Problems solved by technology

With the in-depth research on biomass pyrolysis process and the continuous improvement of production scale and production rate requirements, researchers have found that the disadvantages of existing reactors are becoming more and more obvious, mainly including the poor mixing and contact effect of heat carrier and biomass raw materials, which leads to heat loss. The transfer rate is low, the residence time cannot be accurately controlled, resulting in the occurrence of non-ideal secondary reactions, and the rapid separation of pyrolysis steam from coke, ash, etc., which affects the quality and yield of bio-oil, etc.
