چکیده
Abstract Chemical-looping combustion (CLC) is a highly efficient CO 2 separation technology with no direct contact between air and fuel. A metal oxide used as an oxygen carrier (OC) acts in dual fluidized bed tool supplies the fuel oxygen, which oxidation medium causes to H O. The use of solid fuels, especially biomass, focus current investigations. OC plays key role, because it must meet special requirements for are different gaseous fuels. ash content, reaction mechanisms, increased abrasion make research into new types essential. Preliminary testing before their larger plants regarding suitability recommended. For this reason, work shows design results laboratory reactor, was planned built fundamental investigation OC. Designed transient bed, equipped its own conveying system situ sampling, intended be particularly suitable cheap rapid pre-testing materials. During tests, shown that sampling device enables non-selective sampling. Different were tested under various operating conditions, ability convert fuels could quantified. indicate can sufficiently investigated recommend operation plants.

Effect of support on reactivity and selectivity of Ni- based oxygen carriers for Chemical-Looping Combustion
Different Ni-based oxygen carriers were prepared by dry impregnation using -Al2O3 as support. The reactivity, selectivity during methane combustion, attrition rate and agglomeration behaviour of the oxygen carriers were measured and analyzed in a termogravimetric analyzer and in a batch fluidized bed during multicycle reductionoxidation tests. * Manuscript

Chemical-Looping Combustion (CLC) is an emerging technology for CO2 capture because separation of this gas from the other flue gas components is inherent to the process and thus no energy is expended for the separation. Natural or refinery gas can
متن کاملSolid waste management of a chemical-looping combustion plant using Cu-based oxygen carriers.
Waste management generated from a Chemical-Looping Combustion (CLC) plant using copper-based materials is analyzed by two ways: the recovery and recycling of the used material and the disposal of the waste. A copper recovery process coupled to the CLC plant is proposed to avoid the loss of active material generated by elutriation from the system. Solid residues obtained from a 10 kWth CLC proto...
