Fischer–Tropsch Synthesis for Light Olefins from Syngas: A Review of Catalyst Development

Light olefins as one the most important building blocks in chemical industry can be produced via Fischer–Tropsch synthesis (FTS) from syngas. FT conducted at high temperature would lead to light paraffins, carbon dioxide, methane, and C5+ longer chain hydrocarbons. The present work focuses on providing a critical review olefin production using synthesis. effects of metals, promoters supports influential parameters catalytic performance catalysts are discussed meticulously. Fe Co main active metals investigated terms pore size, crystal phase for obtaining desirable selectivity. Larger size Fe-based is suggested increase selectivity suppressing 1-olefin readsorption secondary reactions. Iron carbide probable proposed generation FTS. Smaller metal leads higher Hexagonal close-packed (HCP) structure has FTS activity than face-centered cubic (FCC) structure. Transition Co3C mainly formation over Co-based catalysts. Moreover, various catalysts’ deactivation routes reviewed. Additionally, techno-economic assessment plants different costs including capital expenditure minimum fuel selling price presented based recent literature. Finally, potential global environmental impacts associated with atmospheric toxicological considered lifecycle (LCA).
