Adsorbed natural gas
Adsorbed natural gas (ANG) is an emerging technology. As an economical and environmentally friendly gas storage method, its advantages are as follows: low gas storage pressure; The gas storage bottle is light in weight, has a wide range of choices for the shape of the gas storage bottle, and has high space utilization. As energy shortages and environmental pollution become increasingly serious, natural gas, as a clean and cheap energy, has become the preferred alternative fuel. Adsorbed natural gas is used as automobile fuel. Storage methods have attracted people's attention. This paper focused on the use of adsorbed natural gas as automobile fuel and studied adsorbents and adsorption processes. The life cycle method was used to compare two gas storage methods: compressed natural gas (CNG) and adsorbed natural gas (ANG). .By analyzing and comparing the impact of each data item on the storage unit volume of natural gas, a cost composition diagram was drawn, and the main economic factors restricting the development of ANG and CNG were obtained, which pointed out the direction of breakthroughs for future industrialization. The solid adsorption theory was discussed, combined with The Gibbs isotherm equation and the methane-specific state equation were used to derive a two-dimensional plane adsorption model. The Langmuir equation was used to calculate the adsorption characteristics and adsorption heat of the adsorbent. The micropore volume theory was used to calculate the characteristic curve, and the slit model was used to calculate the limit adsorption capacity. analyzed.
