Introduction to the results:

Rapid pyrolysis of biomass to produce oil refers to the thermal degradation of biomass under conditions of complete hypoxia or limited oxygen supply, and the gas produced by pyrolysis is rapidly condensed to produce biomass oil. This research team has developed a spout-fluidized bed biomass rapid pyrolysis device with independent intellectual property rights to produce bio-oil. At a lower cost, a continuous production process converts low-energy-density biomass that is difficult to process with conventional methods into high-energy-density, portable and transportable biomass oil, which reduces the volume of biomass and facilitates storage and transportation.

Results Advantages:

The research team then obtained higher-quality bio-oil through quality improvement methods such as gas-phase catalysis, esterification, catalytic hydrogenation, and emulsification. Biooil is an environmentally friendly fuel, and high value-added chemicals can also be extracted from biooil.

Outcome prospects:

The resulting product biomass pyrolysis-upgrading complete equipment and technology is mainly used to convert biomass into high-quality liquid fuels and replace petroleum as vehicle fuel. The process adopts the first self-heating single bed internal circulating serial bed at home and abroad to pyrolyze biomass, and coupled with "staged conversion"(esterification-hydrogenation) technology to improve the quality of pyrolyzed bio-oil. Pilot test data shows that the biooil yield of the equipment is 10[%] higher than that of traditional twin-beds, the construction cost is 43[%] lower than that of traditional twin-beds, the operating cost is 36[%], and the investment cost is lower. After upgrading, the fuel yield for vehicles is three times as high as traditional processes, and the application prospects are broad. This achievement has currently obtained 4 national invention patents and 8 invention patents are under application.
