OX-Zeo Bifunctional Catalyst Concept Enables Syngas Conversion to Light Olefins and Beyond

摘要

Light olefins, include ethylene, propylene and butylene, are important chemical building blocks which are widely used for producing plastics, cosmetics, and drugs. Syngas, as a platform of coal, natural gas and biomass utilization, can be transformed to light olefins via traditional Fischer-Tropsch synthesis (FTS).1 However, hydrocarbon distributions of FTS follows the so-called Anderson-Schulz-Flory (ASF) distribution, according to which the selectivity of C2-C4 hydrocarbon does not exceed 58%.1-3 Therefore, to precisely control the C-C coupling as well as suppress the methane formation and over-hydrogenation of olefins are key challenges in this filed.
