Carbon deposition from biotar by fast pyrolysis using the chemical vInfiltration process within porous low-grade iron ore for iron-making

Carbon deposition from biotar by fast pyrolysis using the chemical vInfiltration process within porous low-grade iron ore for iron-making

This paper presents a technology for iron-making using biomass and a low grade iron ore by implementing chemical vapor infiltration (CVI) for the tar carbonization process. In this process, tar vapor from pyrolysis of biomass was infiltrated within a porous ore and carbon deposition occurred on th...
