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 ...

Abstract

The invention relates to a method for preparing bio-oil and synthesis gas from biomass. The method comprises the following steps: (1) in the presence of a heat carrier, biomass is subjected to a cracking reaction to obtain oil gas and solid products; (2) the oil gas undergoes oil-gas separation to separate pyrolysis gas from bio-oil; (e) the solid products undergo solid separation to separate coke from the heat carrier; and (4) the coke and a gasifying medium undergo a gasification reaction, and synthesis gas is separated from gasification reaction products. According to the method provided by the invention, bio-oil and synthesis gas can be simultaneously prepared by the use of biomass, and the prepared synthesis gas basically contains no tar.

Description

technical field [0001] The invention relates to a method for preparing biomass oil and synthesis gas from biomass. Background technique [0002] Biomass is a renewable green energy, including crop straw, forestry waste, livestock and poultry manure, urban organic waste, aquatic plants, energy plants, etc. At present, the global biomass consumption is second only to coal, oil, and natural gas, ranking fourth. According to estimates by biologists, the total amount of biomass energy grown on the earth every year is about 140-180 billion tons, which is equivalent to 10 times the current total energy consumption in the world. my country is a large agricultural country, and there is a large amount of crop waste every year, including 600 million tons of straw (rice straw, wheat straw, corn stalk, etc.) and about 389 million tons of agricultural processing residues (rice husk, bagasse, etc.). As a low-carbon, low-sulfur, low-nitrogen fuel, biomass energy has the characteristics of...
