This study investigated carbon monoxide methanation with 15 %NiO doped SAPO-34 zeolite-supported catalysts. The support was produced by hydrothermal synthesis, and nickel oxide added to the impregnation surfactant-assisted method, dissolved in different solvents (water, ethanol, acetone, 1-propanol). Various characterization techniques, N2 physisorption, XRD, SEM, TEM, FTIR, were used determine...

Hydrogenation of glucose into sorbitol has been a concern researchers for long time because it is an efficient and economical way producing sorbitol. The look alternative metals that are higher in abundance have good hydrogenation activity, such as nickel. In this study, porous nickel was prepared used catalyst the to without adding hydrogen gas. needs two stages making. First, prepare Ni/Al me...

Production of renewable and modified starch-based products was achieved using a sustainable catalyst an environmentally friendly drying process via supercritical CO2. Potato starch green esterification with acetic anhydride reagent implementing novel organocatalytic pathway at different periods time (0.5, 3 7 h) by applying reaction 120°C targeting intermediate degrees substitution (i.e., 0.2 <...

Carbon dioxide (CO2) assisted oxidative dehydrogenation of propane over Ga-modified catalysts is highly sensitive to the identity support, but underlying cause support effects has not been well established. In this article, SSZ-13, SSZ-39, ZSM-5, silica and γ-Al2O3 were used load Ga species by incipient wet impregnation. The structure, textural properties, acidity Ga-based process CO2-assisted ...

The synthesis of LiNbO(3) nanoparticles in SBA-15 is reported for the first time. The preparation of nanoparticles was carried out by impregnation from the metal precursor and mesoporous silica SBA-15 as the template. A rapid one-step treatment in an IR furnace reduces the preparation time to only 10 min. In comparison, a conventional furnace requires 5 h reaction time to produce nanoparticles ...

Ammonia has been suggested as a carbon-free hydrogen source, but a convenient method for producing hydrogen from ammonia with rapid initiation has not been developed. Ideally, this method would require no external energy input. We demonstrate hydrogen production by exposing ammonia and O2 at room temperature to an acidic RuO2/γ-Al2O3 catalyst. Because adsorption of ammonia onto the catalyst is ...

In the present study the use of cheap and ecofriendly biosorbents have been studied as an alternative substitution for commercial activated carbon for the removal of methylene blue from waste water. Batch adsorption study was carried out using inflorescence of Celosia argentea L, stem of Cicer arietinum and cob of Zea mays L as a raw agro waste material. This study investigates the potential us...

Nanoparticles of tin oxide, doped with Ce and Y, were prepared using the polymeric precursor method. The structural variations of the tin oxide nanoparticles were characterized by means of nitrogen physisorption, carbon dioxide chemisorption, X-ray diffraction, and X-ray photoelectron spectroscopy. The synthesized samples, undoped and doped with the rare earths, were used to promote the ethanol...
