Compared with renewable energy sources such as solar energy, wind energy, tidal energy, nuclear energy and the like, biomass is the only renewable resource containing carbon, and the renewable organic carbon source attribute of the biomass enables the biomass to be used for combustion power generation, and can be used for preparing alternative fuels suitable for engine combustion and fine platform chemicals suitable for large-scale chemical production. Biomass is the only green resource capable of comprehensively replacing petrochemical resources, so that the development of biomass energy has important significance for further pushing energy structure transformation, reducing petrochemical energy consumption and relieving environmental problems caused by the petrochemical energy structure transformation.

Therefore, the waste yield is large in the biomass refining process, which results in low overall utilization of biomass and the generated waste requires additional cost for disposal. In addition, most biomass refining processes require hydrogen and solvents to participate in, and the required hydrogen and solvents are generally available for outsourcing, thus the cost is high, and the economy of biomass refining is further reduced.
