    摘要: Provided herein is a method for upgrading a bio-oil using a supercritical alcohol, and the bio-oil upgraded by the method, the method including removing oxygen existing in the molecule of the bio-oil using the supercritical state alcohol as a solvent and reacting the bio-oil and the alcohol solvent at supercritical state so as to increase the energy content, removing organic acids that increase the acidity of the bio-oil including formic acid and acetic acid or converting the organic acids to other materials so as to reduce the acidity, and converting hydrophilic materials in the bio-oil to hydrophobic materials so as to reduce the moisture content, and increasing the pH of the bio-oil to reduce the corrosiveness, thereby providing the effectiveness in upgrading a bio-oil.

    摘要: A fuel synthesis device includes: a supplier to supply CO2 and H2 gasses; a fuel synthesis catalyst to chemically react the CO2 and H2 gasses to synthesize fuel; a gas-liquid separator to liquefy the fuel into liquid and separate the liquid from a gas containing unreacted CO2 and H2 gasses, and CH4 gas as a side product; a return path to return the separated gas to a point between the supplier and the fuel synthesis catalyst; a bypass path to bypass, and merge downstream of, the return path, and to include a CH4 separator to separate the CH4 and a CH4 oxidation catalyst to oxidize the CH4; and a switching valve to selectively switch between communication with the return path and communication with the bypass path, wherein whether the switching valve communicates with the return path or bypass path is controlled based on the density of CH4.
