Background technique

Pyrolysis is an important technology for converting biomass into high value-added products. The pyrolysis method can conveniently decompose lignocellulosic biomass macromolecules into various valuable products. Among biomass pyrolysis products, the liquid product—bio-oil—has been extensively and deeply studied in recent years. Bio-oil is a mixture of complex oxygen-containing organic compounds, containing hundreds of organic compounds, many of which have high added value, such as levoglucosan, levoglucosone, glycolaldehyde, maltol, furfural Wait. On the other hand, pyrolysis coke, a solid product produced by biomass pyrolysis, is not only an excellent fuel, but also can be further processed into high value-added products such as activated carbon; Rich in methane and hydrogen, it is a gas with a medium calorific value and has the potential to be processed into high-quality civil gas.

Therefore, compared with the biomass liquefaction technology based on bio-oil, the biomass carbonization technology based on coke, and the biomass pyrolysis gasification technology based on gas, the biomass pyrolysis multi-stage technology based on the comprehensive utilization of pyrolysis products The production process has significant advantages both in terms of technological advancement and process economy. However, although the liquid products produced by the current polygeneration process have achieved the initial enrichment of the target components through staged condensation, the composition of the condensed products obtained at each stage is still complex, and the pH value is still low. In order to meet the feed requirements of fine chemicals It still needs to invest a lot of pre-treatment costs; at the same time, the grade of pyrolysis coke obtained by the polygeneration process is relatively low, and it is mostly used as fuel carbon at present. To improve the grade of coke, it still needs subsequent modification and activation treatment.

Patent ZL201210241955.7 discloses a continuous biomass pyrolysis carbon gas-oil polygeneration system, but this system only obtains medium and high calorific value gas, bio-oil and coke products, and there are complex components of bio-oil liquid products, The PH value is low, the content of high-grade components is small, and the coke grade is relatively low.
