Description

technical field [0001] The invention relates to the field of biological energy, in particular to a process for producing fuel oil and chemical raw materials from biomass. Background technique [0002] Biomass refers to all organic substances formed directly or indirectly by photosynthesis of green plants, including plants, animals, microorganisms and their excretion and metabolites. It is renewable, low-pollution and widely distributed. Therefore, from the perspective of energy security Starting from environmental protection, the development and utilization of biomass has become the strategic focus of the current development of renewable energy. [0003] Biomass liquefaction technology is an important part of the utilization of biomass resources. At present, it can be divided into two categories: indirect liquefaction and direct liquefaction. Among them, biomass direct liquefaction technology refers to the use of hydrolysis, ultra- Critical liquefaction or hydrogen gas, ine...
