Ni-substituted Sr-aluminates Sr1-xNixAl11.2+xNi0.8-xO19-δ (x = 0; 0.2; 0.4; 0.8) obtained by a precipitation method and calcined at 1200°C have been characterized by different physicochemical techniques and their catalytic properties have been tested in steam reformation of methane. It has been shown that substitution of Al3+ and/or Sr2+ by Ni2+ in the aluminate structure results in changes of phase composition, specific surface area, and reducibility of samples. It has been established that the samples are not completely reduced in the temperature range of 30-900°C. The Sr1-xNixAl11.2+xNi0.8-xO19-δ (x = 0; 0.2; 0.4) catalysts are active and stable in the steam reforming of methane at 700oC: residual amount of methane is (1.1±1.0) vol.%, while the Sr1-xNixAl11.2+xNi0.8-xO19-δ (x = 0.8) sample is rapidly deactivated by coking.
