To synthesize a bifunctional catalyst on an Al₂O₃ support, the initially used adsorbent Al2O3 was regenerated at 600 °C for 360 minutes in the absence of atmospheric oxygen. A process model for synthesizing bifunctional catalysts on regenerated Al₂O₃ support was developed using Ni, Co, Mo, and P precursors. According to the elemental composition analysis of the regenerated adsorbent by XRF (X-ray fluorescence) method, it was determined to consist of 81.5 % Al2O3. Using the regenerated Al2O3 as the support, (NH4)6Mo7O24·4H2O, Ni A process model was developed to synthesize a bifunctional catalyst using salts such as Ni(NO3)2·6H2O, Co(NO3)2·6H2O, and H3PO4 acid, and based on this model, three types of catalyst samples were synthesized. To determine the morphological changes and textural properties of the surface of the obtained catalyst samples, analyses were performed using SEM (Scanning Electron Microscope), TEM (Transmission Electron Microscope), and BET (Brunauer-Emmett-Teller) model-based methods. These analyses were applied to evaluate morphological changes and textural characteristics of the prepared catalyst samples.
