Abstract
PURPOSE: To lessen the amount of hydrogen used in the second hydrogenating and liquefying reaction, to raise the efficiency of denitration, and to obtain a clean liquefied oil, by washing the liquid reaction product of the first hydrogenating and liquefying reaction with an inorganic acid so that basic nitrogen compounds are removed, followed by subjecting the reaction product to the second hydrogenating and liquefying reaction.
CONSTITUTION: Raw brown coal is blended with a catalyst and a solvent in the slurry tank 1 with stirring, the preheated blend together with hydrogen is sent to the first hydrogenating and liquefying column 4, and passed through the vapor- liquid separator 5 and the solid-liquid separator 6 to the washing device 7. In the device, the reaction product is washed with an inorganic acid, basic nitrogen compounds and alkali metals are removed as salts, and the reaction product is transferred through the oil-water separator 13 and it together with hydrogen gas is sent to the second hydrogenating and liquefying column 8.
