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...

Abstract

The invention provides a device and a method for preparing oxygen-containing liquid fuel by catalytically converting biological oil. The device comprises a biomass rapid thermal cracking oil preparing system (I), a biological oil oil-water phase separation system (II), an oil phase biological oil chemical chain hydrogen production system (III) and a hydrogen output water supply phase biological oil catalytic hydrogenation system (IV), wherein the biomass rapid thermal cracking oil preparing system is used for preparing the biological oil; the biological oil oil-water phase separation system is used for receiving the biological oil and separating the biological oil into oil-phase biological oil and water-phase biological oil to be respectively output to the oil phase biological oil chemical chain hydrogen production system (III) and the hydrogen output water supply phase biological oil catalytic hydrogenation system (IV). The method comprises the following steps of: carrying out heat cracking on a biomass to prepare oil; carrying out water phase and oil phase separation on the obtained biological oil; carrying out chemical chain method on the oil-phase biological oil to produce hydrogen; and providing a'hydrogen source' to the water-phase biological oil to carry out two-step catalytic hydrogenation in a slurry bed; and directly separating and extracting a hydrogenated product to obtain the oxygen-containing liquid fuel. The device and method disclosed by the invention can be used for realizing full-component'graded conversion' of the biological oil.

Description

technical field [0001] The invention discloses a method and a device for preparing oxygen-containing liquid fuel through catalytic conversion of bio-oil, and relates to the field of utilization of biomass resources. Background technique [0002] Biomass energy is the only "multi-functional" renewable energy that can be converted into gas, solid and liquid fuels and can completely replace fossil energy. It focuses on the development of high-end biomass-based fuels that can replace petroleum-based liquid fuels and chemicals. Products (oxygenated liquid fuels and high-value chemicals) will help fundamentally alleviate my country's oil shortage situation, ensure national energy security, and meet the major strategic needs of my country's national development. At present, the mainstream technologies for converting biomass into liquid fuels at home and abroad include biochemical conversion and thermochemical conversion. Among them, biomass pyrolysis liquefaction technology is one o...
