Embodiment 1
[0033] This example is used to illustrate the method of the present invention for preparing biomass oil and synthesis gas from biomass.
[0034] Such as figure 1 As shown, sawdust (particle size 0.07-2 mm, composition shown in Table 1 below) as biomass is heated to 150°C, then added to the fluidized bed cracking reactor, and contacted with the high temperature gas from the burner, control The bed temperature of the reactor was 500°C, and the reaction was carried out at 0.2 MPa for 10 minutes. After being processed by a fluidized bed cracking reactor, oil and gas and coke are obtained, and the oil and gas are introduced into the subsequent oil and gas separation system to separate cracked gas and biomass oil. Coke is introduced into the gasification reactor, and a mixture of 50 parts by weight of steam and oxygen (600°C) based on 100 parts by weight of coke is introduced into the gasification reactor, where the moles of steam and oxygen are 6:1, the gasification reaction is carr...
Embodiment 2
[0038] This example is used to illustrate the method of the present invention for preparing biomass oil and synthesis gas from biomass.
[0039] Sawdust (particle size 0.07-2 mm, composition as shown in Table 1 above) as biomass is heated to 150 ℃, and then added to the fluidized bed cracking reactor, and contact with the high temperature gas from the burner to control the reactor bed The layer temperature was 400°C, and the reaction was carried out at 0.1 MPa for 5 minutes. After being processed by a fluidized bed cracking reactor, oil and gas and coke are obtained, and the oil and gas are introduced into the subsequent oil and gas separation system to separate cracked gas and biomass oil. Coke is introduced into the gasification reactor, and 50 parts by weight of steam and oxygen mixed gas (200°C) based on 100 parts by weight of coke is introduced into the gasification reactor, where the moles of steam and oxygen are 6:1, the gasification reaction is carried out at 800°C and 0...
