Direct conversion of syngas to gasoline ranged olefins over Na impellent Fe@NaZSM-5 catalyst
2022
Abstract Directly synthesizing olefins from syngas using metal-zeolite composite catalysts has engrossed a lot of attention recently. Fe-based catalysts will be the most promising industrial candidates due to cost and availability constraints. In this work, we investigate the characteristics and Fischer-Tropsch activity of a novel Fe@Na-ZSM-5 composite for one-step conversion of syngas to higher olefins (C5+). The in-situ crystallization mechanism induced Na in the ZSM-5 as a Fe-based promoter which realized 52.5 % selectivity for gasoline of which ∼ 70% were olefins. Additionally, the promotion by the Na ions enhanced the formation of Fe5C2 phases which in turn favored C–C coupling, high gasoline and olefins selectivity. Na type zeolite (Na-Zeolite) offers a novel Na electron promoter, which participate immensely in the development of heterogenous catalyst and functional materials.
