The invention belongs to the technical field of zeolite materials, and particularly relates to an axial heat-conducting zeolite honeycomb material as well as a preparation method and application thereof. The preparation method provided by the invention comprises the following steps: S1, filtering first pug through n stages of filters in the presence of a low-boiling-point organic solvent, forming a wedge-shaped filter hole in each stage of filter, and gradually reducing the aperture size of the wedge-shaped filter hole in the filtering direction, the aperture size of the wedge-shaped outlet of each stage of filter is smaller than the length of the fiber heat-conducting material, so that the fiber heat-conducting material is directionally distributed to obtain second pug; and S2, the second pug is subjected to aging treatment and then extrusion molding, and then shaping and sintering treatment are carried out. The key of the invention lies in that the axial heat-conducting property and desorption efficiency of the zeolite honeycomb material are improved through the synergistic effect of the low-boiling-point organic solvent and the n-stage filter with the wedge-shaped filter holes.
本发明属于沸石材料技术领域，具体涉及一种轴向导热的沸石蜂窝材料及其制备方法和应用。本发明提供的制备方法包括：S1.将第一泥料在低沸点有机溶剂存在的条件下通过n级过滤器过滤，每一级过滤器中设有楔形过滤孔，锲形过滤孔的孔径尺寸沿着过滤方向逐渐减小，且每一级过滤器的锲形的出口孔径尺寸小于纤维导热材料的长度，使得纤维导热材料定向分布，得到第二泥料；S2.将第二泥料陈腐处理后挤出成型，再进行定型、烧结处理。本发明的关键在于通过低沸点有机溶剂和具有锲形过滤孔的n级过滤器的协同作用来提高沸石蜂窝材料的轴向导热性能及脱附效率。
