| 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/7-A1203 ,NiMoP/rAl203 ,NiMoP/rAl203-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、脱竣、异构化和裂化反应，主要产物为烷烃;釆用Pt/ sapo-11催化剂的催化加氢产物中异构化烷烃比例明a提高，脱羧反应和裂解反应得到明显抑制。 |

| Abstract: |
| The hydrodeoxidation reaction of decanoyl/octanoyl-glycerides on CoMo/y -Al2 03 , NiMoP/y-Al203，NiMoP /y-A1203-HUSY 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 decanoyl/octanoyl-glycerides on the catalysts include hydrogenation saturation, decarboxylization, 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. |
