Abstract: ANG is a kind of new technology to adsorb natural gas. In charge and discharge process, it shows heat effects. The heat of adsorption is about 16 kJ/mol, and it influences adsorption capability about 20%. Based on the temperature field distribution of storage vessel and the comparison of structures with or without heat exchange, the heat effects of during absorption process was mainly discussed, the variation of temperature at different radial positions and influences of heat effects on temperature fields were analyzed, and experimental data were compared with. The results showed that using heat exchange structure had good effect to retard the heat effect of adsorption process.
