Straw-refining is an environmentally friendly and high efficiency process, and also a focus in international academic and industry.It will be an inevitable way to solve energy, resources and environmental crisis and to achieve sustainable development.However, due to the materials complex structures, the lignocellulosic biomass refining industrial technology system has not yet been set up in the world.Although there are many researches on the efficient conversion of lignoeellulosic raw materials,the key problems in current are: 1) how to effectively overcome the recalcitrance of lignocellulosic biomass in the hiodegradation processes; 2) how to achieve the selective directional depolymerization, polymerization and functional conversion of the raw materials; 3) how to effectively and economically integrate series of processes for the conversion of solid complex lignocellulose material.
