ADSORBENT AND FILTER FOR ELIMINATING SILOXANE GAS

摘要

PROBLEM TO BE SOLVED: To provide an adsorbent or a filter capable of eliminating adsorption siloxane gas with a high adsorption efficiency.

SOLUTION: The above siloxane gas is eliminated by adsorption by bringing an adsorbent comprising activated carbon fiber into contact with a gas to be treated containing the siloxane gas. The activated carbon fiber may have a BET specific surface area of 1,000-3,000 m2/g, and a pore of a porous radius of 0.2-1.8 nm by an MP method and an integrated porous volume of 0.4-2 cm3/g. The total volume of the pore with a porous radius of 0.3-0.6 nm by an MP method may be approximately 10-80 vol% of the integrated porous volume. The adsorbent may be composed of activated carbon non-woven fiber.
