A method for disposal of ozone-depleting CCI4 by disproportionation reaction with CH4 to produce CH3Cl and CHCl3 has been investigated over various platinum-based catalysts. The catalysts were supported mainly on SiO2 and MgO and also modified by the addition of manganese to improve the catalyst lifetime. Platinumbased catalysts supported on SiO2, ...

MoNi/gamma-Al2O3 catalysts were prepared by the impregnation method. The catalyst samples were characterized by XRD and TPR. The effects of Mo promoter content and the catalyst reducing temperature Oil hydrotreatment activity of the catalyst were studied under 200 degrees C and 3 MPa hydrogen pressure using acetic acid as the model compound. The XR...
We report the preparation and characterization of Ni nanoparticles supported on barium hexaaluminate (BHA) as CO methanation catalysts for the production of synthetic natural gas (SNG). BHA with a high thermal stability was synthesized by a coprecipitation method using aluminum nitrate, barium nitrate, and ammonium carbonate as the precursors. The ...
Nickel catalysts supported on the perovskite oxide CaTiO3 (CTO) were prepared by an impregnation method for CO methanation to produce synthetic natural gas (SNG). X-Ray diffraction, nitrogen adsorption, scanning electron microscopy, transmission electron microscopy, thermogravimetric analysis, H-2-temperature programmed reduction and desorption, an...
Autothermal carbon dioxide reforming of methane was studied over trimetallic NiCoMn/ZrO2 catalyst promoted with different promoters (Ce, La, Ca, K) aiming to improve the performance of the catalyst and increase their resistance to coking. The promoted catalysts prepared by a coprecitation method showed metal sizes less than 10 nm and were studied w...
