“…Preliminary economic assessments have suggested that CLC is a promising combustion process with high efficiency and low-cost CO 2 capture. However, commercialization of CLC mainly depends on the availability of excellent OCs. ,,,,− Almost all experimental data now available are from specific reactor types with specific OCs, and operating time may not be sufficient to ensure the quality of the OCs and the long-term performance of the CLC system over many cycles. Design optimization, continuous operation, detailed engineering, and cost analysis at larger scales are still needed.…”

The world-wide consumption of natural gas (NG) and other fossil fuels (e.g., coal and crude oil) is ever increasing. However, most CO 2 resulting from either NG combustion or other processes is released into the atmosphere without capture. Chemical looping combustion (CLC) is a two-step combustion technology for power and heat generation with inherent CO 2 capture, using either gaseous fuels or solid and liquid fuels. A previous review focused on CLC of solid fuels or CLC of all types of fuels but did not give an in-depth and specific discussion of gaseous fuel CLC systems. China is one of the largest consumers of NG, coal, and crude oil in the world, and it is essential to develop an alternative technology to take the place of gaseous fuel (e.g., NG) combustion. This Review summarizes recent research and development work on CLC using gaseous fuels, including a technological and economic assessment, types of oxygen carriers (OCs), reactor types, coke formation and OCs poisoning, efficiency and exergy analyses, and model development based on a literature survey. The plant efficiency of NG-CLC can be up to 52−60% (LHV), including CO 2 compression, based on calculations and simulations, which is about 3−5% more efficient than a NG combined cycle with CO 2 capture. Ni-based materials have been widely developed and applied for NG-CLC because of its fast kinetics for methane conversion. CuO−Cu 2 O/Cu, Mn 3 O 4 −MnO, and Fe 2 O 3 −Fe 3 O 4 are typical OCs with high selectivity toward CO 2 and H 2 O. The operating conditions are closely dependent on reactor configurations, hydrodynamics, mass and heat balances, and characteristics of the OCs in the system. CLC and other CO 2 capture technologies are also compared in the present Review, which has rarely been investigated previously. From simulation and process analysis, a conceptual design of a NG-CLC power plant of thermal input 655 MW th is conducted to clarify its technological advantages and economic benefits compared to other power generation processes. The air reactor, fuel reactor, and OCs do not impose significant economic barriers for scale-up and commercialization of CLC.

This paper reports latest advancement on oxygen carriers (OCs) and effect of particle size from micro-to nanoscale in chemical looping combustion (CLC). CLC is basically a carbon capture and storage technology with the objective to reduce carbon dioxide emission from fossil fuel-based power plants, and it has the potential to reduce the global warming. Attention has been drawn toward utilization of nanosize-based oxygen carrier for bulk application. CLC is a novel technology for combustion of fossil fuels that avoids dilution of carbon dioxide (CO 2 ) with flue gases. Performance of CLC system depends upon redox reactivity and stability of oxygen carrier particles at high operating temperature. Oxides of metals like nickel, iron, copper, and mixed metals have also been discussed. Tendency of discussed nano-OC to agglomerate and stability at high temperature can be addressed by the use of suitable inert support materials. Reactivity of oxygen carrier increases with decreasing particle sizes from micro-to nanosize. Recent developments in nanosized oxygen carriers can be exploited for application. The challenges associated with nanosize oxygen carriers are stabilization and agglomeration at temperature above 600 °C. Different techniques have been proposed and investigated to overcome challenges. Various metal/metal oxide pair has been evaluated for its oxygen bearing capacity, stability, and resistance to agglomeration. Stability and agglomeration of nanosize oxygen carrier at temperature above 700 °C is an open issue.

“…The preparation of nanostructured materials has received considerable attention owing to their unique properties and interesting potential applications [4][5][6][7][8][9][10]. Metal oxide nanomaterials are interesting solids due to their surface acid-base properties and oxidation-reduction potentials and hence they constitute the largest family of heterogeneous catalysts [11][12][13][14][15][16]. Several transition metal oxides exhibit the oxidation-reduction behavior due to the ease with which they can be used as an oxidizing agent and then readily be generated [17][18][19][20][21].…”

CuO-NiO nanocomposite catalysts were synthesized by an oxalate precipitation route. The basicity of the catalysts was measured using adsorption-desorption of acetic acid. The catalytic conversion of isopropanol to acetone was carried out in a conventional fixed bed flow type reactor at 200°C using N2 as a carrier gas. The results indicated that, the addition of NiO to CuO greatly enhanced the electrical conductivity via the creation of new charge carriers (Cu + -Ni 3+ ). In addition, the results revealed that the catalyst containing 30 wt.% NiO calcined at 400°C possesses the highest catalytic activity with 98% conversion and 100% selectivity to acetone. The remarkable catalytic performance of the synthesized catalysts is attributed to the decrease of the energy gap, the increase in the concentration of charge carries (Cu + -Ni 3+ ), and to the creation of more weak and intermediate basic sites.
