Study on Mechanisms of Liquefied Corn Bran by FT-IR

Abstract:

Liquefaction is one of the useful and effective techniques for utilizing lignocellulosic biomass, expressly, heterogeneous catalytic liquefied technology receive ever-increasing attention due to the mild reaction, such as medium temperature, usually at 150°C, and atmospheric pressure. Based on lacking of enough understanding to the direct heterogeneous catalytic liquefied behavior of biomass and the impact caused by the ingredient of the liquefaction to the properties of the polymer, meanwhile, with lacking of enough theoretical support results in the liquefaction and the quality of its polymer product is not stable, this work gives out the studies of chemical structure and composition variation before and after corn bran liquefaction. The results show that lignin and hemicellulose are rapidly liquefied at the beginning of liquefaction, and cellulose, which is the main component of residue, is difficult to liquefy. The solvolysis and condensation reaction are occurred between the component of corn bran and phenol during liquefied process. The phenol is introduced into the structure of corn bran.
