IR Spectral Investigation of the Multistage Single Catalytic Process of CH_4 conversion into Higher Hydrocarbons over HZSM-5 Structurally modified with An Oxidative element

摘要

The acidic zeolite HZSM-5 is modified by partial isomorphous substitution of the framework aluminum (Al) with an oxidative element during the zeolite synthesis. This is to develop an oxidative-acidic mediated catalyst suitable for the direct conversion of methane (or natural gas) into higher hydrocarbons in a multistage single catalytic process. The pure and modified ZSM-5 materials are highly crystalline of high morphology, which is shown by XRD and SEM.
