Review of the Recent Chemical Looping Process Developments for Novel Energy and Fuel Applications

Abstract

Driven by the need to develop cleaner and more efficient energy systems, an extraordinary array of chemical-loopingbased process concepts have been proposed and researched over the past 10 years. An overview of these technology options, particularly those proposed/developed over the last 3 years, is presented in this paper. The focus, however, would be primarily on process-related aspects of such advanced chemical looping concepts for novel energy and fuels applications rather than aspects such as oxygen carriers, redox properties, and solid circulation/transport, which have been adequately covered in several other reviews.

Use of natural ores as oxygen carriers in chemical looping combustion: A review

“…Song et al (2009) investigated a CaSO 4 oxygen carrier by thermodynamic analysis and thermogravimetric analysis. It has been proved that CaSO 4 /CaS is an effective oxygen carrier in a CLC system (Moghtaderi, 2012). One main concern with CaSO 4 CLC operation is low fuel conversions (Ding et al, 2011;Zheng et al, 2014).…”

Co-Production of Olefins, Fuels, and Electricity from Conventional Pipeline Gas and Shale Gas with Near-Zero CO2 Emissions. Part I: Process Development and Technical Performance

“…Since only limited N2 mixes with the fuel CO2 capture is achieved by simply condensing water from the combustion exhaust, leaving a high purity CO2 stream behind. Then, chemical looping combustion with two different metal oxides was considered, which achieves indirect combustion of fuel gas by using a metal oxygen carrier such as iron-oxide (Fe2O3) in option three or nickel-oxide (NiO) in option four [40]. In either process, the combustion reaction takes place in the Fuel reactor with the oxygen provided by metal oxide while N2 is absent.…”

Hydrogen Production from Cyclic Chemical Looping Steam Methane Reforming over Yttrium Promoted Ni/SBA-16 Oxygen Carrier

“…However, SMR is energy intensive process and needs high level of capital investment that is not economically [18,19]. As an alternative method, chemical looping steam methane reforming (CL-SMR) process was proposed in order to overcome these drawbacks [20,21]. In this process the necessity of the gas separation is eliminated since the produced gas is not diluted with N 2 [22,23].…”
