We studied the effect of H2 addition to atmosphere on reduction of carbon composite iron oxide pellets. Cokes was mixed with reagent grade hematite in the mass ratio of one to four (COKE-a) or nine (COKE-b) together with Bentonite of 1 mass% as a binder. Carbon composite pellets using cokes were prepared by handrolling. The formed pellets were reduced from room temperature to 1273 K at 10 K min-1 in the inactive gas (Ar or N2) atmosphere or the inactive gas atmosphere containing 10 vol% H2. From variations of gas flow rate and weight loss curve of COKE-a in the inactive gas atmosphere containing 10 vol% H2, it was found that the reduction of iron oxide started from 573 K by the effect of 10 vol% H2 and accelerated from 1273 K by the effect of not 10 vol% H2 but cokes. On the other hand, in case of COKE-b, the weight drastically decreased from 1273 K by the effect of 10 vol% H2. Finally, the UH2(H2 reaction ratio) increased with decreasing the RC(coke reaction ratio) using COKE-b.
