A multi-mechanism coupled storage method for natural gas based on hydrate generation was explored to improve storage efficiency and reduce environmental impact.An experimental study on the effects of different temperature and pressure conditions and the use of different organic catalysts on hydrate formation and stability was carried out.Experimental results showed that the use of specific catalysts significantly improved the formation rate and stability of hydrates under low temperature(-5～15℃)and high pressure(3～12 MPa)conditions.Especially at-5℃and 12 MPa,when using the CAT-4502 catalyst,the amount of hydrate formation reached the maximum of 650 mL,and the stability score(decomposition time)was as high as 84 h.In addition,hydrate technology showed superiority in greenhouse gas emissions and energy consumption.Compared with traditional storage methods,it could reduce greenhouse gas emissions by approximately 40%and energy consumption by 38%.This study provides a new perspective on the efficient storage of natural gas and demonstrates the potential of hydrate technology in terms of environmental friendliness and economic feasibility.
