Synthesis, characterization, and adsorptive desulfurization efficiency of ZIF-67 nanoadsorber Available to Purchase

In this work, the zeolitic imidazolate framework (ZIF-67) has been synthesized as an efficient adsorber for dibenzothiophene (DBT) removal from liquid model fuel via the adsorptive desulfurization method. Different characterizations were applied to assess the properties of the synthesized ZIF-67 adsorber. The effects of experimental parameters, DBT concentration in model fuel, and contact time have been investigated on the absorption performance of ZIF-67. The synthesized ZIF-67 presented a high surface area (1159.9 m2.g-1). Also, the ZIF-67 exhibited good DBT absorption uptake (86.12 mg.g-1). Moreover, the kinetics and equilibrium isotherm of DBT removal was considered. The pseudo-second-order kinetic model and the Freundlich isotherm exhibited well agreement with the experimental data.
