DIRECT LIQUEFYING METHOD OF COAL WITH IRON ORE TREATED WITH WATER AND SULFUR AS CATALYST

摘要

PURPOSE:To liquefy coal directly, by forming a paste from a finely pulverized coal, mixing oil and a disposable catalyst consisting of an iron ore powder treated with activating water and sulfur, and reacting the resultant paste with hydrogen under a high temperature and pressure. CONSTITUTION:(A) 10-50pts.wt. finely pulverized coal having a particle size =about 60 mesh is uniformly mixed with (B) 90-50pts.wt. mixing oil having a boiling point of about 300-380 deg.C and (C) a disposable catalyst consisting of an iron ore powder treated with activating water and sulfur in an amount of 0.03- 0.3pt.wt. based on one pt.wt. coal, to form a paste. The resultant paste is then reacted at a hydrogen partial pressure of about 15.0-30.0MPa and a temperature of about 420-470 deg.C preferably for 10-15min to liquefy the coal directly. The treatment of the iron ore with the activating water is carried out by treating the iron ore powder with boiling water for 30min-2hr, and drying the treated iron ore powder.
