Ni-loaded hydroxyapatite containing various Ca/P ratios for use in the catalytic decomposition of biomass tar at low temperatures

Ni-loaded catalysts using hydroxyapatite (HAp) supports with various Ca/P ratios are promising biomass tar decomposition catalysts at low gasification temperatures ( i.e. , 450 °C), and that variations in the Ca/P ratio of the HAp support allow tuning of the Ni dispersion state and catalytic activity.
