摘要
90％以上石油化工生产过程涉及催化材料,催化材料的传质能力直接关系其催化性能,因此,作为体现催化材料传质能力的重要指标之一,比表面积和孔结构是石油化工催化材料研发、生产和质量控制中重点监测的物性参数.气体物理吸附法是当前表征石油化工催化材料比表面积和孔结构的主要技术手段.主要介绍了气体物理吸附法测定技术及主要技术进展,结合近年来石油化工催化材料在孔道调变、梯级孔构建、载体性能研究与催化剂积炭失活解析的部分实例阐述气体物理吸附法在石油化工催化材料表征中的应用.在此基础上,对物理吸附法的未来发展方向进行了展望.
Abstract
The mass transfer capacity of catalytic materials,which are involved in more than 90％of petrochemical processing,is directly related to their catalytic performance.Therefore,the specific surface area and pore structure,as the important indexes characterizing mass transfer capacity,are key physical parameters that should be closely monitored in research,production and quality control of catalytic materials.Currently,gas physical adsorption is the main technique for characterizing the specific surface area and pore structure of petrochemical catalytic materials.This paper mainly introduces the gas physical adsorption method and its major progress.Moreover,some practical examples regarding pore modulation,hierarchical-pore construction,research of carrier performance and analysis of catalyst deactivation are cited to illustrate the application of gas physical adsorption method in the characterization of petrochemical catalytic materials.On this basis,the future development trend of the method is prospected
