Abstract
|
Reports
a study of two nickel based oxygen transfer materials (OTMs) supported on alumina
and zirconia for potential use in chemical looping reforming.
Zirconia supported (Ni–Zr) OTM exhibited good redox activity and stability during multiple CH4 reduction-air oxidation cycles in a thermogravimetric unit. Alumina supported OTM (Ni–Al) showed increasing degree of reduction during the first 12 cycles, due to reduction of NiAl2O4 species, followed by stable performance during the last 8 redox cycles. Hydrogen was produced by methane decomposition catalyzed by Ni on both OTMs. |
