摘要：
Increasing usage of lithium-ion batteries requires new recycling strategies. Dimethyl carbonate (DMC) and ethyl methyl carbonate (EMC) represent about 50% of the electrolyte and need to be captured from recycling exhaust gas. This study identifies adsorption as an advantageous method. Single component isotherms of DMC and EMC are presented applying the model of Toth. Model parameters are used to calculate binary adsorption isotherms with the ideal adsorbed solution theory. Comparison with experimental data shows good agreement in respect to selectivity, temperature dependence and overall gas loading.
