Chemical-Looping Combustion with Liquid Fuels

Conference poster, 2012

A project devoted to establishing chemical-looping combustion with liquid fuels currently being conducted by Chalmers University of Technology with support from Saudi Aramco is presented. The ultimate goal of the project is to develop technology capable of utilizing and processing heavy residual oils with inherent CO2 capture. Heavy oil residues are intermediate products from oil refineries. Some of those residues can be blended with lighter oil fractions to produce fuel oils, while others are waste products. Heavy oil residues are highly viscous at ambient temperature and contain high amounts of impurities such as sulfur, up to 6 wt-%, and metals, up to 1000 ppm. Using such fuel in a stationary combustion process with separation of CO2, namely chemical-looping combustion, might be an interesting option. The use of kerosene and fuel oil are intermediate steps in the upscaling of the process.
