Abstract

The development of catalysts for the decomposition of biomass tar is one of the major challenges for the low-temperature gasification of biomass. In this study, Ni-loaded hydroxyapatite (HAP) catalysts were prepared for the tar decomposition at low temperature, 450°C. The effects of Ca/P in HAP on the catalytic activity of Ni/HAP catalysts for the tar decomposition were investigated because the catalytic activity of the HAP is known to vary with its Ca/P. The results indicate that the Ni-loaded HAP with higher Ca/P showed higher catalytic activity to decompose of both phenol used as a model tar and actual biomass tar.
