Chemical looping combustion of liquid fuels
Kapitel i bok, 2015
Up to this point comparably little research has been conducted concerning chemical looping combustion of liquid fuels. This article provides an overview of the field and discussion of the subject. It is shown that basic oxygen carrier materials such as NiO, CuO, Mn3O4 and FeTiO3 perform in similar way when liquid fuels are used as when gaseous fuels are used, and that the choice of fuel feeding system is very important and will be different for different kinds of liquid fuels. Light liquid fuels can be vaporized before being fed to a reactor systems similar in design to those used for gaseous fuels. Heavy liquid fuels have sufficiently high boiling point for coking to occur before complete vaporization which makes fuel feeding more complicated. It is concluded that chemical looping combustion of liquid fuels is feasible and that the most likely application is the generation of heat and power with CO2 capture using heavy oils or bitumen as fuel. Niche applications involving other kinds of liquid fuels are also briefly discussed.
