The creation is a natural gas storage tank, in particular, an adsorption type natural gas storage tank in which a storage tank is provided with a porous adsorbent material and can efficiently absorb natural gas at a low pressure.

With the development of industry and commerce, the consumption of petroleum has increased rapidly. In the case of large-scale exploitation and use of oil, the result is environmental impacts such as air pollution and greenhouse effect on the earth. However, several energy crises, people realized that oil is a limited resource, causing oil prices to be easily affected by supply and demand. The above two issues of environmental protection and resource conservation have gradually received attention, and people are beginning to look for alternative energy sources that affect the environment.

At present, natural gas is generally regarded as the most economically valuable clean energy, because compared with other fossil fuels such as oil and coal, natural gas produces 30% less carbon dioxide than burning oil when it gets the same heat. Coal is 45% less. Therefore, natural gas has been widely used in power generation, chemical raw materials, civil and commercial gas, and vehicle energy.

There are at least two types of natural gas storage technologies: Compressed Natural Gas (CNG) and Adsorbed Natural Gas (ANG). The pressure required to store natural gas in compressed natural gas (CNG) is as high as about 3,600 psi, and the relative associated gas storage equipment is costly and has safety concerns.
