Abstract. Coldbonded pellets, to which a new type of inorganic binder was applied, were reduced by H 2 –CO mixtures with different H 2 /CO molar ratios (1:0, 5:2, 1:1, 2:5, and 0:1) under various temperatures (1023, 1123, 1223, 1323, and 1423 K) in a thermogravimetric analysis apparatus. The effects of gas composition, temperature, and binder ratio on the reduction process were studied, and ...
