Adsorption

A new approach model was developed for the pore size characterization of carbon porous materials, using adsorption gases. The experimental adsorption isotherms of CO2 and N2 onto carbon nanoparticles were used to test the validity of such model.

The recycling of precious metal ions is highly desirable to the environment and economy. In this work, zeolitic imidazolate framework-8 (ZIF-8), a porous and relatively stable adsorption material, was explored for the adsorption of Au from water.

Adsorption isotherms and zero length column (ZLC) desorption curves of alkylbenzene (toluene and isopropylbenzene) in a series of microspherical ZSM-5 zeolites with inter- and intracrystalline mesopores were measured for revealing structural and …

Activated carbon fibers (ACFs) with surface modified by a diethylene triamine (DETA) are synthesized for the abatement of formaldehyde in gas phase at low concentration. Adsorbents with several DETA loadings were tested and characterized. The …

The separation of xylene isomers feedstock containing ethylbenzene is still a relevant industrial challenge. The increase in p-xylene consumption worldwide promotes the search for more efficient separation processes. One possible way to achieve …
