The invention relates to a method of and a tank for utilizing a materialncomprising a porous material (14, 20, 27), a host compound, such as water, andnone or more lower hydrocarbons serving as gust compound wherein a novel andnbeneficial hydrate-like matter of the lower hydrocarbons are formed inside thenfine pores of the porous material (14, 20, 27). The invention is applicable to anmethod of supplying city gas, a method of controlling a feed of city gas, a city gasntank for supplying city gas or controlling a feed of city gas, a portable andnreplaceable fuel gas tank, a fuel gas tank for automobile, and the like by utilizingnthe formation action of the material containing the hydrate-like matter of lowernhydrocarbons inside the fine pores of the porous material (14, 20, 27) and thenseparation and release action of the lower hydrocarbons from the material. |
