1-15　Preparation of Ni catalysts supported on hydroxyapatite with different Ca/P and their activity for decomposition of biomass tar at low temperature

Abstract

In this study, we investigated the catalytic activity of Ni catalysts supported on hydroxyapatite with different Ca/P (Ca/P=1.4 and 1.8 ) for decomposition of biomass tar. The Ni /HAP catalysts (Ni/HAP14 and 18) showed the high catalytic activity for decomposition of biomass tar derived from pyrolysis of Japanese Cypress. Furthermore, The introduction of steam during biomass pyrolysis reduced carbon deposition and increased H₂ yield. Specifically, the higher Ca/P was effective to proceed the steam gasification of deposited carbon.
