System for coproducing gas-liquid fuel, chemicals and carbon material by catalytic pyrolysis of biomass

Abstract

The invention discloses a system for coproducing a gas-liquid fuel, chemicals and a carbon material by catalytic pyrolysis of biomass. The system comprises a biomass in-situ catalytic pyrolysis poly-generation subsystem, a pyrolysis volatile online catalytic proton extraction system, a non-condensable gas catalytic reforming subsystem and a charcoal activation ammoniation modification subsystem. The biomass in-situ catalytic pyrolysis poly-generation subsystem is used for carrying out in-situ catalytic pyrolysis on the biomass to obtain pyrolysis volatile components and biochar; the pyrolysisvolatile online catalytic proton extraction system is used for carrying out multistage online catalytic upgrading, multistage cooling and separation purification on volatile components to obtain phenolic chemicals and an aromatic hydrocarbon fuel; the non-condensable gas catalytic reforming subsystem performs multistage catalytic reforming on the pyrolysis gas to obtain methane-rich gas fuel for power generation and heat supply; and the charcoal activation ammoniation modification subsystem performs sufficient ammoniation activation modification on charcoal to obtain the high-value nitrogen-doped carbon material. The goal of green, efficient and continuous preparation of electricity, heat, chemicals and carbon materials is achieved.

Description

technical field [0001] The invention relates to the field of biomass catalytic pyrolysis, in particular to a system for co-producing gas-liquid fuels, chemicals and carbon materials through catalytic pyrolysis of biomass. Background technique [0002] Biomass energy has the characteristics of green, clean, large annual output, and renewable, and is an ideal alternative energy source for fossil fuels. At the same time, biomass energy is the only carbon-containing renewable resource on the earth, and it has characteristics that other renewable resources (such as solar energy, wind energy, etc.) cannot match. Converting biomass energy into high value-added gaseous fuels, liquid fuels, organic chemicals, and functional carbon materials is an inevitable development direction for high-value utilization of biomass energy. Biomass catalytic pyrolysis is an important way to realize the production of high-value chemicals, gas or liquid fuels from biomass. [0003] At present, the co...
