Abstract
An adsorbent includes three or more columnar portions. The three or more columnar portions are joined to each other at their lateral sides with their axial directions extending parallel to each other such that a hollow space having opposite axial open ends and a closed lateral side closed by the lateral sides of the three or more columnar portions is defined between the three or more columnar portions.
Claims9
An adsorbent, comprising:
- three or more columnar portions and each having a lateral side and an axial direction;
- wherein the three or more columnar portions are joined to each other at the lateral sides with the axial directions extending parallel to each other such that a hollow space having opposite axial open ends and a closed lateral side closed by the lateral sides of the three or more columnar portions is defined between the three or more columnar portions.
A method of manufacturing an adsorbent comprising:
- preparing a viscous material by mixing activated carbon powder, a binder and water;
- extruding the viscous material by an extruder comprising a mandrel and a die with an opening, so that a molded body including three or more columnar portions and a hollow space is molded, wherein:
- the three or more columnar portions are formed by the opening of the die, and the hollow space is formed by the mandrel;
- each of the three or more columnar portions has a lateral side and an axial direction;
- the three or more columnar portions are joined to each other at the lateral sides with the axial directions extending parallel to each other;
- and
- the hollow space is defined between the three or more columnar portions and has opposite axial open ends and a closed lateral side closed by the lateral sides of the three or more columnar portions;
- and
- firing the molded body to form the adsorbent.
