The present disclosure relates to an apparatus and a method for measuring miscibility in oil using back titration. The apparatus includes: a flocculation solution storage unit; a flow cell including a UV transmitting member; a dissolving agent storage unit; a UV irradiation unit; and a measurement unit, wherein: a flocculation solution is stored in the flocculation solution storage unit; the flocculation solution circulates between the flocculation solution storage unit and the flow cell; the measurement unit measures the UV transmittance of the flocculation solution while the dissolving agent in the dissolving agent storage unit is supplied to the flocculation solution storage unit; the miscibility in the oil is calculated from the amount of dissolving agent supplied and a change in the UV transmittance measured by the measurement unit; and the miscibility is calculated based on a time point when the slope of increase in the UV transmittance changes.

Method for measuring a degree of homogeneity of oils using back titration and measuring apparatus using the same

Provided is a method of economically modifying low rank coal (LRC) to be high grade coal having minimized water re-absorption and minimized spontaneous ignition possibility while saving energy by coating heavy oil directly on coal without using solvent oil. Provides is a method of modifying coal using palm oil residue, including milling the coal, homogenously mixing the palm oil residue with the milled coal, melting the palm oil residue mixed with the coal so as to be coated on a surface of the coal, and simultaneously drying moisture in the coal, cooling the dried coal, and briquetting the cooled coal.

Method for reforming coal using palm residue

Disclosed is a method for preparing a metal catalyst having improved yield of alcohols. The method for preparing a metal catalyst for the production of alcohol from synthesis gas includes forming a metal catalyst; and irradiating the metal catalyst with gamma rays. The metal catalyst has improved yield of alcohols by stabilizing the metal catalyst through gamma ray irradiation to inhibit generation of hydrocarbons in catalytic reaction with synthesis gas.
