摘要：

The catalytic hydrodeoxygenation reaction (HDO) of palm oil was studied with sulphided Ni-Mo/Al2O3 as catalyst in a fixed bed reactor. Besides, the reaction heats of the three HDO paths of direct hydrodeoxygenation, hydrodecarboxylation and hydrodecarbonylation were calculated. The influences of reaction conditions on the conversion of palm oil, deoxidation and three HDOs were investigated. The results demonstrated that hydrogenation and three HDOs of palm oil were all the exothermic reactions. Among the three HDOs, the direct hydrodeoxygenation released maximum heat and the hydrodecarbonylation released the least heat. Increase of reaction temperature was in favor of hydrodecarboxylation, but not favor of the other two HDO paths. The direct hydrodeoxygenation and hydrodecarboxylation were enhanced more than hydrodecarbonylation as the reaction pressure increased. When LHSV was increased, the fraction of hydrodecarbonylation was increased, while the fractions of direct hydrodeoxygenation and hydrodecarboxylation were decreased. The C15-C18 paraffins were the main products from HDO of palm oil.
