摘要: Abstract The cobalt-containing Y-zeolite catalysts were prepared by excess water (EW), ionexchange (IE) and carbonyl impregnation (CI) methods. activity selectivity in CO hydrogenation is explained terms of the acidity modification metal distribution. Characterization electron paramagnetic ferromagnetic resonance spectroscopy TPSR was good agreement with catalytic property. Temperature programmed surface reaction (TPSR) for methane formation proposed as a tool to determine location species, especially CI catalysts.
