摘要
传质性能是影响多孔催化材料,尤其是重质油催化转化催化材料催化性能的关键因素,因此,客体分子在工业催化剂颗粒内的传质行为成为当前一项备受关注的科学问题。近年来,本课题组的研究方向主要关注于客体分子在具有多级孔结构的催化剂颗粒内的复杂传质规律的辨析,并提出了一种运用空间分辨的方法进行多孔材料传质性能研究的全新理念,能够实现成型催化剂颗粒内客体分子传质过程的可视化。本研究以一系列粉末状分子筛样品和成型工业催化剂为研究对象,在系统表征催化剂的织构性质和酸性能的基础上,结合频率响应法(FR)和智能重量分析仪(IGA)两种传统方法,同时将荧光显微成像技术成功应用于多孔材料传质性能的研究,实现探针分子在催化剂样品中的传质行为的时间与空间分辨测量与辨析。
Mass transfer performance is a key factor influencing the catalytic properties of the porous petroleum processing catalysts,especially for the heavy oil catalytic conversion catalysts.Transport behaviors of guest molecules in the commercial catalysts,therefore,become a widely concerned scientific problem.The distinguishment of the complex transport behaviors of guest molecules in the hierarchical porous catalyst particles has been focused in our group,and a novel philosophy for the study of mass transfer performance by a space-resolved method,which is able to spatially map dynamic phenomena in the commercial catalysts has been proposed.A series of powdered zeolites and technical preformed catalysts were utilized as the research objects.Based on systematical characterization of the catalyst texture and acidic properties,mass transfer behaviors of probe molecules in the samples have been measured and discriminated by the Frequency Response(FR) method and an Intelligent Gravimetric Analyser(IGA).The fluorescence microscopic imaging technology as a space-resolved method is firstly explored to study the mass transfer performance.
