【摘要】 用微型高压釜，以四氢萘和十氢萘为溶剂，在氢初压６．０ Ｍ Ｐａ，反应温度３９０～ ４５０℃，反应时问０－６０ｍｉｎ下，添加铁化合物为催化剂进行煤炭加氢液化，考察各 种影响因素，并用穆斯堡尔谱测试液化残渣，探索其催化机理。结果表明，液化时 ＦｅＳ２完全转变为磁黄铁矿Ｆｅ１－ｘＳ；Ｆｅ２Ｏ３－Ｓ或Ｆｅ３Ｏ４－Ｓ直接或经过中间物ＦｅＳ２间接转变为磁黄铁矿。Ｆｅ１－ｘＳ生成量增多，液化转化率增大。进一步有力地证 实，Ｆｅ１－ｘＳ是以铁化合物为催化剂进行煤炭液化时的活性物种。更多还原

【Abstract】 The catalysis of fivc iron Compounds un the Zalaroure lignite hydrolique- faction are investigated with M■ssbauer spectrometer. The coal liquefaction is carried out in a microautoclave. The THF insoluble residue of liguefaction products is analysed with M■ssbauer spectrometer under room temperature. It is observed that under conditions of coal liguefaction FeS2 is completely trans- formed into pyrrhotite, and Fe2O3-S or Fe3O4-S is transformed into pyrrhotite directly or indirectly through the intermediate state of FeS2. The results show that net conversion increases mainly with increasing Fe-xS formed. Thus it is confirmed that Fe1-xS is the catalytic active species during coal liquefaction with iron compounds.更多还原
