Elemental Iron as a Tar Breakdown Catalyst in Conjunction

 · Metallic iron as a catalyst for tar cracking in biomass gasification has been investigated. Based on previous studies showing that iron must be in its elemental form to catalyze the tar breakdown reactions thermodynamic calculations suggest the existence of an operating window where iron is neither oxidized nor contaminated by carbon deposits. A straightforward biomass gasification model has

Preparing high-purity iron by direct reduction‒smelting

 · A new process for preparing high-purity iron (HPI) was proposed and it was investigated by laboratory experiments and pilot tests. The results show that under conditions of a reduced temperature of 1075°C reduced time of 5 h and CaO content of 2.5wt a DRI with a metallization rate of 96.5 was obtained through coal-based direct reduction of ultra-high-grade iron concentrate.

Rules of Assimilation of Single Ore and Mixed Ores

Assimilation behaviors of 7 kinds of iron ores from Australia Brazil India South Africa and China were evaluated and analyzed. On the basis of that four ore blending principles were proposed and seven groups of iron ore powder blending schemes were designed. The ores of different types or from different places are shown apparently different in assimilation.
