| 摘 要： | 对环境的越来越多的关注，直接导致了燃料油的标准变得越来越严格．柴油中太高含量的芳香烃（尤其是多环芳烃）将导致其密度增大，颜色变暗，尾气中颗粒含量上升，燃烧性能下降．通过传统的深度加氢装置使芳香烃达到饱和也不能有效的提高十六烷值（因为深度加氢的产物-环烷烃同样具有较低的十六烷值）．而环烷烃的开环产物（烷基苯、烷基环己烷、烷基环戊烷、烷烃等）却具有相对较高的十六烷值，这就使得芳香烃饱和加氢后所得环烷烃的进一步开环变得重要起来。 |

| Abstract: | Coupled hydrogenation and selective ring-opening of tetralin was investigated over Pt/Y and Pt/USY catalysts at hydrogen pressures(4.0 MPa).The results indicated that hydrogenation of tetralin could be achieved over both Pt/Y and Pt/USY,and the acid strength of the supports played an important role in the ring-opening reactions.Compared to USY,Y was a better support for ring-opening,due to its relatively weak acid strength.In conclusion, a support with mild acid strength would favor the ring opening of tetralin. |
| Keywords: | Tetralin Decalin Hydrogenation Ring-opening USY |
