摘要：

The role of Gd as a coke inhibitor was studied for the methanol-to-hydrocarbons reaction. It was revealed that thin films of gadolinium oxide covered the ZSM-5 crystals and that the Gd atoms that were uniformly dispersed on the surface enhanced the basicity of the parent ZSM-5. These synergetic effects improved the durability of the acidic function and diminished the growth of coke precursors, which resulted in an increased lifetime of the catalyst.
