| dc.description.abstract | The increased consumption and abundance of fossil fuels has led to significant greenhouse gases (GHGs) emissions, mainly CO2, which has led to health problems and climate changes. Therefore, it is essential to reduce the emissions of carbon dioxide to the atmosphere which contributes to protect our plant and the public health. Several technologies have been used in this regard such as carbon capture and utilizing it. The GTL (Gas-to-liquid) technology uses reforming units such as DRM (Dry Reforming of Methane) that utilizes COv2 to produce syngas for generating various products. Therefore, to mitigate carbon dioxide the reforming unit requires a catalyst to perform in the production of syngas by using two of the main GHGs, methane and carbon dioxide. This work is based on the synthesis of synthesizing Ni-based catalysts for DRM to produce syngas and specifically focuses on the preparation and characterization of hydrotalcite derived Mg-Al and doped Zn on Mg-Al with molar ratio of 2:1 for Mg: Al. The bimetallic supports were prepared via the co-precipitation method while metallic supports by precipitation method. The Ni-based catalysts were synthesized through the impregnation method. Furthermore, to avoid carbon deposition and sintering of the catalyst, the conducted temperature for DRM reaction was at 650 degrees C. The characterization technologies of the catalysts were performed using XRD, BET, FTIR, H2- TPR, and DRM reaction techniques to confirm the hydrotalcite structure and the metal-support interactions. | en |
