摘要
文章对与粉煤灰合成沸石制备方法相关的专利申请时间分布、申请人状况以及主要制备方法进行了分析和探讨。研究表明,高校和科研单位为该领域主要研究群体,水热法、碱熔法等制备方法为我国目前专利申请中制备粉煤灰合成沸石的主要方法选择,同源粉煤灰制备方法研究以及非水热制备方法可能成为今后粉煤灰合成沸石行业的主要发展方向。
In the paper, the distribution of application date, applicant, and preparation methods related to synthesized zeolite from fly ash are briefly analyzed and discussed. The patent analysis reveals that, colleges and research institutions appear to have a competitive advantage in this field at present. It also indicates that hydrothermal and alkali fusions are the main method choices among patent applications. The research of fly ash of common source and non-hydrothermal methods may become the main development directions of the industry of synthesized zeolite form fly ash.
