| titleOfInvention | A fullerene-modified MOFs membrane and its application in helium separation |
| abstract | The invention relates to the technical field of gas separation, in particular to a fullerene-modified MOFs membrane and its application in helium gas separation. In the present invention, fullerene molecules are introduced into the cavity of the MOFs film, so that part of the cavity space is filled, and the size of the cavity space is reduced, so as to solve the problem that the existing MOFs film due to the unstable window size of the helium gas and methane or nitrogen gas in the film. The problem of secondary mixing in the cavity can improve the overall sieving ability of the membrane; at the same time, the spherical structure of the fullerene molecule is used to change the transmission path of the gas molecules in the cavity of the membrane, and the curved transmission path is increased, so that the sieving path can be obtained. Extend, realize secondary screening, and further improve the screening capacity of the membrane. The membrane obtained by the invention has uniform thickness, good stability and excellent separation performance, and can be applied to the extraction of helium from natural gas. |
