Abstract

The invention discloses a system for co-production of nitrogenous chemicals and nitrogen-doped coke through biomass nitrogen-enriched pyrolysis. The system comprises a nitrogen-enriched pyrolysis subsystem, a coke nitrogen doping subsystem, a foreign nitrogen introducing subsystem and a nitrogen-enriched gas condensing subsystem, wherein the nitrogen-enriched pyrolysis subsystem generates high-temperature flue gas, and prompts reaction of biomass and foreign nitrogen; the nitrogen-enriched gas condensing subsystem condenses the pyrolyzed gas, and separates and stores liquid products enriched nitrogenous chemicals; the coke nitrogen doping subsystem generates high temperature gasified gas, conducts deep processing treatment on coke, and stores the cooled coke product; the foreign nitrogen introducing subsystem provides foreign nitrogen for the nitrogen-enriched pyrolysis subsystem and the coke nitrogen doping subsystem, and catches and absorbs NOx in flue gas. The system can continuously produce nitrogen-enriched oil and nitrogen-enriched coke, realizes a one-step method to prepare high-value nitrogenous chemicals and supercapacitor carbon material, and effectively prompts efficient high quality conversion of the biomass.

Description

technical field [0001] The invention relates to a system for co-producing high-value products from biomass, which is suitable for continuously converting biomass into nitrogen-containing chemicals and nitrogen-doped coke. Background technique [0002] 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...
