  • Coupled biomass (lignin) gasification and iron ore

    Abstract Aiming at a novel application of biomass, coupled biomass gasification and iron ore reduction was investigated and demonstrated in this work through pyrolysis/gasification of iron ore–lignin pellets (ILP) at 1093–1333 K The solid, liquid and gaseous products were analyzed by XRD, SEM, chemical analysis, GCMS, GC and TGFTIRIn 1943, E W Davies and coworkers demonstrated the process using an experimental shaft furnace Commercial operation started in the 1950s in Sweden using verticalshaftkilns for firing the pellets Plant capacities were between 10,000 and 60,000 tons/ year [1] The world installed pelletizing capacity is currently estimated to be 4807 million tons/year [2] As shown in Figure 1 , ChinaIron Ore Pelletizing Process: An Overview IntechOpenElectrolysis of iron ore has been demonstrated at the laboratory scale, producing metallic iron and oxygen as a coproduct Current status The EU ULCOS project examined the prospects for electrolysis based ironmaking through their ULCOTWIN initiative • The Siderwin project, being led by ArcelorMittal, is looking at using low temperature electrolysis using a waterbased electrolyte TheFact sheet Electrolysis in ironmaking Steel
