Embodiment Construction
[0033] The present invention will be described below with reference to the accompanying drawings.
[0034] The invention provides a method and a device for preparing oxygen-containing liquid fuel through catalytic conversion of bio-oil. In this method, biomass is first subjected to thermal cracking to produce oil, and the obtained bio-oil is separated from the water phase and the oil phase, and hydrogen is produced from the oil-phase bio-oil through a chemical chain method to provide a "hydrogen source" for the water-phase bio-oil in the slurry bed Two-step catalytic hydrogenation, hydrogenated products (polyols) are directly separated and purified to obtain oxygenated liquid fuels. The device includes biomass fast thermal cracking device 1, gas-solid separator 2, fast condenser 3, oil-water phase separator 4, reduction reactor 5, steam hydrogen generator 6, air reactor 7, compressor one (first Compressor) 8. Compressor 2 (second compressor) 9. Slurry bed low-temperature cata...
