Abstract

<p><tt>Coal derived oil is produced by the reaction of hydrogen and coal slurry which is mixture of pulverized coal,recycle solvent and catalyst particles,In the coal liquefaction equipment,the slurry causes erosion of the valves and blockage of the pipeline,The following were carried out as a prevention :design change of equipments and improvement on operation technQlogy、The erosion is thought to be caused by the ash of coal an(1the hard partides of iron used as a catalyst.Therefore,the effect of the use of ultra nne particles of soft molybdenum su1飼e instead of the use of pyrite particles as a iron catalyst was investigated.The control of the erosion of the valves was expected.This molybdenum su1且de catalyst showed the high activity and the generation of carbon dioxide using this catalyst was suppressed.We think this catalyst </tt><tt>improve the process of the coal liquefaction. </tt></p>
