くすることが実用上重要な問題てあつｆ（、。Absorption refrigerators use a highly corrosive concentrated lithium bromide aqueous solution and are operated at high temperatures, so corrosion of the constituent materials becomes a problem. For this reason, inhibitors are added to the absorption liquid to prevent corrosion, but it is practically impossible to completely prevent corrosion. Therefore, in a refrigeration system that operates under reduced pressure, when hydrogen caused by corrosion accumulates, the internal pressure increases and the performance deteriorates. Regarding b', metallic palladium is available as a hydrogen remover, but because it is a thin film, its ability to remove hydrogen is small and it is extremely expensive. - Therefore, the present inventors first proposed a method of using oxides for gold. This method provides very high hydrogen removal efficiency). However, gold M1

To completely fill / r\c"t,!, t, is a hexa-hydrogen removal agent. As a means of filling the oxidized steel, porous spherical alumina is immersed in an aqueous solution containing Lf same ions.
It may be impregnated with copper ions and oxidized at a high temperature, or copper may be plated directly on the surface of the porous spherical alumina and inside the pores using a reducing agent such as a chemical copper plating solution.
This may be used as 1-1.

When the reaction tube 3 is filled with the hydrogen removal Q agent 4 obtained in the present invention, the packing density is 70%, whereas the filling rate of conventional copper oxide pellets and wires is at most 53%. Since the packing density is increased, the contact rate with hydrogen is increased.The reaction tubes 3 ij are heated with the heater 5 as a whole [2, and the hydrogen removal 7i11 is heated to 30OU. Continuously supply hydrogen gas to this reaction tube 3 (Ml at 2).
