Study on the multicomponent catalytic liquefaction technology of corn stalk features

Abstract

Using rich corn straw resources as raw materials, which come from the northeast China. It is liquefied by multicomponent compound solvent, testing the reaction time, reaction temperature and the dosage of the catalyst. These process conditions are inspected for the liquefaction of the corn stalk and the chemical test and instrumental analysis used for the liquefied products. Finally the best process conditions have been obtained. The result shows that the liquefied product contains phenols, aldehydes, the double bond containing compound and carboxylic acids. These substances can be converted into the corresponding ethers and other high molecular compound, which can be applied to produce biodegradable materials and chemicals product in the industries of plastic, construction, insulation and so on. Crop straws could be converted into industrial raw material by catalyzed liquefaction. These industrial raw materials will replace the fossil resources which have dried up and product polymer materials which are good for the environment. Alternative petrochemical from the liquefaction product will reduce the pollution of the agricultural waste straw on tone environment as well as the consumption of the fossil resources. Given the biological degradation, there is a deep significance on the environment and sustainable development. At the same time, the liquefaction of corn stalk can reduce the dependence on fossil fuels and makeup the economy with single energy products. The market potential is tremendous and strategic importance is obvious.
