Title: MONOLITHIC POROUS BODY COLUMN
Abstract:
A monolithic porous body column is configured from a monolithic porous body rod (2) having a cylindrical external shape and a framework with a three-dimensional network structure and from a metal pipe (3) for covering the monolithic porous body rod (2). In at least a portion of a plurality of sections partitioned along the axial direction, the initial diameter of the uncovered monolithic porous body rod (2) is larger than the internal diameter of the metal pipe (3) at the corresponding section, the compression of the covered framework within the range of elastic deformation causes the covered monolithic porous body rod (2) to have a covered diameter that is smaller than the initial diameter, the framework on the peripheral surface of the monolithic porous body rod (2) is dispersed throughout the entire periphery and touches the inner wall surface of the metal pipe (3), the diameter compression amount obtained by subtracting the covered diameter from the initial diameter is at least 0.01 mm, and the variation in the initial diameter in the circumferential direction of the monolithic porous body rod (2) is less than or equal to the diameter compression amount. The framework is resistant to heat at or above the heating temperature necessary for causing the internal diameter of the metal pipe (3) to increase through thermal expansion by more than the diameter compression amount.
