Abstract
The composition and phase structure of high-percentage (>50 wt % Ni) n ickel-alumina catalysts for methane decomposition at 550 degrees C was studied. The main stages of catalyst preparation (precipitation, dryi ng, thermal decomposition, reduction) are analyzed. The dependence bet ween the extent of catalyst coking and the alumina content was found t o exhibit a maximum at similar to 10 wt % Al2O3.
