抄録

We have recently proposed a coprocessing method of low-grade carbonaceous resources and a low-grade iron ore consisting of FeO(OH) in order to produce both light oil and a raw material for iron making called iron ore/carbon composite (IOC). In the proposed method the carbonaceous resource is expected to fill up the layered pore space of 0.8 nm wide which was formed by the dehydration of FeO(OH) up to 3000℃. Then, the carbonaceous resource in the pore space can catalytically be cracked to produce light oil in high yield over 400℃. The resulting low-grade iron ore consisting of Fe_2O_3 and containing coke in the pore space, can be utilized as the IOC realizing rapid reduction of iron ore. In this study it was clarified that the method was more effective for thermoplastic materials such as heavy oils and waste plastics. For non-thermoplastic materials such as low-rank coals, it was shown that hot press pretreatment or hot solvent pretreatment could enhance the contact between the carbonaceous materials and iron ore, resulting in the production of higher-quality IOC.
