Abstract: Abstract: Biomass carbonization technology refers to the process of biochar, bio-oil, and non-condensable gas products’ formation from raw biomass material. This process occurs in the anaerobic or hypoxic environment, which is a low-temperature slow pyrolysis technology. Biomass pyrolysis and multi-generation technology uses modern biomass carbonization technology as the core. Bio-carbon, high-quality gas, wood tar and wood vinegar and other products are produced through the separation and purification of pyrolysis gas. Biochar can be widely used in carbon sequestration, water purification, heavy metal adsorption and soil improvement. Thus, biochar production and application have attracted wide attention of domestic and foreign researchers. Pyrolysis gas has an important development and utilization value as a high-quality clean gas. With the advantages of high utilization rate of resources, diversified product forms and less secondary pollution, this technology can further improve the development and utilization of comprehensive benefits. It also meets the strategic thinking on comprehensive utilization of biomass energy resources, and has a good prospect of popularization and application. Continuous biomass carbonization technology represents the future development direction of biomass carbonization technology, with the advantages of good production continuity, high productivity, convenient process controlling and relatively stable product quality. In view of the fact that most of the biomass carbonization equipment has poor continuity, high energy consumption and secondary tar pollution, the carbon, gas, and oil co-production process scheme was put forward. Combined with the latest development in the biomass carbonization technology and the raw material characteristics of agricultural and forestry residues, continuous segmentation pyrolysis, multi-stage combined dust removal and fuel/gas reuse heating process methods were used. Based on it, the technologies of evenly and orderly multi-level screw board material delivering, efficient multi-cavity swirl cascade heat transferring, insulated settled and sealed char launching, with system pressure and gas component coupling early warning obtained the breakthrough. In addition, biomass continuous pyrolysis test production system was also developed. When this equipment worked, the raw material was orderly reversed with the rotation of continuous pyrolysis reaction tube in the reaction chamber. Dehydration, volatile precipitation and cracking reaction occurred during this process. As the material fell down, the biochar was separated from the gas. The biochar entered into thermal insulation device and was further carbonized in the oxygen and heat insulation environment. After being cooled down, the production was sequentially output through the screw conveyor. As for the pyrolysis gas, it was transferred to the high-pressure gas storage device using the booster pump after the steps of dust removal, multi-stage condensation, and scrubbing. To form a micro-positive pressure carbonization environment in the reaction chamber, this system would control the air volume in real time with the help of pressure signal feedback. The result showed that the system was stable and reliable. Using the peanut shell as the raw material, its treatment capacity was 28.2 kg/h, the biochar yield was 31.3%, the gas calorific value was 16.3 MJ/m3, and the temperature control precision was ±10 ℃. All of the technical indicators reached the system design goals and requirements. In this way, the pilot system development provided the foundation for equipment amplification and demonstration applications. Biomass pyrolysis and polygeneration can further improve the comprehensive development and utilization benefits of biomass resources, in line with the comprehensive utilization strategic thinking of biomass energy, which has a good application prospect.
