The thermodynamic feasibility of a new process scheme combining chemical looping combustion (CLC) and combined reforming (CR) of propane (LPG) is studied in this paper. The study of CLC of propane with CaSO(4) as oxygen carrier shows thermodynamic feasibility in temperature range (400-782.95 degrees C) at 1 bar pressure. The CO(2) generated in the CLC can be used for combined reforming of propane in an autothermal way within the temperature range (400-1000 degrees C) at 1 bar pressure to generate syngas of ratio 3.0 (above 600 degrees C) which is extremely desirable for petrochemical manufacture. The process scheme generates (a) huge thermal energy in CLC that can be used for various processes, (b) pure N(2) and syngas rich streams can be used for petrochemical manufacture and (c) takes care of the expensive CO(2) separation from flue gas stream and CO(2) sequestration. The thermoneutral temperature (TNP) of 702.12 degrees C yielding maximum syngas of 5.98 mol per mole propane fed, of syngas ratio 1.73 with negligible methane and carbon formation was identified as the best condition for the CR reactor operation. The process can be used for different fuels and oxygen carriers. (C) 2010 Elsevier Ltd.

In this technique contact of air and fuel for combustion is restricted by providing oxygen through oxygen carrier (DC). The functional efficiency of CLC process mainly depends on the ability of oxygen carrier and it's reactivity, which undergoes repeated oxidation and reduction cycles. Nanostructure metal oxides have shown great potential application in the field of chemical looping combustion due to their high surface to volume ratio and enhanced structural properties. Synthesis technique of nanostructure metal oxides, their role as oxygen carrier, their reactivity with fuels along with their structural stability are reviewed herein. The contribution of various operating conditions on nanostructure oxygen carrier are considered in this review. These operating conditions and synthesis routes are summarized and classified according to metal oxides.</p>10aChemical looping combustion10aCO2 Emission10aMetal Oxide10aNanostructure10aOxygen Carrier1 aBadadare, Mansing, M.1 aAdbale, Naina, M.1 aKhomane, Ramdas, B.1 aKale, Ganesh, R.  uhttps://library.ncl.res.in/content/nanostructure-oxygen-carrier-used-chemical-looping-combustion-process-review
