  • Device for preparing bio-oil, system for preparing bio-oil and method for preparing bio-oil using the same
    Patent number: 9005313
    Abstract: A device for preparing bio-oil, a system for preparing bio-oil and a method for preparing bio-oil using the same are provided. Biomass is supplied to an inclined portion of a reactor, and high-temperature hot sand is supplied to an upper side of the biomass supplied to the inclined portion. Then, a heater heats the inclined portion. Thus, the fast pyrolysis performance of the biomass can be enhanced, thereby increasing the yield of bio-oil. Also, combustion gas produced from the heater is supplied to the interior of the reactor, so that the interior of the reactor can be simply formed under a nonoxidizing atmosphere. Accordingly, the device for preparing bio-oil can be manufactured into a very simple structure.
    Type: Grant
