The conventional method for separating C₂H₄, cryogenic distillation, is highly energy-intensive. It operates under high pressure and extremely low temperatures to separate light olefins (e.g., C2H4 and propylene, C3H6) from their paraffin counterparts (e.g., C2H6 and propane, C3H8). This makes it one of the most energy-demanding steps in olefin production . Consequently, developing more energy-and cost-efficient alternatives for "alkenes from alkanes" separation has been recognized as one of the top seven transformative challenges in the chemical industry .
