example 1
[0038] Cylindrical scrubber vessels of 4 cc volume with a length of 4.8 cm and a diameter of 1.04 cm were filled with different purification materials and subjected to the activation process according to the protocol in Table 1 indicating the materials and the equilibrium temperature during the activation process. In Table 1, the parameters common to all samples, namely the type of gas flowing during activation (nitrogen), the flow rate (0.5 l / min) and the total length of the activation process (21 hours) have been omitted.
[0039] Table 1
[0040] Sample identification
[0041] Sample 1 was essentially supported by fully oxidized nickel (NiO) due to the exposure of the material to air prior to the activation process. Nickel used for sample S1 has 180m 2 / g surface area.
[0042] All preceding samples have been exposed to 0.1 l / min of N 2 O stream, which contains approximately 50 ppm CO 2 , and the outlet of the purifier was connected to a TraceAnalytical RGA5 g...
example 2
[0048] After the media in the container had exhausted its capacity (analyzer connected downstream reached a reading of 0.5 ppm), the sample S1 made according to the exemplary embodiment was subjected to a reactivation process, i.e. the activation process described in Table 1 was repeated . As a proof that the material is fully reproducible and compatible with the application, after reactivation, the properties of sample S1 were measured to obtain the same values.
