(326q) Separation of 1-Butene/n-Butane Using Mesoporous Mcm-41 Containing Cuprous/ferrous Ions Pair

1-butene, which is considerably important monomer in industry, has been usually produced by highly energy consuming separation based on distillation of C4 fractions in petrochemical plant. In this regards, there have been a lot of attempts to develop efficient separation methods of olefin and paraffin. In the present work, the adsorption characteristics of mesoporous MCM-41 containing cuprous, ferrous ions utilizing the g-complexation between the ions and 1-butene for selective adsorption of 1-butene in the mixture of the 1-butene and n-butane were studied. MCM-41 with cuprous/ferrous ions pair exhibit much higher adsorption amount for 1-butene than n-butane, compared to those of MCM-41 with only cuprous ion and microporous 13X zeolite. Especially, the MCM-41 with equal molar ratio of cuprous and ferrous exhibited the highest 1-butene/n-butane adsorption ratio at low pressure.
