Description

吸附式天然氣儲存桶Adsorption natural gas storage tank

本創作是一種天然氣儲存桶，特別指一種儲存桶內置放有多孔吸附材料，能在低壓下高效率吸收天然氣的吸附式天然氣儲存桶。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.

隨著工商業的發達，石油的消耗量增長迅速，在大量開採、使用石油的情形下，其結果就是對地球造成空氣污染、溫室效應等環保衝擊。然而，幾次的能源危機，人們意識到石油是一種有限的資源，導致油價容易受供需影響而波動。上述環境保護與節省資源兩個課題逐漸受到重視，人們開始尋找影響環境較低的替代能源。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.

目前，天然氣被普遍視為最具有經濟價值的乾淨能源，因為比起石油和煤等其他化石燃料，天然氣燃燒後，在獲得相同熱量的情況下，產生的二氧化碳比燃燒石油要少30％，比煤要少45％，因此，天然氣已被世界各國廣泛應用於發電、化工原料、民用及商業燃氣、車用能源等領域。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.

有關天然氣的儲存技術，至少有壓縮天然氣(Compressed Natural Gas，CNG)、吸附儲存天然氣(Adsorbed Natural Gas，ANG)兩種類型。以壓縮天然氣(CNG)儲存天然氣所需的壓力高達約3600psi，相對的相關氣體儲存設備成本較高，且有安全性的疑慮。而吸附儲存天然氣(ANG)技術則是在一儲存桶中填入專用吸附劑，利用吸附劑豐富的微孔結構，能在較低壓力下，透過物理吸附作用來達到儲存天然氣的目的。There are at least two types of natural gas storage technologies: Compressed Natural Gas (CNG) and Adsorbed Natural Gas (ANG).
