A nanocrystal ZSM-5 zeolite comprising uniform single crystal particles of ∼100 nm in size was synthesised and characterised using XRD, ICP–AES, SEM, TEM, solid state MAS NMR and nitrogen physisorption techniques. The catalytic performance was tested in methanol to gasoline (MTG) conversion with a particular focus on the effect of reaction conditions, namely, temperature from 300 to 450 °C, pressure from 0.1 to 2.0 MPa and WHSV from 1 to 4 h⁻¹. Temperature showed a significant impact. At temperatures ≤350 °C, methanol conversion did not complete while the catalyst was deactivated more rapidly. Increasing temperature to above 375 °C saw complete methanol conversion and durable catalyst activity. Further increasing the reaction temperature to above 400 °C reduced gasoline yield. Pressure mainly affected the product selectivity; a higher pressure led to a lower C₁–C₄ selectivity but enhanced durene formation. Further increasing pressure also favoured coke formation, leading to faster loss of catalyst activity. Likewise, increasing WHSV reduced C₁–C₄ selectivity but promoted the formation of durene and coke, resulting in a rapid deactivation of the catalyst. The optimal reaction conditions for this nanocrystal ZSM-5 catalyst in MTG were found to be 375 °C, 1.0 MPa and WHSV of 2 h⁻¹.

使用XRD，ICP-AES，SEM，TEM，固态MAS NMR和氮物理吸附技术，合成了纳米纳米ZSM-5沸石，该沸石包含大小约为100 nm的均匀单晶颗粒。在甲醇转化为汽油（MTG）的过程中测试了催化性能，并特别关注反应条件的影响，即温度300至450°C，压力0.1至2.0 MPa和WHSV 1至4 h ^-1。温度显示出显着影响。在≤350°C的温度下，甲醇转化未完成，而催化剂失活得更快。将温度升高至375°C以上，可以看到甲醇完全转化，并且催化剂活性持久。将反应温度进一步升高至高于400℃会降低汽油收率。压力主要影响产物的选择性；较高的压力导致较低的C ₁ -C ₄选择性，但增强了杜伦烯的形成。进一步增加的压力也有利于焦炭的形成，导致催化剂活性的更快损失。同样，增加WHSV会降低C ₁ –C ₄选择性但促进了杜伦和焦炭的形成，导致催化剂快速失活。发现该纳米晶ZSM-5催化剂在MTG中的最佳反应条件为375℃，1.0MPa和2h ^-1的WHSV 。
