Granular active carbon for natural-gas occlusion and process for producing the same

摘要

A granular active carbon for natural-gas occlusion is disclosed which can occlude natural gas at a relatively low pressure and has a high natural-gas occlusion capacity. The granular active carbon for natural-gas occlusion has first and second pores for the occlusion of constituent gas molecules of natural gas. The first pores each has a diameter d1, satisfying 2d<d1<=2.5d, while the second pores each has a diameter d2 satisfying 5d<d2<=6d, wherein d is the diameter of the constituent gas molecules.
