Storage value

To conclude this section, widespread consensus exist that the adsorbents with the highest methane capacity are the carbonaceous materials, especially activated carbons [192], where storage values up to 200 v/v have been reported [213],... 

The hydrogen storage values of PIMs and HCPs are still smaller than for many porous carbon samples. However, PIMs and HCPs have only recently been investigated for H2 adsorption and further modifications of these materials can lead to an enhancement of their hydrogen storage capacity at cryogenic temperatures. 

Values skjtemp are abbreviated as sk. The figure shows the situation after three real messages have been signed. Only the encircled values have to be in private storage. Values crossed out have been deleted. The remaining values are in authentic storage, where authi is the information stored in authentic storage instead of ski, i.e., (mi, si, in Construction 10.19. 

Prior to this report, there had been two other studies that indicated relatively high hydrogen storage capacities on ahgned MWNTs [29, 30]. The storage values found in those reports were close to 3wt% at 10 MPa and room temperature. 

The set of low hydrogen storage capacity reports [14—16, 24, 25] are able to explain why some of the initial work reporting high storage values were in all likelihood incorrect [4, 5, 23]. The formation of hydrides, the effects of small leaks in volumetric adsorption setups, or those of uncorrected fluctuations in the temperature can explain the initial high storage values reported. 

The amount of NOx stored during each lean phase is presented vs. temperature in Fig. 2 for cycles with 240 s in the lean phase followed by 60 s in the rich phase. In the temperature interval studied, a maximum in NOx storage is found at around 380°C and very low values above 500°C are measured. Also shown is the corresponding storage values when using NO2 in the feed gas rather than NO. The latter shows similar appearance as with NO. 

Ye et al. carried out volumetric measurements on purified and DMF sonicated SWCNT at cryogenic temperatures. The authors obtained a high storage value of... 

Calcium ion concentration is an important property of apples. It seriously affects the post-harvest marketing and storage value of it. Usually, the measurement of the calcium concentration in fruits like apple is made by drying and burning the fruit and analyzing the ashes with atomic absorption spectroscopy. Knee and coworkers [65] observed that the considerable part of calcium ions in the apple is bound to cell walls. 

In the first case. Mode 1, the B OR increased relatively slowly with time to a peak value over a period of 60 min or more, and then subsided equally slowly back to the normal storage value. The excess evaporation tracked the rise and fall of liquid superheat in the upper layer, as the mixing proceeded spontaneously to completion and as the thermal overfill was released. The interface also moved down very slowly. All was very peaceful but uncontrollable, without any emergency venting to the atmosphere.
