Abstract

The actual applications of extraction methods for α-olefins separation are limited by their long time and high energy consumption. Hence, this study employs microwave technology to intensify the extraction process using Ag-based ionic liquid (Ag-IL), where the influence of microwave irradiation and the mechanism of microwave-assisted ionic liquid extraction (MAILE) are investigated, along with a comprehensive techno-economic analysis of process feasibility. The results of COSMO-RS and DFT simulations demonstrate the dominant role of π-complexation in identifying Ag-IL with high selectivity, indicating the possible enhancement caused by microwave irradiation. The subsequent kinetic experiments show that compared with conventional routes, the MAILE accelerated the extraction process by approximately 89.72%. As a result, the total annual cost of unit product of the overall process is reduced by 6.43% according to techno-economic analysis by Aspen Plus, indicating that MAILE is a cost-effective, scalable, and sustainable approach to α-olefin separation, offering process efficiency and environmental sustainability.

微波辅助Ag-IL萃取分离α-烯烃：机理及工艺强化

萃取法分离α-烯烃的时间长、能耗高，限制了其实际应用。因此，本研究采用微波技术强化银基离子液体（Ag-IL）萃取过程，研究微波辐照对银基离子液体（Ag-IL）萃取的影响及微波辅助离子液体萃取（MAILE）的机理，并对工艺可行性进行综合技术经济分析。cosmos - rs和DFT模拟结果表明，π络合在高选择性识别Ag-IL中起主导作用，表明微波辐射可能对Ag-IL有增强作用。随后的动力学实验表明，与常规路线相比，MAILE的提取速度提高了约89.72%。结果，根据Aspen Plus的技术经济分析，整个过程的单位产品年总成本降低了6.43%，表明MAILE是一种具有成本效益，可扩展且可持续的α-烯烃分离方法，具有工艺效率和环境可持续性。
