By using two different methods of dispersion and sulfurization, the water-soluble Fe catalyst precursor was dispersed in oil and be characterized after the reaction. The results show that, the average particle size of the iron pyrite crystal is smaller while the emulsion breaking respectively at lower temperature and breaking the emulsion together at higher temperature. The water-solubility salts turns into Fe7S8 and the crystal which piled by little globate catalyst is closeness when the emulsion breaking respectively at 300°C, however The water-solubility salts turns into Fe9S11 and the crystal piled by little globate catalyst is loosen when breaking the emulsion together at 300°C, and as the sulfurization temperature is increased, the better crystal of iron pyrite will be formed. while the emulsion breaking respectively at 300°C, the coke restraining ability of the catalyst is better than that of the catalyst when breaking the emulsion together at the same temperature, and the coke restraining ability of the catalyst will decreased as the sulfurization time prolonged.
