Light olefins are crucial in the field of catalysis because they are key intermediates in many industrial processes. Catalysis enables the efficient production of these olefins through processes like steam cracking, fluid catalytic cracking (FCC), and methanol-to-olefins (MTO). The catalytic processes not only enhance the yield and selectivity of light olefins but also reduce energy consumption and minimize byproduct formation, making the overall process more sustainable.
