“…3,4 This modification allowed a threefold reduction of the standard error of fitting experimental adsorption data of the H 2 /AX-21 TM system over a wide temperature and pressure range in the supercritical region. It also made it possible to fit the model's parameters using only two isotherms measured at 77 K and 298 K without significantly reducing the quality of the fit over the whole ).…”

Preliminary evaluation of the performance of an adsorption‐based hydrogen storage system

et al. 2009

View full text Add to dashboard Cite

in Wiley InterScience (www.interscience.wiley.com).Using modeling and thermal simulations, the feasibility of an adsorption-based hydrogen storage system for vehicles is evaluated. The storage capacity of a 150 L tank filled with a high surface-area activated carbon is mapped for temperatures from 60 to 298 K and pressures up to 35 MPa. The thermal simulations are verified using experiments. For a storage capacity target of 5 kg, the adsorption-based storage system will offer a storage advantage over the cryogenic gas storage if the residual mass of hydrogen in the tank is retrieved by heating. For a discharge rate of 1.8 g/s, the required heat is of the order of 500 W. The net energy requirements for the refueling has contributions from compression, precooling and tank cooling and can approach that for liquid hydrogen storage. With a good insulation and a maximum tank pressure of 35 MPa, the dormancy period can be extended to several weeks. V

“…But in this study only one overall energy balance was utilised by combining the two energy balances in the gas and stationary phases under an assumption that the adsorbent, adsorbed gas and gas phases are at their thermal equilibrium in the control volume (Mahle et al 1996;Richard et al 2009).…”

New momentum and energy balance equations considering kinetic energy effect for mathematical modelling of a fixed bed adsorption column

et al. 2015

View full text Add to dashboard Cite

It was aimed to derive rigorous momentum and energy balance equations where the change of kinetic energy in both spatial and temporal domains of a fixed-bed adsorption column was newly taken into account. While the effect of kinetic energy on adsorption column dynamics is negligible in most cases, it can become more and more influential with an adsorption column experiencing a huge pressure drop or with the gas velocity changing abruptly with time and along the column. The rigorous momentum and energy balance equations derived in this study have been validated with two limiting cases: (1) an inert gas flow through a packed column with a very high pressure drop and (2) blowdown of an adiabatic empty column. The new energy balance including the kinetic energy effect paves a way for simulating with an improved accuracy a Rapid Pressure Swing Adsorption process that inherently involves a very high pressure drop along the column and requires very high pressure change rates for column blowdown and pressurisation.

“…The heat of adsorption cannot be neglected. Its value depends on temperature and surface loading, for interesting pressure range of can be estimated according to [4] as a range 12 -20 kJ/mol The isotherms showed in FIGURE 2 are a compilation of data published in [5] and the experiments performed in National University of Singapore. The observed temperature dependent shape is an indication of possible pressure benefit for different filling temperatures.…”

The article provides an introduction to innovative method of Liquid Natural Gas (LNG) physical exergy practical utilization. The energy spent to liquefy natural gas (a thermodynamic minimum is about 0.13 kWh/l of LNG depending on pressure and chemical composition) can be partly recovered in the system making use either of the LNG low temperature (111 K) or its ability to increase the pressure in a storage vessel by heat absorption from the environment. The paper presents estimation of the LNG physical exergy and its dependence on the pressure and temperature. Then description and comparison of available natural gas storage methods (liquefaction, compression, adsorption) is given, with a special attention paid to Adsorbed Natural Gas (ANG) technology. Original data concerning adsorption isotherms of methane with activated carbon MaxsorbIII are presented. A concept of ANG storage technology coupled with the LNG regasification, is a promising technique of utilization of the LNG cold exergy. The energy efficient combination of ANG with LNG may help market progress of adsorption technology in natural gas storage and distribution. The ANG/LNG coupling is especially perspective in case of small capacity and distributed natural gas deposits exploitation.
