Hydrogen production with CO2 capture by coupling steam reforming of methane and chemical–looping combustion (SR-CLC) — Use of an iron-based waste product as oxygen carrier burning a PSA tail gas
In this work it is analyzed the performance of an iron waste material as oxygen carrier for a chemical-looping combustion (CLC) system. CLC is a novel combustion technology with the benefit of inherent CO2 separation that can be used as a source of energy for the methane steam reforming process (SR). The tail gas from the PSA unit is used as fuel in the CLC system. The oxygen carrier behaviour ...
متن کاملCharacterization of natural copper ore in anthracite fueled Chemical-Looping with Oxygen Uncoupling (CLOU)
Chemical Looping with Oxygen Uncoupling (CLOU) is an advanced approach proposed for improving the utilization degree of solid fuels and speeding up the reaction rate in Chemical-Looping Combustion technology (CLC). In CLOU system, OC circulates between fuel reactor (FR) and air reactor (AR), providing gaseous oxygen for the combustion of fuels (in FR) and then being regenerated by absorbing gas...
متن کاملSyngas combustion in a 500 Wth Chemical-Looping Combustion system using an impregnated Cu-based oxygen carrier
Chemical-Looping Combustion (CLC) is an emerging technology for CO2 capture because separation of this gas from the other flue gas components is inherently to the process and thus no energy is expended for the separation. For its use with coal as fuel in power plants, a process integrated by coal gasification and CLC would have important advantages for CO2 capture. This paper presents the combu...
متن کاملEffect of Using Oxygen-Enriched Gas during Induration Process of Iron Ore Pellets Containing Solid Fuel
In this research, the effects of oxygen injection during the induration process were studied in order to improve the quality specifications and increase the rate of production of the iron oxide pellets. Several experiments were carried out in palletizing pilot plant in different conditions of oxygen injection. The results suggested that if only the extra oxygen was injected into the furnace in ...
متن کاملEffect of Fuel Gas Composition in Chemical-Looping Combustion with Ni-Based Oxygen Carriers. Part 1. Fate of Sulfur
Chemical-Looping Combustion (CLC) has been suggested among the best alternatives to reduce the economic cost of CO2 capture using fuel gas because CO2 is inherently separated in the process. As gaseous fuels it can be used natural gas, refinery gas or syngas from coal gasification, which may 2 contain different amounts of sulfur compounds, such as H2S and COS. An experimental investigation of t...
