The sulfide of iron-based fine particles as catalyst with dimethyldisulfide and H2S-H2 under various conditions, and the catalytic activities of those catalysts on hydrogenation and hydrocracking were investigated. The hydrogenation of 1-methyl naphtharene (1-MN) and hydrocracking of diphenylmethane (DPM) experiments were carried out in 25ml quartz tube inserted into 50ml stainless steel autoclave at 350-450℃ under 7.9MPa hydrogen initial pressure for 1hr. The crystal structure of spent iron particles were analyzed by X-ray diffractometer.
