The studies were performed with MOFs: MIL-125-Amine, MIL-53(Fe)-Cl, MIL-53(Fe)-Br and Fe-TazBz(DMF). It was observed that higher loadings were obtained for high pressure and low temperature. With MOFs like MIL-53(Fe)-Cl and MIL-53(Fe)-Br the components weren’t separated. In MIL-125-Amine hexane isomers were separated according to their boiling point, but the selectivity was small. The best result was obtained with MOF Fe-TazBz(DMF), because of the higher affinity of n-hex with this MOF, the separation from the other isomers was easier.Neste trabalho, mostra-se a capacidade de separação de isómeros do hexano com MOFs para aumentar o índice de octano da gasolina. O estudos fizeram-se nos MOFs: MIL-125-Amine, MIL-53(Fe)-Cl, MIL-53(Fe)-Br and Fe-TazBz(DMF). Observou-se que as maiores capacidades obtêm-se para a temperatura baixa e pressão alta. Nos MOFs MIL-53(Fe)-Cl e MIL-53(Fe)-Br os componentes não foram separados. No MOF MIL-125-Amine os isómeros foram separados seguindo aponto normal de ebulição dos compostos mas a selectividade é baixa. O melhor resultado obteve-se para o MOF Fe-TazBz(DMF) devido à maior afinidade deste composto com o MOF separando-o dos outros isómeros.engmaster thesis201456141
