Embodiment 1
[0040] This example is used to illustrate the method of the present invention for producing biomass oil and syngas from biomass.
[0041] Such as figure 1 As shown, sawdust (particle size 0.07-3mm, composition as shown in Table 1 below) was heated to 150 °C as biomass, and then added to the fluidized bed cracking reactor, and mixed with high-temperature heat carrier (quartz) from the heater sand, the particle size is 0.04-1mm, the temperature is 850°C), the temperature of the reactor bed is controlled to be 500°C, and the reaction is carried out at 0.1MPa for 10 minutes. Oil gas and solid products are obtained after treatment in a fluidized bed cracking reactor. The oil gas is introduced into the subsequent oil and gas separation system to separate cracked gas and biomass oil. The cracked gas is injected into the heater for combustion to heat the recycled heat carrier. The solid product is introduced into the solid separator (fluidized bed reactor) for solid separation, and t...
Embodiment 2
[0045] This example is used to illustrate the method of the present invention for producing biomass oil and syngas from biomass.
[0046] Sawdust (particle size 0.07-2 mm, composition as shown in Table 1 above) is heated to 200°C as biomass, and then added to the fluidized bed cracking reactor, and mixed with high-temperature heat carrier (quartz sand, granules) from the heater The size is 0.04-1mm, the temperature is 800°C), the temperature of the reactor bed is controlled to be 400°C, and the reaction is carried out at 0.1MPa for 15 minutes. Oil gas and solid products are obtained after treatment in a fluidized bed cracking reactor. The oil gas is introduced into the subsequent oil and gas separation system to separate cracked gas and biomass oil. The cracked gas is injected into the heater for combustion to heat the recycled heat carrier. The solid product is introduced into the solid separator (fluidized bed reactor) for solid separation, and the separated heat carrier ent...
Embodiment 3
[0048] This example is used to illustrate the method of the present invention for producing biomass oil and syngas from biomass.
[0049] Sawdust (particle size 0.07-3 mm, composition as shown in Table 1 above) is heated to 150°C as biomass, and then added to the fluidized bed cracking reactor, and mixed with high-temperature heat carrier (quartz sand, granules) from the heater The size is 1-2mm, the temperature is 850°C), the temperature of the reactor bed is controlled to be 600°C, and the reaction is carried out at 0.1MPa for 5 minutes. Oil gas and solid products are obtained after treatment in a fluidized bed cracking reactor. The oil gas is introduced into the subsequent oil and gas separation system to separate cracked gas and biomass oil. The cracked gas is injected into the heater for combustion to heat the recycled heat carrier. The solid product is introduced into the solid separator (fluidized bed reactor) for solid separation, and the separated heat carrier enters ...
