NU-Iron, A Fluidized-Bed Reduction Process

The sticking of iron ore during reduction by hydrogen in a fluidized bed

“…A number of pilot and semiindustrial size plants have been built (1)(2)(3) of which the largest installation currently in operation is the H.I.B. process of u.s. Steel in Venezuela (4).…”

Recent status of fluidized bed technologies for producing iron input materials for steelmaking

“…The processes H-Iron (Squires & Johnson, 1957) and Nu-Iron, later called HIB (Reed, Argarwal, & Shipley, 1960) were the pioneering developments though they did not succeed in achieving industrial maturity.…”

A Preliminary Evaluation of the Use of High-Temperature Process Heat as Part of a Total Nuclear-Energy Source

“…C + H20(v) = CO + Hz, Q = 32 kcal; (12) HzO(£) = H2O(v), Q = 1 0 k c a l; (13) CO + Hz V) = (02 + Hz, Q = -10 kcal; (14) C + 02(air) = COZ, Q = -94 kcal. (15) Reaction (12) is the primary gasification step.…”
