综述了五羰基铁衍生煤液化催化剂的研究进展。五羰基铁衍生催化剂是多种煤样加氢液化最活跃的催化剂之一。当使用低硫含量的煤时，为了获得高活性，需要向铁中添加等量的硫。羰基铁衍生的催化剂的活性物质归因于磁黄铁矿，通过 XRD 和穆斯堡尔光谱研究确定其中一些具有纳米级尺寸。使用铁羰基硫催化剂进行煤液化的动力学研究表明，催化剂的作用是促进氢从气相直接转移到煤碎片自由基的过程
The development of iron pentacarbonyl derived coal liquefaction catalyst is summarized. Iron pentacarbonyl derived catalyst is one of the most active catalysts for the hydroliquefaction of a variety of coal samples. When low sulfur content coal was employed, the addition of an equivalent amount of sulfur to iron was necessary in order to achieve high activity. The active species of iron carbonyl derived catalyst is attributed to pyrrhotite, some of which is of nanosize order as determined by XRD and Mossbauer spectroscopic investigation. Kinetic studies of coal liquefaction using iron carbonyl sulfur catalyst showed that the role of catalyst is to promote direct hydrogen-transfer process from gas phase to coal fragment radicals
