摘　　要：赤泥、炼铁高炉飞灰、硫铁矿烧渣和硫铁矿含有Fe2O3及Fe S2等有效的铁基催化剂前驱体,均能提高煤油共炼转化率;粒径对催化剂活性的影响显著超过活性组分质量分数和比表面积;赤泥催化作用最显著,对煤的转化率、沥青质转化率、汽柴油收率分别达到76.23%、48.71%和30.56%;赤泥中少量Fe OOH的存在可起到促进催化的作用,而除去Ca O及Na2O或者掺杂Ti O2对煤油共炼反应没有促进作用。The red mud,the flash ash from blast furnace iron-making process,the pyrite cinder and iron pyrite are able to enhance the conversion rate of coal / oil co-process,because they all contain the effective catalyst precursor such as Fe2O3,Fe S2,and so on. The particle size controlls the catalyst activity,whereas the amount of Fe2O3 and the surface area have negligible influence. The red mud shows the best catalyst activity. The conversion rate of coal and asphaltene are76. 23%,48. 71%,respectively. The yield of gasoline can reach 30. 56%. The existence of slight amount of Fe OOH probably increases the catalyst activity of red mud,while the removal of the Ca O and Na2 O,or addition of Ti O2 have no observable promotion in the coal / oil co-processing.
