Abstract
PURPOSE: To liquefy coal simply and efficiently under mild conditions, by a method wherein crushed coal is swelled and dispersed in a caustic soda solution, a nitrogenous fertilizer and carbonic acid are added to the resulting solution, and mixing is carried out at an ordinary temperature under normal pressure.
CONSTITUTION: Coal crushed pref. to 100 mesh size is immersed in a caustic soda solution to swell and disperse the crushed coal in the solution. To this solution are added carbonic acid and an inorg. or org. nitrogenous fertilizer such as an ammonium salt (e.g. ammonium sulfate, ammonium nitrate or ammonium chloride), a nitrate, lime nitrogen or urea. Then mixing is carried out with stirring at an ordinary temperature under normal pressure. The concentration of the caustic soda solution which is used for the immersion of the powdered coal is pref. 0.5W5%. The mole ratio of the inorg. or org. nitrogenous fertilizer to the caustic soda solution is pref. 1.2:0.2W0.2:1.2. The mole ratio of the inorg. or org. nitrogenous fertilizer to carbonic acid is perf. 0.5:1.5W1.5:0.5.
