“…The mechanism of coal gasification to form syngas is usually through Boundouard reaction and carbon gasification reactions described by reactions (6) and (8), respectively. The gasified syngas from coal is combusted by oxygen carriers in the fuel reactor, the syngas combustion is described as reaction (11) However, IGCC system as a post-combustion technology requires separating CO 2 with additional recovery system that energy penalty is estimated 17.5% resulted in declining of electricity generation efficiency from 46 to 39.3% HHV (Amelio et al, 2007). Chemical looping is proposed to be combined with IGCC for syngas combustion to reduce energy penalty for CO 2 capture, and the exergetic power efficiency was estimated as high as 48.7% by employment of Fe 2 O 3 as oxygen carrier in chemical looping combustion (Anheden and Svedberg, 1998).…”

Chemical looping is a novel energy technology that undertakes inherent CO 2 capture and has better energy efficiency than existing CO 2 capture technologies. Metal oxides (also known as oxygen carriers) are applied for the chemical looping process in place of air to offer oxygen for fuel combustion, thus enhancing CO 2 purity in the effluent stream. This article introduces the major aspects of chemical looping technology, including the oxygen carrier, reactor and fuel. Fe-, Ni-and Cu-based metal oxides were found to be suitable oxygen carriers for the chemical looping process based on the evaluation indexes of oxygen capacity, cost, reactivity, and mechanical strength. The modification of oxygen carriers by supporting materials is the typical research regime for enhancing mechanical strength and reactivity. The reactor systems currently used for the chemical looping process include fluidized and moving bed reactors. Fluidized bed reactors are well developed for gaseous fuel combustion applications, while moving bed reactors operated with a counter-flow mode between the solid fuel and oxygen carriers would enhance combustion efficiency, and reduce the operating solid inventory of oxygen carriers. Gaseous fuels, including natural gas and syngas gasified from coal, could achieve complete fuel conversion and high CO 2 yield for different combinations of oxygen carrier and reactor system. Gasification of solid fuels, including coal, petroleum coke and biomass in the fuel reactor, is a critical step that might reduce overall combustion efficiency. To improve solid fuel combustion and CO 2 yield, modification of the reactor design or operational conditions are necessary for the combustion of solid fuels by a chemical looping process.

This paper presents a summary of technical-economic studies. It allows evaluating, in the French context, the production cost of electricity derived from coal and gas power plants with the capture of CO 2 , and the cost per ton of CO 2 avoided. Three systems were studied: an Integrated Gasification Combined Cycle (IGCC), a conventional combustion of Pulverized Coal (PC) and a Natural Gas Combined Cycle (NGCC). Three main methods were envisaged for the capture of CO 2 : pre-combustion, post-combustion and oxy-combustion.For the IGCC, two gasification types have been studied: a current technology based on gasification of dry coal at 27 bars (Shell or GE/Texaco radiant type) integrated into a classical combined cycle providing 320 MWe, and a future technology (planned for about 2015-2020) based on gasification of a coal -water mixture (slurry) that can be compressed to 64 bars (GE/Texaco slurry type) integrated into an advanced combined cycle (type H with steam cooling of the combustion turbine blades) producing a gross power output of 1200 MWe.

“…Because a greater quantity of CO 2 is produced by coal gasification than by SMR for each unit of produced hydrogen, one might expect a greater conversion efficiency reduction to capture the CO 2 . On the other hand, membrane technology could reduce the efficiency loss from CO 2 capture (Amelio, Morrone, Gallucci, & Basile, 2007).…”
