Progress in patent technologies for methane catalytic combustion catalysts research

Catalytic combustion is an important approach to the effective utilization of methane, with the key being the search for efficient catalysts to maximize catalytic activity and resistance to poisoning. This work is based on the IncoPat commercial global patent database, combined with search results from the China Patent Abstracts database and the Derwent World Patents Index database, employing patent analysis methods to conduct a comprehensive analysis of the development trends in the global methane catalytic combustion catalyst materials technology field. By analyzing the trends in patent application and patent family numbers, the distribution of applicant countries/organizations, and leading applicants, this study summarizes the classification, preparation methods, and other technical key points of methane catalytic combustion catalyst materials, clarifying the latest developments in global methane catalytic combustion catalyst materials technology. This provides technical references for companies producing methane combustion catalytic materials in terms of product development and patent strategy layout, and supports the rapid development of the global methane combustion catalytic materials industry. The research findings indicate that global methane catalytic combustion catalyst technology is in a phase of rapid development, with research and applications in this field accelerating globally among countries and organizations, displaying intense technological competition and cooperation trends. Future research will focus on enhancing the activity, stability, and resistance to poisoning of catalysts, to aid in methane reduction and provide technical support for achieving global climate goals.
