    • Catalyst support elements are shaped to provide large surface area per unit of volume (porosity), while providing high packing density. Generally, the elements are characterized by more than six faces of identical size and shape, and by members extending outwardly in three dimensions. Each element includes a plurality of concave regions defined by the intersection of various of their planar surfaces, yet the element is not simply a section of an extrusion. An exemplary such element is the Reticulon (41), which has the shape of two diametrically opposed, truncated obelisks extending from two opposing faces of an octagonal base column. Five-sided pyramids of equal size and proportion extend from distal ends of the truncated obelisks, as well as from those alternating faces of the octagonal base column which coincide with the faces of the obelisks. Aggregates for reinforcing structural matrices can also be formed according to such geometries. Known fabrication methods and apparatuses, including patterned pinch rollers, molds, etc., are adapted to create such articles. In certain embodiments, vibrational energy (e.g. ultrasonic or microwave energy) is utilized to aid in article formation.
    • 催化剂支撑元件被成形为提供单位体积​​(孔隙率)的大的表面积,同时提供高的堆积密度。 通常,元件的特征在于具有相同尺寸和形状的六个以上的面,以及通过在三维中向外延伸的构件。 每个元件包括由它们各自的平面表面相交而限定的多个凹形区域,但该元件不是简单的挤压部分。 示例性的这种元件是Reticulon(41),其具有从八边形基柱的两个相对面延伸的两个直径相对的截顶的方尖碑的形状。 相同尺寸和比例的五边形金字塔从截顶的方尖碑的远端以及与方尖角的表面重合的八角形基列的交替面延伸。 用于加强结构基体的骨料也可以根据这些几何形状形成。 已知的制造方法和装置,包括图案化夹送辊,模具等,适于产生这样的制品。 在某些实施例中,利用振动能量(例如超声波或微波能量)来帮助制品形成。
