Plantwide control of chemical looping combustion
2012 American Control Conference (ACC), 2012Passive systems theory is used to develop a general procedure to design the control structure of chemical process networks. A natural storage function, derived from the second law of thermodynamics, is the basis for passivity-based control design. The inventory control laws are implemented locally and individual units become passive.

Geopolymer composites for chemical looping combustion
Fuel, 2018Chemical looping combustion allows a simple separation of CO2 during the combustion of fossil fuels, thanks to the use of regenerable oxygen carriers. In this work, novel materials containing manganese and iron/manganese oxides have been developed via geopolymerization, and characterized in thermogravimetric apparatus and fixed bed reactor.

Abstract The production of hydrogen from methane via two chemical looping reforming (CLR) processes was simulated and thermodynamically analysed, one process being the conventional CLR process, the other being a CO2 sorption enhanced process. The aim of the work was to identify suitable operating conditions for obtaining an optimum hydrogen gas ...

Thermal management for chemical looping systems with chemical production
Chemical Engineering Science, 2020Abstract Chemical looping technology is a promising pathway to realize a clean production of value-added chemicals with less energy penalty. Its core concept, utilizing heat storage in the cycled solid materials to maintain an efficient operation, needs further confirmation. Here, a combined thermal management method is firstly proposed to achieve an
