, ester etc polymer compound that can be used in plastic, building heat preservation etc partly replace at present, these resources products from petrochemical. Straw liquefaction can reduce dependence on fossil energy, and make up for a single energy products of the shortcomings of the economy, which have great significant strategic.
