  • Publication number: 20200164343
    Abstract: Adsorbent polymeric structures are described. These adsorbent polymeric structures are capable of separating non-polar hydrocarbons, such as crude oil or diesel fuel, from polar liquids, such as water. The adsorbent polymeric structures may include acid grafted graphene and at least one styrene. A method of preparing an adsorbent polymeric structure may include mixing graphene and at least one acid catalyst in a polar liquid in the presence of at least one alcohol to form an acid grafted graphene via an esterification reaction; and the acid grafted graphene and at least one styrene monomer are introduced to water in the presence of an initiator to form the adsorbent polymeric structure according to any of the previously-described embodiments via an emulsion polymerization reaction. Moreover, the adsorbent polymeric structures may be incorporated into methods of fluidly separating at least one non-polar hydrocarbon from a polar liquid.

  • Patent number: 9926495
    Abstract: Alumina/NiO/ZnO and Alumina/ZnO are synthesized via a novel modified hydrothermal method and investigated for the desulfurization activities. Sulfur compounds such as thiophene, benzothiophene (BT) and dibenzothiophene (DBT) are tested for their removal from model diesel fuel. The prepared composite materials were examined by the means of N2-adsorption, X-ray diffraction and Fourier transform infrared spectroscopy.

  • Patent number: 9687813
    Abstract: Activated carbon (AC) composites as adsorbents for mercury removal in water treatment. The AC composites comprise an AC as the core particle, with aluminum oxide (Al2O3) and polyethylenimine (PEI) grafted on the surface of the AC core particle to increase the surface area, number of active sites and adsorption capacity. Methods of preparing and characterizing the AC composites by scanning electron microscope (SEM), energy dispersive X-ray (EDX) and Fourier transform infrared absorption spectroscopy (FTIR) are also provided.

  • Patent number: 9352297
    Abstract: Activated carbon\nickel oxide\zinc oxide (AC\NiO\ZnO) and activated carbon\zinc oxide (AC\ZnO) were prepared and used as adsorbents for removal of thiophene, benzothiophene (BT) and dibenzothiophene (DBT) as sulfur compounds from hydrocarbon materials such as diesel fuel. The materials exhibited an efficient and economical way for removing sulfur compounds due to its low-energy consumption, ambient operation temperature and atmospheric pressure.
