The growing economy and changing lifestyle have increased the demand for modern energy, like electricity. Globally 1.3 billion people are without access to electricity. In India, 289 million people do not have access to electricity. Decentralized distributed power generation using renewable...

We have derived an analytic model describing the interior temperature difference as a function of the load current of a thermoelectric generator (TEG); we have also proposed a method to extract the intrinsic and extrinsic Seebeck coefficients and resistances of TEG using experimental...

A novel methanol-based power system with Chemical-Looping Combustion (CLC) is proposed in this paper. CLC system is a promising approach to greatly decrease the energy penalty for CO2 removal, where iron oxides circulate between two reactors and an inherent CO2 separation occurs. The combustion...

Carbon capture for storage or reuse is seen as one possibility to lower the emissions of anthropogenic CO2. Chemical-looping combustion (CLC) is a promising second generation technique to capture CO2 from thermochemical fuel conversion processes, such as combustion for power generation. The...

The performance of coal fly-ash based oxygen carriers for chemical looping combustion of synthesis gas has been investigated using both a thermogravimetric analyser and a packed bed reactor. Oxygen carriers with 50wt% active metal compounds, including copper, nickel and iron oxides, supported on...

Oxygen-carrier materials for chemical-looping with oxygen uncoupling (CLOU) must be capable of taking up and releasing gas-phase O2 at conditions relevant for generation of heat and power. In principle, the capability of a certain material to do so is determined by its thermodynamic properties....

This study describes the design and operation of a 100kW chemical-looping combustor for solid fuels. Six experiments of continuous operation, varying between 8 and 32min in length, have been conducted. The fuels investigated were a Mexican petroleum coke and a bituminous coal from Cerrejón in...

To enhance CO2 capture, nanostructured bimetal oxide (i.e., CuO–NiO) dispersed on chabazite were used as an oxygen carrier for the chemical-looping combustion (CLC) of a syngas (CO (35%) and H2 (25%) balanced with N2). At the temperature range of 973–1173K, desired contact times (4min) for...

Chemical-looping combustion (CLC) is a novel and promising combustion technology with inherent separation of the greenhouse gas CO2. This paper focuses on the design and thermodynamic evaluation of an integrated gasification combined-cycle (IGCC) process using syngas chemical looping (SCL)...

The objective of this work is to study the performance of the oxygen carrier in a packed bed with periodic switching between oxidizing and reducing conditions. In this paper the performance of CuO/Al2O3 as the oxygen carrier in a packed bed reactor with syngas as the fuel are investigated, while...
