摘要

Disclosed is a method for preparing bio-oil, which can be used as bio heavy fuel oil and bio marine oil, from a fatty acid with high acid value. The method for preparing bio-oil comprises the steps of: inputting materials comprising glycerine and a fatty acid into respective material input ports positioned in the center of a column-type reactor and esterification reacting the material comprising glycerine and fatty acid in each tray of a reaction area, thereby producing glyceride and water, wherein the column-type reactor has the plurality of trays installed inside the reactor so as to form a plurality of compartments in the vertical direction inside the reactor, openings are formed in the plurality of trays to connect the compartments which are vertically adjacent, and the openings of the adjacent compartments are alternately formed in a crisscrossing manner; obtaining the produced glyceride through a lower part of the reactor; and vaporizing the water produced by the esterification reaction, moving the water in a vapor state to a distillation area in an upper part of the reactor to separate the water from active components (reaction material and bio-oil) comprised in the vapor, allowing the separated active components to flow into the reaction area, and removing the separated water through the upper part of the reactor in a vapor state. The acid value of the glyceride is 30 mgKOH/g or lower, and the esterification reaction is performed at a reaction temperature of 200 to 250 ℃ and at ordinary pressure without using a catalyst.
