Problems solved by technology

At present, the quality of bio-oil is poor (low calorific value, poor stability, strong acidity, easy to be oxidized, etc.), so its utilization is relatively difficult, so that the industrial application of this technology is not ideal
In order to improve the quality of bio-oil, the current general practice is to refine and refine bio-oil, including catalytic cracking, catalytic hydrogenation, adding additives, and emulsification with diesel oil. However, these methods require additional processes, so the cost is high and the process is difficult. complex

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...
