The use of ilmenite as oxygen carrier with kerosene in a 300W CLC laboratory reactor with continuous circulation
Conference contribution, 2012

An ilmenite oxygen carrier was tested in a laboratory scale chemical-looping reactor with a design thermal capacity of 300 W. Ilmenite is a mineral iron-titanium oxide, which has been used extensively as an oxygen carrier in CLC. Two different kinds of fuels were used, a sulfur-free kerosene and one that contained 0.57 mass-% sulfur. Both fuels were continuously evaporated and di-rectly fed into the chemical-looping reactor. Experiments were conducted for 50 h with the sulfur-free kerosene and for 30 h with the sulfurous kerosene. CO2 yields above 99% were achieved with both types of fuel. It seems that a significant and lasting improvement in the oxygen carrier’s reactivity was achieved by using sulfurous kerosene. No evidence of sulfur was found on the particles’ surface.
