一维超微孔MOFs[M3(HCOO)6](M=Fe,Co,Ni)用于乙烯-丙烯混合物的分离
One dimensional ultramicropore MOFs [M3(HCOO)6] (M=Fe, Co,Ni) forethylene/propylene separation
摘要
Abstract
Olefins are important industrial chemicals,but the energy consumption in their production is very large.In this work,[M3(HCOO)6] (M=Fe,Co,Ni) were synthesized using solvothermal method and characterized by XRD,N2-sorption,SEM.We studied the pore structure effect on their ethylene and propylene adsorption properties.In a fixed-bed gas separation apparatus,ethylene/propylene separation abilities of [M3(HCOO)6] series were studied under dynamic conditions.The results showed that the pore sizes in MOFs can be rationally tuned through metal substitution.Larger pore sizes will lead to higher ethylene and propylene adsorption capacities,but lower propylene/ethylene adsorption selectivity and separation efficiency.Smaller pore sizes will increase the propylene adsorption,thus improve their propylene/ethylene adsorption selectivity and separation ability.In this work,we show that metal substitution on [M3(HCOO)6] series can effectively increase the propylene/ethylene separation ability,and this strategy provides an idea for efficient separation of light hydrocarbons.关键词
