Effect of support on the NiMo phase and its catalytic hydrodeoxygenation of triglycerides

The support effect on the NiMo phase was studied by using two kinds of mesoporous materials, SAPO-11 and Al2O3, which were applied on the hydroconversion of jatropha oil. It was shown that the amounts of strong acidic sites of the NiMo/SAPO-11 catalyst (610 mu mol/g) was higher than that of NiMo/Al2O3 catalyst (190 mu mol/g), resulting into the different NiMo phase formed on the respective SAPO-11 and Al2O3. The NiMo/SAPO-11 catalyst with larger NiMoO4 and MoO3 sulfided phases showed higher selectivity for decarboxylation reaction (41.2%), while the NiMo/Al2O3 catalyst with more Mo4+ polymeric octahedral sulfided phases led to main hydrodeoxygenation products (62.5%).
