Integrated Pyrolysis–Tar Decomposition over Low-Grade Iron Ore ...

Feb 3, 2017 ... In this study, we investigated the effect of coal–biomass co-pyrolysis in integrated pyrolysis–tar decomposition over low-grade iron ore. Combined coal–biomass with biomass blending ratios (BBRs) of 0, 25, 50, 75, and 100% were studied by thermogravimetric analysis. A kinetic study on the co-pyrolysis...
