Chemical-looping combustion (CLC) is a technology with inherent separation of the greenhouse gas CO2. The technique involves use metal oxide as an oxygen carrier, which transfers from air to fuel. Two reactors are used in process: (i) fuel reactor where reduced by reaction fuel, and (ii) oxidized air. possibility using oxides Cu, Co, Mn, Ni carriers was investigated. Particles were prepared deposition on γ-Al2O3 particles so-called dry impregnation. reactivity carrier evaluated...
Chemical-looping combustion (CLC) is a technology with inherent separation of the greenhouse gas CO2. The technique involves use metal oxide as an oxygen carrier that transfers from air to fuel. iron has been investigated. Particles composed 40−80 wt % Fe2O3, together Al2O3, ZrO2, TiO2, or MgAl2O4, have prepared by freeze granulation. sintered at different temperatures in range 950−1400 °C, and particles 0.125−0.180 mm diameter obtained sieving. reactivity oxygen-carrier evaluated laboratory...
A concept for combined hydrogen and power production from natural gas with CO2 capture is presented. The process involves the use of a metal oxide in fluidized bed reactors; reduced by mixture steam fuel reactor oxidized air reactor. partially reactor, resulting CO2, H2, H2O, CO exit. If no hydrocarbons are present this stream, it can be sent to water shift get an undiluted stream H2. product contains mostly N2 some unreacted oxygen. oxidation reaction exothermic heat reactor; used maintain...
Chemical-looping combustion (CLC) and chemical-looping reforming (CLR) involve the use of a metal oxide as an oxygen carrier which transfers from air to fuel. Two interconnected fluidized beds, fuel reactor, reactor are used in both processes. In is oxidized by oxide, reduced back original phase. CLC, high conversion CO2 H2O required whereas only partial oxidation desired CLR. Oxides Ni, Cu, Fe, Mn supported on SiO2 MgAl2O4 were prepared dry impregnation investigated under alternating...
For combustion with CO2 capture, chemical-looping inherent separation of is a promising technology. Two interconnected fluidized beds are used as reactors. In the fuel reactor, gaseous oxidized by an oxygen carrier, e.g., metal oxide particles, producing carbon dioxide and water. The reduced carrier then transported to air where it back its original form before returned reactor. Carbon deposition on oxygen-carrier particles was investigated assess whether could have adverse effects process....
Chemical-looping with oxygen uncoupling (CLOU) is a developing technology, which allows for inherent separation of carbon dioxide during combustion gaseous and solid fuels. In contrast to the related chemical-looping technology (CLC), where or gasified fuels react directly carrier materials, CLOU utilizes carriers capable releasing oxygen, provided appropriate thermal conditions exist in fuel reactor, whereupon reacts released oxygen. The are thereafter regenerated by oxidation air reactor....
Chemical-looping combustion (CLC) is a technology with inherent separation of the greenhouse gas CO2. The technique involves use metal oxide as an oxygen-carrier, which transfers oxygen from air to fuel. Fe2O3 on MgAl2O4 support was examined, and particles diameter 125−180 μm were prepared by freeze-granulation. reactivity evaluated in fluidized-bed reactor, where atmosphere periodically changed. Reduction performed 50% CH4 H2O, while oxidation 5% O2. sintering temperature ratio oxide/inert...
