De-oxygenation of CO2 by using Hydrogen, Carbon and Methane over Alumina-Supported Catalysts [PDF]

open access: yes, 2012
The de-oxygenation of CO2 was explored by using hydrogen, methane, carbon etc., over alumina supported catalysts. The alumina-supported ruthenium, rhodium, platinum, molybdenum, vanadium and magnesium catalysts were first reduced in hydrogen atmosphere ...

CO2 Methanation Over Ni-Sepiolite Catalysts

open access: yesEuropean Journal of Science and Technology, 2021
In this study, it was aimed to develop new catalysts to increase the conversion of environmentally harmful carbon dioxide gas to methane which is a valuable fuel. By using a natural clay mineral sepiolite (SEP) as support material; 6-8% (weight-weight) Ni- containing catalysts were prepared by impregnation. Catalysts were characterized by XRD and FT-IR
