充填物の開発が熱望されている。However, when the gas-liquid contact surface of the tubular structure is smoothly mirror-finished, the absorbing liquid flowing down the gas-liquid contact surface has a surface tension or a condensing force. As a result, it flows in the form of filaments, does not spread over the entire surface of the filling material, and has a reduced wetted area. As a result, the gas-liquid contact area efficiency may decrease and the gas-liquid contacting gas absorption efficiency may decrease. In addition, since many packings are used in the equipment, the gas-liquid contact efficiency is improved and it is easy to manufacture, and in order to process a large amount of gas efficiently, there is little resistance to the gas flow. Is desired. Under these circumstances, there is an eager need to develop a packing material that can further improve the transfer of components in a gas to a liquid and efficiently process a large amount of gas.

とができる。The filling material of the present invention is characterized in that it has through holes formed perpendicularly to the vertical gas passages. The pore size is preferably 0.1 to 2 mm, particularly preferably 0.3 to 1 mm.
