In this article, a novel hybrid catalyst composed of CuO and ZSM-5 for the direct synthesis of gasoline hydrocarbons from CO2 and hydrogen is introduced and evaluated. The aim of this research is to improve the efficiency and stability of the catalyst in converting CO2 to value-added products and to reduce greenhouse gas emissions. Initially, the catalyst was prepared using the impregnation method, and its structural and chemical characteristics were examined using XRD, BET, and TPD-NH3 tests. The results indicate that the CuO/ZSM-5 catalyst is capable of producing gasoline hydrocarbons with high selectivity. Additionally, the effects of operational parameters such as reaction temperature and H2/CO2 ratio were investigated. The optimal operational conditions over a reaction time of 10 hours were determined to be a temperature of 320°C and an H2/CO2 ratio of 3:1. Under these optimal conditions, the CO2 conversion rate reached 36.2% and the selectivity for C5+ hydrocarbons reached 61.7%. Moreover, stability tests demonstrated that this catalyst could maintain its activity and selectivity over a prolonged period.
