Description

technical field [0001] The invention relates to a device in the technical field of biofuel, in particular to a device for preparing biofuel based on rapid thermal cracking of biomass for improving the quality of biofuel. Background technique [0002] Biomass rapid pyrolysis technology to produce biofuel has become a main way of biomass energy utilization, and its development has been paid attention to by countries all over the world. Currently, several types of equipment are available to accomplish this process. The rotating cone reactor was successfully developed by the Twente University Material Technology Group (BTG) in the Netherlands from 1989 to 1993; the British Wellman Company cooperated with the British Aston University and the German Wood Chemistry Research Unit, and was built in Birmingham, UK in 2000. Bubbling fluidized bed thermal cracking demonstration device with material feed rate of 250kg / h. In my country, the rapid pyrolysis of biomass to produce biofuel ...
