A load-leveling method through adsorption was presented to adjust the supply quantity according to the consumption rate of naturalgas with time. An experimental simulation set up was designed and used to test the load-leveling function for a real pipeline system. A storagetank filled with activated carbon together with a filter constitutes the major part of the load-leveling facility. Pressure and temperature of thesystem, as well as the reai gas output of the storage tank were recorded. It is proven that load-leveling by adsorption is technically feasible evenfor low pipeline pressure of natural gas supply system.
