Abstract:
A method for the adsorption separation of propylene and propyne, comprising selectively adsorbing propyne from a mixed gas of propylene and propyne using an anion-containing metal-organic framework material as an adsorbing agent so as to obtain a purified propylene gas. The anion-containing metal-organic framework material is used as an adsorbing agent in the method, and the adsorbing agent is a kind of highly ordered microporous organic-inorganic hybrid material, with the pore size thereof being adjustable within the range of 0.4-1.2 nm, and the pore volume thereof being adjustable within the range of 0.1-1.2 cm3/g. A large number of anionic active sites and a highly ordered spatial arrangement thereof allow the adsorbing agent to exhibit excellent propyne adsorption properties. Thus, the adsorbing agent has a very high propyne selectivity and adsorption volume.
