Tar catalytic reforming is the key to the utilization of biomass resources,and under the long-term reforming,the catalyst will lose its activity due to various reasons.Four types of catalytic systems of natural ores,biochar,nickel-based and composite catalysts are analyzed,and a catalyst performance and efficiency enhancement strategy is proposed on the basis of the catalytic inactivation mechanism.Studies have shown that nickel groups are essential elements for catalysts to play an effective role;catalyst carbon deposition,sintering and poisoning inactivation are closely related to the reaction temperature,and are also affected by factors such as catalyst loading,interaction ability between active components and poison cov-erage.By introducing metal-based supports and additives,and optimizing the catalyst into a core-shell structure,it is an important efficiency strategy to reduce the inactivation rate of the catalyst and improve the tar conversion rate.In future research,neural networks,density functional theory and other technolo-gies can be used to clarify the reaction path of tar reforming and optimize the preparation method of cata-lysts,so as to provide theoretical basis and practical value for improving catalytic performance.
