摘　　要：以辛癸酸甘油酯为模型化合物,采用高压流动反应装置考察辛癸酸甘油酯在金属硫化物加氢催化剂CoMo/γ-Al2O3,NiMoP/γ-Al2O3,NiMoP/γ-Al2O3-HUSY和贵金属双功能催化剂Pt/SAPO-11催化剂上的加氢脱氧反应规律。结果表明:辛癸酸甘油酯在加氢催化剂上的反应包括加氢饱和、脱羧、异构化和裂化反应,主要产物为烷烃;采用Pt/SAPO-11催化剂的催化加氢产物中异构化烷烃比例明显提高,脱羧反应和裂解反应得到明显抑制。The hydrodeoxidation reaction of decanoyl/octanoyl-glycerides on CoMo/γ-Al2O3 , NiMoP/γ-Al2O3, NiMoP/γ-Al2O3HUSY and bi-functional catalysts of Pt/SAPO-11 was investigated in flow micro-reactor with high pressure. The research results indicate that the main reaction from the hydrodeoxygenation of deeanoyl/oetanoyl-glycerides on the catalysts inelude hydrogenation saturation, deearboxylization, isomerization and hydrocracking. The main product is alkane. On the Pt/ SAPO-11 catalyst, the products composition of HDO from decanoyl/octanoyl glyceride possesses high iso-alkanes content, which indicates that the decarboxylization and hydrocracking reactions are obviously restrained.
