Abstract
PURPOSE: To carry out desulfurization in the first hydrogenation and simultaneously to raise liquefaction efficiency, by adding specific amounts of iron oxide (hydrogenation catalyst) and sulfur (hydrogenation cocatalyst) respectively to a raw material slurry.
CONSTITUTION: Iron oxide as a catalyst in an amount to give 0.5W10wt% calculated as Fe based on anhydrous raw material coal free from ash and sulfur as a cocatalyst in an amount to give a ratio of iron oxide to total slurry in the raw material slurry of atom ratio Fe/S of 1.0W3.0 are added to the raw material slurry in the slurry tank 1, and the slurry is blended and stirred. The slurry from the preheater 3 together with hydrogen is sent to the first reaction column 4 for hydrogenation and liquefaction, and hydrogenating and liquefying reaction is carried out at 300W500°C at 50W700atm. The slurry is sent to the vapor-liquid separator 5, collected from the bottom of it, the liquid part from the solid-liquid separator 6 is sent from the washing device 7 to the oil-water separator 13, and the oil part is sent to the second reaction column 8 for hydrogenation and liquefaction and the second hydrogenating and liquefying reaction is done.
