The invention discloses a copper-based catalyst for starch hydrogenation sugar conversion and a preparation method and application thereof.The preparation method comprises the steps that alkali is added into a copper salt aqueous solution, filtering is conducted after aging, and hydroxide precipitates are obtained; uniformly mixing the hydroxide precipitate and the carrier to obtain a catalyst precursor, and tabletting and forming; and roasting the formed catalyst precursor at 250-900 DEG C, and then reducing by adopting hydrogen to obtain the copper-based catalyst. The catalyst shows excellent catalytic activity under the optimal reaction condition, effectively improves the yield of glucose, has good stability and reusability, and has wide application prospects in the fields of chemical engineering and biological energy.

The present invention relates to a method for disassembling forest biomass and its application. The method of the present invention changes the particle size of lignocellulose raw materials, couples with appropriate pretreatment methods for green disassembly, and then performs enzymatic hydrolysis to complete the splitting and conversion process of forest biomass. The present invention can effectively break the high-density anti-degradation barrier of forest biomass, reduce the pretreatment intensity, improve the utilization rate of component separation and extraction, and improve the pretreatment energy efficiency, thereby promoting enzymatic hydrolysis and subsequent conversion and utilization. The method utilizes the particle size effect and has the advantages of simple process, energy saving and low consumption, water saving and environmental protection, high sugar concentration, and low inhibitors.

The present application relates to a kind of freeze-thaw cycle coupling pretreatment green disassembly lignocellulose method and its application.The present application is by using water or metal salt ion solution as medium to lignocellulose raw material is carried out freeze-thaw cycle pretreatment, coupling appropriate pretreatment method is carried out green disassembly, and the obtained solid material is carried out enzymolysis to complete the disassembly and conversion process of lignocellulose.The present application can effectively break the anti-degradation barrier of lignocellulose, reduce the pretreatment intensity, improve the utilization rate of component separation extraction, reduce the inhibitor generated by pretreatment, to promote enzymolysis and subsequent conversion and utilization, and the method can utilize regional cold resource advantage, with the advantages of simple process, energy saving, water saving, environmental protection, high sugar concentration and low cost.
