摘要

PROBLEM TO BE SOLVED: To store a large quantity of city gas and supply it if necessary by arranging a city gas tank stored with city gas occluded by porous material under the coexistence of a compound to be a host, in a city gas manufacturing plant or a city gas supply base. SOLUTION: In a city gas tank for regulating the supply quantity of city gas, porous material 2 is stored in a tank container 1, and an in-out conduit 3 for city gas and a compound to be a host is provided with a switching valve 4. An opening, opened to the inside of the container 1, of the conduit pipe 3 is made to face the upper space 5 of the tank container 1. The city gas and the compound to be the host led in from the opening, opened to the inside of the container 1, of the conduit 3 are adsorbed and occluded by the porous material 2, and the occluded city gas is supplied to a city gas supply pipe from the conduit 3 at the time of being discharged by heating or the like. Such a city gas tank 24 is provided at a city gas manufacturing plant or a city gas supply base 21, and the city gas is supplied to various factories, facilities and each home via city gas supply main line piping 22 and branch lines 23.
