摘要: This paper describes fundamental experiments of a new biomass ironmaking that employs low-grade iron ore and woody for promoting the direct reduction, FeO + C = Fe CO, in which dehydrated, porous limonite was filled with carbon deposited from tar, biotar. In our experiments, three types ores containing different amounts combined water (CW; 1.6, 3.8, 9.0 mass %) were first dehydrated at 450 °C to make them then heated pine tree 500−600 gasification tar vapor generated decomposed deposit within/on ores. The dehydration treatment made by removing CW significantly increased their Brunauer−Emmett−Teller (BET) specific surface areas porosities. second decomposition vapor, changed into char, reducing gas; biotar carbonized within Interestingly, the...
