Adsorbed Phase

The performance of an adsorbed natural gas (ANG) storage system with natural convection heat transfer between the ANG bed and the ambient air is studied. Results are obtained for the bed without and with external fins on ambient air side. A one dimensional transient conduction model with suitable kinetic equation is formulated to simulate the performance of the bed filled with a homogeneous mixture of activated carbon and graphite. The model duly considers non-ideal behaviour of natural gas, variable specific heat of the adsorbed phase and heat of adsorption. Results are obtained for the case of constant pressure charging and constant flow discharging. The performance of the ANG bed is evaluated in terms of delivery capacity and discharge time. Results are obtained at an ambient temperature of 308 K and 35 bar for a charging time of 3.34 min. It is found that under this condition, the bed temperature increases by 70 and 45K and the storage capacity reduces by 75 and 60% without and with external fins, respectively. During discharge also, due to insufficient heat supply the bed temperature drops to very a low value thereby increasing the amount of adsorbate retained at the end of discharge process. This study clearly shows the need for improving the heat transfer rate from or to the ANG bed for higher delivery capacity.

Diffusion Behaviors

Natural gas (methane is the primary constituent) adsorbed on nanoporous materials is a promising alternative to compressed natural gas as a cleaning fuel. To understand the transport of methane confined in a nanoscale pore is useful for developing and optimizing some related industry processes. Equilibrium molecular simulation were carried out to study the transport behaviors of methane confined in two types silica pores, a cristobalite silica pore and an amorphous silica pore. Many factors, such as temperatures, densities of methane and surface structures of pore, which could affect the transport of methane, were examined in simulations. Simulations calculated the diffusion coefficients of methane at different densities and temperatures. The detailed microscopic structures of pores have a great correlation with the diffusion behaviors of methane. The diffusion coefficients of methane increased with increasing temperature, but decreased with the increase of density.
