Document Type and Number:
WIPO Patent Application WO/2013/122027
Kind Code:
A1
Abstract:
A plurality of catalyst units (12) are positioned inside a container body (11), said catalyst units (12) comprising catalyst elements (22), and housing frame bodies (21) having trapezoidal cross sections, wherein a plurality of the catalyst elements are positioned. In a cross section of the container body: an imaginary circle (C) having a radius shorter than the radius of an inner circumferential circle (Co) of the container body, and a plurality of imaginary radiuses (r), which are positioned at equal angles and between the inner circumferential circle and the imaginary circle, are visualized, and an imaginary hexagon (K) inscribed in the imaginary circle is visualized; two first imaginary trapezoidal sections (P1) divided by an imaginary radius (R) that passes through the center of the imaginary hexagon, are visualized, and second imaginary trapezoidal sections (P2) are visualized inside imaginary band-like fan-shaped sections (B) partitioned by the inner circumferential circle, the imaginary circle and the imaginary radiuses of the container body; and the housing frame bodies of the abovementioned catalyst elements are formed in such a manner that the cross sections thereof coincide with the shape of the imaginary trapezoidal sections.
