Removal of organic sulfur compounds by using an adsorption process was carried out at ambient temperature and pressure. FAU zeolites, including NaY, HUSY cation-exchanged with metal ions such as Cu, Ni, Zn, La, have been applied adsorbents in the desulfurization model real transportation fuels. The results showed that type ion-exchanged, amount structure zeolite important roles removal each sulfur. LaNaY, LaHUSY, CuNaY possessed highest capacity toward thiophene (TH), benzothiophene (BT),...
Abstract This study is the first report on preparation of mesoporous carbon/silica (MCS) nanocomposites with tunable mesoporosity and hydrophobicity using natural rubber (NR) as a renewable cheap carbon source. A series based NR hexagonal silica (HMS) were prepared via an in situ sol–gel process used precursors; then, they converted into MCS materials by controlled carbonization. The NR/HMS precursors exhibited high dispersion phase incorporated mesostructured framework confirmed small-angle...
(–)-Epigallocatechin gallate (EGCG) is a bioactive component of green tea that provides many health benefits. However, excessive intake may cause adverse effects caffeine (CAF) since (30–50 mg) has half the CAF content coffee (80–100 mg). In this work, for enhancing benefits tea, natural rubber/hexagonal mesoporous silica (NR/HMS) nanocomposites with tunable textural properties were synthesized using different amine template sizes and applied as selective adsorbents to separate EGCG from...
This study is the first report on synthesis, characterization and application of amine-functionalized mesoporous nanocomposites based natural rubber (NR) wormhole-like mesostructured silica (WMS). In comparison with WMS (WMS-NH2), a series NR/WMS-NH2 composites were synthesized via an in situ sol-gel method which organo-amine group was grafted onto nanocomposite surface co-condensation 3-aminopropyltrimethoxysilane (APS) as amine-functional precursor. The materials had high specific area...
Caffeine (CAF) removal from water resources is important because it widely distributed and can be toxic to aquatic life. The copper supported on mesoporous carbon/silica composite (Cu/MCS) in this research was developed as a novel adsorbent remove caffeine aqueous solutions. Cu/MCS material prepared two steps. first step the preparation of precursor consisting natural rubber inside hexagonal silica matrix (Cu/NR/HMS). Then, carbonized at high temperature under inert gas conditions obtain...
The use of rice husk ash functionalized with organic amine groups (RHA-NH2) as an adsorbent for acid dye adsorption from wastewater was studied. RHA–NH2 synthesized successfully via the grafting method using (3-Aminopropyl)-triethoxysilane (APTES) group precursors. adsorbents were characterized by X-ray Powder Diffraction (XRD), Fourier Transform Infrared Spectroscopy (FTIR), N2 adsorption-desorption analysis, and Scanning Electron Microscopy (SEM). RHA-NH2 exhibited amorphous silica...
