Description
Global warming is a main issue for every country that affects the increasing of Earth’s temperature, caused by greenhouse gas emissions into the atmosphere, especially methane (CH4) and carbon dioxide (CO2). Therefore, the utilization of CO2 and CH4 gases is an interesting approach. They can be used as reactant gases in the dry reforming reaction, with the resulting products further used as reactant gases in the Fischer–Tropsch process to produce high-value hydrocarbon products. This research developed a nickel catalyst, supported by cerium oxide-magnesium oxide modified porous silica (CeMgPS) for the dry reforming reaction. The CeMgPS support was synthesized by using co-precipitation method, and nickel metal was loaded via impregnation technique. The catalyst was tested in dry reforming at 700 °C under atmospheric pressure. As a result, the Ni/CeMgPS catalyst exhibited higher CH4 and CO2 conversions and a higher H2/CO ratio compared to other catalysts. This was due to the Ce-Mg modified PS-supported Ni catalyst having a higher surface area, as well as the strong interaction between the Ni and the CeMgPS support. This interaction aids in the well-dispersed distribution of active nickel on the support, resulting in increased activity and stability during the reaction.
