主　　题：F-T synthesis Zeolite Ru nanoparticles Gasoline 

摘      要：Product selectivity control is attractive in Fischer-Tropsch(F-T)synthesis but it is still a challenge,because the F-T products follow the Anderson-Schulz-Flory(ASF)distribution with maximized gasoline-ranged(C_(5)-C_(11))hydrocarbon selectivity at 45%.Herein,we report a strategy by optimizing the gasoline selectivity to outperform the ASF *** key to this success is fixation of the metal nanoparticles within zeolite crystals(metal@zeolite),where the zeolite micropore adjusts the product *** example,the Ru@NaY exhibited the gasoline selectivity 64.3% in the F-T reaction,which is significantly higher than the ASF limitation and about 2 times of that(32.8%)over conventionally supported Ru catalyst(Ru/NaY).This investigation might offer an alternative route for the direct transformation of syngas to liquid fuels with controllable selectivities.
