Description

technical field [0001] The invention relates to a control test device for preparing bio-oil by rapid pyrolysis of biomass, and belongs to the technical field of biomass recycling and energy conversion equipment. Background technique [0002] In recent years, the shortage of petrochemical energy resources and the deterioration of the ecological environment have received widespread attention, and the development of renewable energy has received widespread attention. Among the many renewable energy sources, biomass energy has the characteristics of uniqueness, safety, and compatibility, so it has broad prospects for development and utilization. Among many biomass energy utilization technologies, fast biomass pyrolysis technology can directly convert low-energy-density solid biomass into high-grade energy products and materials—bio-oil, clean gas and activated carbon powder. The research hotspot is considered to be a biomass energy conversion technology with great development p...
