Guaiacol hydrodeoxigenation over carbon supported nickel phosphide (Ni2P/C) – the effect of carbon support on synthesis and catalytic activity

Résumé

In this work, 2 different carbon materials (carbon nanotubes – CNT; mesoporous carbon – MC) were used as the support of Ni2P and the obtained Ni2P/C catalysts were employed in guaiacol HDO reaction (300 °C and 30 bar (H2) in batch reactor). Samples were prepared in such a way to present the same number of Ni atoms per surface area of support (9.3% wt. for CNT and 29.3% wt. for MC) and were characterized by TPR, ICP-OES, DRX, HR-TEM, and CO chemisorption and desorption (CO TPD). Catalysts characterization data showed that each support has a different interaction force with the supported material and if affects both the reduction and the hydrotreating nature of Ni2P. 9.3Ni2P/CNT presented a lower reduction temperature and a more hydrogenating nature while 29.3Ni2P/MC had a higher reduction temperature and a more hydrotreating nature. Moreover, the addition of 1% Pd to each Ni2P/C precursor led to a lowering in Ni2P synthesis temperature and a suppression in guaiacol direct hydrogenation
