Continuous pyrolysis biomass coke, gas and oil poly-generation system

Abstract

The invention discloses a continuous pyrolysis biomass coke, gas and oil poly-generation system, which comprises a biomass pyrolysis assembly, a coke reforming assembly, a tar reforming assembly and abio-oil condensing assembly, wherein the biomass pyrolysis assembly is used for carrying out pyrolysis to obtain a gaseous volatile component and solid coke; the tar reforming assembly is used for accommodating an oxygen carrier and reforming the gaseous volatile component based on chemical chain oxygen decoupling; the tar reforming assembly is further connected with an oxygenization chamber andis used for reloading oxygen onto the oxygen-lost carrier to obtain the oxygen carrier cyclically applied in the tar reforming assembly; and the coke reforming assembly is used for reforming the solidcoke under the action of gas containing a non-zero valence nitrogen element. According to the continuous pyrolysis biomass coke, gas and oil poly-generation system, the biomass pyrolyzed gaseous volatile component is converted in a chained manner by introducing the oxygen carrier on the basis of the chemical chain oxygen decoupling, and all the functional assemblies in the poly-generation system,connecting relations of the functional assemblies and corresponding cooperating work modes are improved, so that high-quality biomass oil, biomass coke and combustible gas can be prepared.

Description

technical field [0001] The invention belongs to the field of high-value utilization of biomass, and more specifically, relates to a continuous pyrolysis biomass charcoal-gas-oil polygeneration system, especially a chain reforming conversion method based on chemical chain oxygen decoupling Continuous pyrolysis biomass carbon gas oil polygeneration system. Background technique [0002] Pyrolysis is the combustible pyrolysis of pyrolysis coke, pyrolysis oil and small molecules produced by breaking the chains of macromolecular hydrocarbons in solid waste under the drive of a certain temperature in an oxygen-deficient or oxygen-free environment. gas. Its advantage is that, through pyrolysis, the methane and hydrogen in the non-condensable pyrolysis gas produced are a kind of gas with medium calorific value, which has the potential to be processed into high-quality civil fuel; the produced pyrolysis oil has complex components and can reach There are hundreds of kinds, and many h...

However, the pH of the bio-oil produced in the polygeneration process is low, and the components of the bio-oil and the separation process are still complicated. complex defect

[0004] Patent 201611111821.8 discloses a biomass chemical chain gasification hydrogen production device and method based on calcium-based carbon carrier, but only a single gaseous hydrogen is produced, and pyrolysis coke is directly calcined as fuel

Patent 201210241955.7 discloses a continuous biomass pyrolysis carbon gas-oil polygeneration system. Although the co-production of high calorific value gas, coke and bio-oil has been realized, there are still many shortcomings: bio-oil components are complex and acidic High, the amount of water is too large, it cannot be directly used as a liquid fuel; the porosity of the obtained coke is not developed enough, it is difficult to be directly used as an adsorbent or high-quality carbon such as activated carbon
