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...
