Abstract
A method for storing natural gas by adsorption which comprises separating an available natural gas in an infrastructure side ( ) into a low carbon number component mainly containing methane and ethane and a high carbon number component mainly containing propane, butane and the like, and storing the low carbon number component by adsorption in a first adsorption tank ( ) and storing the high carbon number component by adsorption in a second adsorption tank ( ). The method can solve the problem that the high carbon number component condenses within a pore of an adsorbing agent and hence the adsorption of the carbon number component, the main component of natural gas, is inhibited, and thus improves the storage density. Accordingly, the method can be used for ensuring a high storage density also for an available natural gas. An adsorbing agent for use in the method is also disclosed.
