摘要： A ceramic packing element (1) has a polygonal structure (2) with a plane of symmetry in a direction defining a length (L) of the element and a greatest dimension (D) perpendicular to the length defining a diameter of the element. The element has a plurality of internal septa (3) defining a plurality of identical first passages (4) through the element each of which has a first cross-sectional area and at plurality of second passages (5) of a larger cross-sectional area and at plurality of second passages (5) of a larger cross section area than that of one of the first passages. At least one of the second passages has a cross sectional area which is at least four times that of one of the first passages.
