This technology overcomes challenges such as excessive byproducts, catalyst deactivation, and product regulation in ethane-CO2 coupling conversion. It develops efficient catalysts: under typical conditions, achieving 82–86% total ivity for C2H4/H2 trienes with excellent stability; developing flexible regulation of ethylene/CO/H2 ratios; and innovating lowenergy, short-process separation to meet downstream needs. A kiloton/year industrial trial has been completed, providing support for efficient low-carbon hydrocarbon utilization and CO2resourceization.
