Meanwhile, carbon dioxide is a major greenhouse gas contributing to climate change. The reforming of methane and carbon dioxide has been considered as a promising way to produce syngas, which can be further converted into fuels and valuable chemicals. In this regard, the development and optimization of catalysts for methane-carbon dioxide reforming is crucial.Objectives:This study aims to investigate the performance of Ni-CaO-ZrO2 catalyst in methane-carbon dioxide reforming reaction. More specifically, the objectives are:1. Synthesize and characterize Ni-CaO-ZrO2 catalysts with varying compositions.2. Evaluate the catalytic activity, selectivity, and stability of Ni-CaO-ZrO2 catalysts in methane-carbon dioxide reforming reaction under various reaction conditions.3. Investigate the effect of catalyst composition, reaction temperature, H2O/CO2 ratio, and space velocity on the reaction performance.Methodology:1. Catalyst synthesis: Ni-CaO-ZrO2 catalysts will be synthesized using a co-precipitation method. The catalysts will then be calcined, and characterized by XRD, BET, TEM, and TPR techniques to determine their physical and chemical properties.2. Catalytic performance evaluation: Methane-carbon dioxide reforming reaction will be carried out in a fixed-bed reactor using the synthesized catalysts. The reaction 精品文档---下载后可任意编辑conditions will be varied to study the effect of different parameters. The products of the reaction will be analyzed by GC to determine their composition and selectivity.3. Mechanism investigation: The reaction mechanism will be studied by performing isotopic tracing experiments by introducing 13C labeled methane and CO2.Expected Results:This study will provide insights into the performance of Ni-CaO-ZrO2 catalyst in methane-carbon dioxide reforming reaction and its potential applications. It is expected that the catalyst with optimized composition can achieve high catalytic activity, selectivity, and stability under the studied reaction conditions. The reaction mechanism will be elucidated by the isotopic tracing experiments, which can guide the development of more efficient catalysts. Conclusion:The optimization and development of catalysts are crucial for the success of methane-carbon dioxide reforming as a clean energy source. This study will contribute to the understanding of the performance and mechanism of Ni-CaO-ZrO2 catalyst in the reaction. The obtained information can be used to design and optimize catalysts for practical applications.
