| 英文摘要 | the coupling transformation of n-hexane and methanol over hzsm-5 has been investigated with a pulse-reaction system. in the temperature range of 400-500 degrees c, kinetic data was collected and reaction order was determined. compared with the pure n-hexane cracking, the increased rate constant and the lowered apparent activation energy clearly demonstrate an improvement of n-hexane activation using methanol as co-reactant and an increased contribution of faster bimolecular mechanism to the n-hexane transformation due to methanol introduction. similarly, the results of coupling transformation performed over hzsm-5 with different al content further confirm the transition between reaction mechanisms of n-hexane on account of the introduction of methanol. moreover, the further investigation suggests that the enhancement of n-hexane activation and the change of reaction mechanism are attributed to the presence of intermediate species evolved from methanol. thus, a proposed reaction pathway of n-hexane activation with methanol as co-reactant was put forward. |
