Abstract
This paper mainly studies the related theories and limiting factors of producing hydrogen from carbon dioxide, and puts forward some improvement measures for these limiting factors. The basic principle of producing hydrogen from carbon dioxide and the common process of producing hydrogen are described. Then, the influences of limiting factors such as pyrolysis temperature, reaction pressure, catalyst and reactant ratio on reaction efficiency and product quality were analyzed in detail. Then, this paper puts forward four improvement measures, such as optimizing catalyst selection, changing reaction conditions, changing reactant proportion and using high-tech means, and illustrates the advantages and disadvantages and feasibility of each measure. Finally, the improvement measures proposed in this paper are summarized, and the importance of carbon dioxide to produce hydrogen technology for clean energy is emphasized. The research results of this paper can provide theoretical guidance and technical support for scientists in related fields.
