Application of Biomass to the Direct Reduction Process

In this paper,charcoal and anthracite were selected as reducing agent to study the influence of reduction temperatures,C/O,reduction time on metallization rate.In addition,the effect of reduction by charcoal and anthracite had been compared by using XRD analysis.The results show that the charcoal has similar reduction effect with anthracite when used for direct reduction process.Under same conditions（temperatures,C/O and time）,the effect of charcoal and anthracite on metallization rate have less difference.It is feasible that using charcoal as reducing agent in the direct reduction process.When temperature is 1 200 ℃,C/O is 0.7,and better reduction time is 20 min,using charcoal as reducing agent can achieve more than 80% metallization rate.
