A systematic investigation into the performance of nanocrystal and hierarchical ZSM-5 Zeolites in MTG

    Research output: ThesisDoctoral Thesis

    Abstract

    This thesis details a systematic investigation into the performance of nanocrystal and hierarchical ZSM-5 zeolites in methanol to gasoline conversion. Both zeolites showed much improved performance over conventional ZSM-5 zeolites in terms of methanol conversion, gasoline yield and catalytic lifespan. The effect of catalyst crystal size and Si02/AI203 ratio and reaction conditions on the performance of nanocrystal catalyst was studied in detail. The mechanisms of the formation and characteristics of coke deposits relating to catalyst deactivation was understood and the scientific principle underpinning the superior performance of the nanocrystal catalyst outperforming the microcrystal counterpart was established.
